 Clint,
 AGR steering boxes are rebuilt, while not bad, they are used boxes, hence
 the difference in price compared to Flaming River. I bought the steering
 column from Flaming River, so I sprung for the 12:1 from them. Another
$100,
 but it is new.

Re: [Chevelle-list] 3.73 or 4.56?

[tigergutt]

I'd go with the 3,73 unless you plan to only dragrace

 OK folks,

 I have the opportunity to use 3.73 or 4.56 gears in
 the 10-bolt posi I'm going to put in the '66.  The car
 has a 300+/-HP 327 and PG.  Anyone have any thoughts
 or previous experience with the 4.56 gears and the
 PG/small block setup?

 I drive the car to local shows, and want to be able to
 take it to Cecil on occasion.  A relative told me to
 do the 4.56s and nothing less, thus my indecision.

 Thanks,

 Jim

RE: [Chevelle-list] Exhaust System

[tigergutt]

Hi Larry,

On my chevelle with a SBC and headers I had the flowmaster setup, this due to a
suggestion I received on this list a while ago.
I was very happy with it but this time around I'll go with a 3stainless setup 
with
four borla mufflers due to my dream of allot of horsepower in my next engine.

I dont know about the size but I would spend the extra cash on stainless steel 
right
away
André

 Hi Larry,

 IMO, you should go with a 3 exhaust with an X crossover along with the
 mufflers of your choice.  I like Spin Tech, they're a bit loud at full song
 but have a unique sound that you won't hear as often as the bellybutton
 Flowmasters.  Dynomax Ultraflows are nice too if you want something a little
 more subtle (I used to have them on my Vette but wanted it louder for some
 reason).  I'm actually interested in hearing the new mufflers from
 Edelbrock.  The cutaway looks like a cross between Spin Tech and Flowmaster.

 Another place you might look is a company called Pypes,
 http://www.pypesexhaust.com/ they even have some sound clips online.

Thanks to everyone for your input. I spent a few 
hours going to all suggested websites, trying to learn what I can. Personal 
experience based input is very important to me.

It looks like we are pretty evenly split between 
2.5 and 3 inch exhaust systems. I've heard (and please correct me if I'm wrong) 
that having too much pipe could be detrimental to your torque numbers, because 
you need a certain amount of back pressure to scavenge (pull) the exhaust 
out...

I guess the real question then becomes does my 396 
with a Performer RPM Airgap intake and L78 heads redlining at 6500 - 6800 rpm 
move enough air to warrant 3 inch pipes. Is there a formula out there to figure 
that kind of thing out? Of course I'm willing to pay for the 3 inch 
systemif it sounds better and has no detrimental effect on my numbers 
grin I found Clint's comments interesting, using 2" head pipes and 
reducing down to 2.5" after the muffler...

Hi Jim: I've heard what everyone said  I agree with most. I've got a pretty healthy 327 in a 65 SSwith a M-20 4 speed, a 12 bolt  3.73 gears. I'm runningCoker 75 series redline tires about 28 inches high.It's great in town, the suburbs  back roads. On the highway at 60-65 I'm taching 3000-3200 rpms  people are blowing me off the road. I try to drive non-highway as much as possible. I also drag race it a few time a season. The future mayinclude a 5 or 6 speed. It's mainly a show car a cruiser. The max its been on the road is 100 miles one way. The Flowmasters are singing all the way!! It's noisy! 

If you plan little or no highway use  will be driving mostly in town  around, with an occasional trip to the drags, you could get away with the 4.56. If you plan to cruise  put it on the road stay away. Go with the 3.55-3.73. The 3.73 is about the mostversitile and that'sstretching it. Use the ratio that will best fit what your plans arefor the car. Be realistic. Witha 4.56 you may have to trailer to some events as necessary. I enjoy driving my car  am not interested in burning out my engine prematurely. Those 5 6 speeds with the .8  .6 gears are looking better every year!! Good luck with your decision  Happy Cruising!!!

Jim,I have a very healthy 350 cu.in over 400 hp in 
my 71 convt...had 3:21 stock gears...after the engine was done I wanted to drag 
it a few times a yr with my car club...so I went to 3:73...not a huge 
improvement in et but I like to drive the car and with the 3:73's the engine 
revs way to much at highway speeds and it is driving me crazy...I am repainting 
the car this winter and after the paint is done,I am either going back to the 
stock 3:21 or maybe 3:50.So I say if ya are wanting to drive the car any 
distance stich with the 3:73 or 3:50..if ya plan on doing a lot of racing then 
4:56 or 4:11

3.73 will be the better all around gear..especially if you ever hit 
the highway.  I've had 4.10's then 4.33's while primarily racing.  Now 
I have 3.73's and stuff the tallest MT DR I could find in there.  29+ 
tall to cut down the gear even more for highway speeds.  3.73's or 
3.55 might not produce the best possible track times but the 
driveability is worth the trade off.

Re: [Chevelle-list] Exhaust System

Hey Larry,
 Both 2.5 and 3 will get the job done.  I would look at quality, 
fit, and muffler sound that you like.  I ran 11's with a 2.5 exhaust 
and summit cheapy turbo mufflers and ran 10's with 4 flowmaster loud 
pipes!  The current Borla system fits in all the factory mounting 
locations and is made of SS.  I picked it up off the Summit clearance 
counter for under $300.  I like the flowmaster sound a little better 
than the borla but price, fit, and quality won out.  Here are a few

 exhaust systems. I've heard (and please correct me if I'm wrong) 
 that having too much pipe could be detrimental to your torque 
 numbers, because you need a certain amount of back pressure to 
 scavenge (pull) the exhaust out...
 
  I guess the real question then becomes does my 396 with a 
 Performer RPM Airgap intake and L78 heads redlining at 6500 - 6800 
 rpm move enough air to warrant 3 inch pipes. Is there a formula 
 out there to figure that kind of thing out? Of course I'm willing 
 to pay for the 3 inch system if it sounds better and has no 
 detrimental effect on my numbers grin I found Clint's comments 
 interesting, using 2 head pipes and reducing down to 2.5 after 
 the muffler...
 
  Thanks for putting up with my persistent stream of questions 
 here. As I dump all available dollars into this project while 
 dodging my wife's broom, I want to keep my future regrets to a 
 minimum.
  Thanks,

It's time to buy me an exhaust system. The system will go on a 
 fairly healthy normally aspirated 396 running L78 heads and 
 Sanderson intermediate headers with 1 7/8 primaries and 3 
 collectors. Those of you in the know, please help me decide 
 whether I should go with a 2.5 system or a 3 system. Also, brand 
 suggestions would be great.

I'll 
go with a 4,1 together with the 0,5 in my six speed, that makes 2,05 in sixt 
gear :o) that and enough power could make it go FAST

a five 
or six speed is the best of both worlds, acceleration and topspeed/low rpm 
cruising

  Hi Jim: I've heard what everyone said  I agree with 
  most. I've got a pretty healthy 327 in a 65 SSwith a M-20 4 speed, 
  a 12 bolt  3.73 gears. I'm runningCoker 75 series redline 
  tires about 28 inches high.It's great in town, the suburbs  
  back roads. On the highway at 60-65 I'm taching 3000-3200 rpms  
  people are blowing me off the road. I try to drive non-highway as much 
  as possible. I also drag race it a few time a season. The future 
  mayinclude a 5 or 6 speed. It's mainly a show car a 
  cruiser. The max its been on the road is 100 miles one way. The 
  Flowmasters are singing all the way!! It's noisy! 
  
  If you plan little or no highway use  will be driving mostly in town 
   around, with an occasional trip to the drags, you could get away with 
  the 4.56. If you plan to cruise  put it on the road stay 
  away. Go with the 3.55-3.73. The 3.73 is about the 
  mostversitile and that'sstretching it. Use the ratio that 
  will best fit what your plans arefor the car. Be realistic. 
  Witha 4.56 you may have to trailer to some events as necessary. I 
  enjoy driving my car  am not interested in burning out my engine 
  prematurely. Those 5 6 speeds with the .8  .6 gears are 
  looking better every year!! Good luck with your decision  Happy 
  Cruising!!!

RE: [Chevelle-list] Exhaust System

Title: Message



I know 
that a well built header will use the exhaust from one cylinder to scavenge the 
others, but I'm not sure about how the exhaust system itself can or will do 
that,
I 
thought that once past the collector it was only a matter of getting rid of the 
exhaust.
there 
was an article in a magazine about an instrument measurng exhaust backpressure 
and as I remember it it was all a matter the lowest pressure 
possible.

I dont 
think I'd use a step down in tube size, the entire system wont flow more than 
the smallest tube anyway. 
Maybe 
Clint tought of that because of the lower restriction restriction of the bigger 
muffler.

Have FunAndré

You guys have to remember that Larry's car isn't 
running a hyd lifter,oval port big block but a solid lifter,forged piston,four 
bolt main L78. Those things will easily rev to 7,000rpm and make their peak 
power well over 6,000rpm. It can handle a higher flow exhaust. I suggested 2.5" 
tailpipes because the exhaust velocity is reduced enough that the extra expense 
and more noise of 3" tailpipes isn't necessary on a BBC less than 427ci. The 
smaller tailpipes will help the low-end torque curve a noticeable amount and 
reduce the drone.
Very few streetable 400ci small blocks will have 
cylinder heads that can flow like L78 BBC's.

[Clint Hooper]

No way would I run 4.56 cogs with your engine/trans combo,Jim. It would be
overgeared a bunch. Even 3.73's are a marginal highway gear.
For a little more money,install a 200R4 or 700R4 with your present rear.
Best of both worlds.

Clint,

Everything you said about my engine is correct 
except I did go with hydraulic roller lifters and roller rockers. My motor man 
told me to set redline at 6800rpm.

I had my dyno run today, and you are right. It did 
make peak powerat 6000rpm.

442hp @ 6000rpm
467fp @ 4250rpm

Just a point of interest, airflow was 720.3 scfm @ 
6250rpm, which is as high as they went. What does the "s" in front of the cfm 
stand for?

That is so true Ron! When my motor man called and 
said "it's time", I drove to his shop like a madman! I walked in with a digital 
camera and video camera with a big smile on my face. I haven't built an engine 
since the mid 70's. Although I double-checked everything, there is always that 
little doubt until that engine fires up. Although I was hoping for a bit more 
power, I'm sure it will be plenty for my purpose... and I just love that
