Interesting project,Dave. A good friend of mine
works in the Engine Shop at Mercruiser in Oklahoma,developing different engine
combos. A few months ago,he gave me a complete BBC tuned port injection system
for the engine I've been putting together for my El Camino. After owning a few
late model Corvettes with all their complexity,I'm not sure I really want to
deal with the hassle of converting my BBC to DFI. Yeah,I know the advantages of
fuel injection but the intake "honk" of a big Holley when the secondaries open
is sure hard to beat,too.
Maybe I'll pull the system out of the box this
Winter and see what I can come up with.

I didn't get any email from the list on Wednesday
April 28th. Is everyone just out cruising, enjoying the weather? I
drove my '70 to work for the first time this year, as it is almost 80 today in
Cleveland. woo-hoo!
Since it's been quiet, I'll post an update on my
latest project. I'm starting to gather parts for my EFI
conversion. I plan on converting my 406-powered '70 to EFI using the
MegaSquirt EFI controller and a TPI-based manifold. http://www.carcraft.com/techarticles/116_0403_mega/index2.html It's definately not an easy project. Just assembling the
MegaSquirt and pieceing together a harness will be challenging, let alone the
high-pressure fuel system and then tuning the thing. All of the software
is free, and the whole design (hardware & software) is open source, free
for anyone to modify to their liking. There's a real good mailing list
with lots of knowledgeable folks. I think I'm going to start with an 80s
TPI manifold setup, although I susspect it might be too restrictive for my
combo. I hope to score some of the intake hardware at the GM Carlisle
meet in June. I got a set of injectors from a '96-98 Mopar 5.9 for free
at work today. I'm not sure if they work or if they'll work on a TPI
manifold, but they were free.
I haven't seen any postings here, but
over on the MegaSquirt list, there's a lot of talk about the newer Wide-Band
oxygen sensors (WB02). Even for carb'ed cars (who put an O2 bung into
the exhaust), these WB02 sensors can show a real-time air-fuel ratio.
Unlike older O2 sensors (narrow-band), these wide-band unit are accurate when
you get away from stoich (14.7:1 Air-fuel ratio). I
imagine you could really cut down on tuning time with one of these, not to
mention increase the 'quality' of your tune.
