With a 3.73 cog,I would definitely go with either a .64 or .68 Fifth gear ratio
over an .82. How tall are your rear tires? Both Herb and Michael are running
tall diameter rear rubber which has to be factored in.
I'm running a D&D Viper T56 with 4.11 rear cogs and my 335/35/17's are only 26"
tall. In Sixth gear,I'm seeing 2,000 rpm at 70mph.

Good afternoon Chevelle List: I am planning to have a Tremec 5 Speed
installed in my car this spring. I am requesting any & all thoughts & advice,
even if it's just thinking out loud. This is an expensive item and a one shot
deal for me so if there is any info or experiences out there I should know
about, please don't be shy!
Aside from normal installation situations, one item that has been brought to
my attention is that there have been problems & difficulty in power shifting at
high rpms from 2nd to 3rd. The car is a fair weather weekend driver only, an
occassional, OK, more than occassional few gears on the street, with a trip to
the drags once or twice a summer. My reflexes aren't what they were 40 years
ago & I don't do power shifting anymore anyway. The next item is whether to go
with the .64 or .82 5th gear. Would I be giving up all top end punch with the
.64 for the sake of really low highway rpms or would the .82 put me whare I
want to be & still give it some power if needed. I've done the math on the web
calculators but it appears to be a judgement call. 1st gear will be 2.87 and
the rear will be a Moser posi 3.73. The car is a 65 SS with a .40 over 327,
