Glenn, im goin right to a 4.56.. that little 3.750 stroke would be idling at the traps, with 4.10s...hehe THanks! I cant wait to get it running!

Brent,
There's a guy from Minnesota that ran/runs a Tempest in E or F /SA.... I spoke with him a few years back while I was working at the NHRA St. Louis Drags, he told me that he was running a 3.73 and it was the quickest the car had ever ran and MPH. They had started with 4.56, then 4.33, then 4.11 then 3.90 ...... a close friend of mine knows him well.
Food for thought! I'm rooting for ya!

He is running a 455, though... I have 4.10s in it now, with 455, and it runs 10.80s/122 at 5800 rpms... I will need 4.33 gears atleast...i have 4.33/4.56/4.88 for it.. 4.88s might be a little steep, for my needs, but, i have them, if i dont hit about 6500-6600 with the 4.56s. On the other hand, a friend of mine, with Buick 350 stocker, only running 4.33's i think...4.56s didnt pick it up, but that could have something to do with the intake manifold, on those engines...not as good as a factory Pontiac, In my opinion...I definitely wont rule out less gear, though...

I ran a L/SA Buick Skylark 350 back in the late '70's with a 4.10 gear.

[brent flynn]

I may be underestimating my engine, and have thought about trying the 4.10s before i change them to 4.56... I just dont think they will get the car 60fts quick enough... Guys in my class are goin 1.39-1.42, depending on weather... Of course, the engine has to make it to the 1000ft mark, before nosing over...hehe

A 4.10 is going to be pretty light for a 3500 pound car with a Dport 400. Maybe a 4.33 with a short radial might be ok. If you run your Bias tires start with the 56's.

[brent flynn]

Yeah, i pretty much gonna start with bias plys, so i figured the 56s would be the best way to go... Doubt that i will have radials in April... luckily i have ratios to choose from... i figure this engine will need to see around 6500 at traps, to get any kind of ET out of it...

Brent,

I have to agree with Todd , you don't want to leave anything on the table.
