60ft, 330ft help

Like 4 weeks ago you couldn't get down the track and several posters tried their best to figure out your problem. Now your concerned over .020 in your 60' times? How about you make some laps and figure some of this stuff out yourself ?

Fair enough, sorry if i annoy you, yes we've had alot of issues with this car and i appreciate the help and listen to what you guys have to say i don't think i've ever been rude or unappreciative. also i enjoy talking about racing and seeing what people who've spent years getting the absolute most out of there combinations have to say, theirs a reason i come to this board to ask questions, its because i have tons of respect for stock and superstock racers, and admire what you guys do. i can lay off but i just like the advice and to keep sharing whats going on, this has been a big learning experience. and now that the cars coming around were still trying to find some et that should be in there and who better to ask. yeah i had already thought about gears, sue me i asked i question i had a inkling of an answer too, in order to stir some discussion and see if anybody had any other hints.

What low gear ratio is in the transmission?

[pfordamx]

its just the stock 2.45

I still think the converter is off.....or the engine tune somewhat. Even with lack of gear, the thing should sixty harder......at least .07. Converter is I'd bet 80-90% of the sixty. Gear is the rest. But if the timing/jetting isnt right, that could explain alot also.

What's the stroke on the engine?

[pfordamx]

engine stroke is 3.85

[Mike Rietow]

Torque converter like the other man said. I have a 23* sbc 3.875 stroke crank with a set of cylinder heads that flow 326 @0.700lift. 3250 pd car goes 1.27 60ft N/A with a 8.94 starting line ratio on a 28 x 10.5 bias M/T. Your starting line ratio is 10.05. if your'e optimum shift is at 7600rpm the observed stall should be around 6200 with a 3sp transmission, maybe a cats whisker more. I wouldnt change the gear without a converter adjustment. No way, it won't go down consistently.
