tire speed vs low gear ratio

(1/2) > >>

wideopen231:
Maybe my thinking is off base.After 7 months of job I am doing its highly possible.

 Wouldn't a higher(lower number) ratio give you more wheel speed at the hit?Provided you have enough power to get it rolling. Part of another thread and did not want to derail it. I had advice from a old guy in Kansas not to go 1.80 low but rather the 1.69 low because of shake. Hard to argue with those guys. LOL  So far only shake I have had was from stupid tune.which goes back to under powered thing.Always a probleM. NEED MORE POWER!!!!!!!

good question. bought an altered and we will run al least one v6 in it. the tires are 36x17-16. a lot of diameter for the v6. BUT, my tranny guy likes R&D and has built a t350 modified with a 700r4 first gear, but no changes for 2-3.  that first is 3.08. add a 4.56 and you get a wild granny gear. now the decision is what rear gear to use.
normal stuff is so boring......  ;D

THE FRENCHTOWN FLYER:
Let me respectfully suggest your tire us WAAAaaay too big for a V6. I switched from a 15 x 12 x 31.5 to a 15 x 10.5 x 28S last Sunday and ran my best 60' - 1.18 in years, down .13 sec from the previous 12 x 31.5s.

This is with a 305 ci inline six bracket engine (around 550 HP).

buickfed:
it had a bbc in it. that's the tire/rim combo that came with the car. if i went smaller it wouldn't look right. ;D

THE FRENCHTOWN FLYER:
My big tires looked baddass.
The littles looked goofy.
But it ran like JackTheBear with them on.
Now I realize how beautiful they look.
