My previous run i ran a 12.2 at 114.
This is a T56 w/ 4.10's.
26x10.5x16 ET Streets

I never looked down at the RPM's but was well into 4th gear. I'll now be on a bigger cam w/ spray.

Will I need to get 28in tires to compensate? I'd rather get advice now, before i go out and bounce off the rev limiter

 

M6 with 4.10 gear if you want to shoot it 150 hp+ you'll want a 28" tire, yes.

you could maybe do 100 shot on teh 26" but you'll be crossing the traps at like 7K on spray, bad idea.

 

i plan to start off at 100shot, but will more the likely bump it up to 150. I think i'll shop around for some 28's to be safe.

 

Since adding the Vortech I have a hard time gettting traction with a 26" Hoosier which used to cut 1.45 60's with na. You`ll probably have traction issues also w/ 26" slicks, use the 28" for better traction + gearing.
