Running a 306 with 4.10 gear. Currently running 27x10 ET Streets. But thats what came on the car. I will probably move to 26x10 while still NA on the motor. Will probably move back to 27" or possibly a 28" tire once I start to spray it.

MPH is 109 - 110,.. even though my 1/4 mi ET's are still 13.09's. Aiming for low 12's high 11 et's NA. Once I get that dialed in,.. will be spraying for some 10 sec et's.

Cleveland motors make pretty good torque compared to windsor motors. They breath a whole lot better also. Bigger headers and longer gears then you would with a windsor motor. Think of the Cleveland as a small big block.
