Thread: 496 Head/Cam Advice?

Tweet

howdy ,

I have built 496" motors for several projects ... they like the longer 6.385 rods , seems the rod ratio just flat works !
my daily driver is a 37 chevy pickup , tunnel rammed 496" I run flattop k.b.`s and factory 107 c.c. chamber large oval port heads w/ 2.19 x 1.88 stainless valves ..with the flattops there is well over .120 thousand`th clearance between the valves and pistons ,, run no less than .100 ,, just in case something happens to cause the motor to rev ... I never rev this past 6500 ,, I know it will go well past that w/ h beam rods ,,I don`t think any big motor needs more rev`s ...cam is a small roller , .671 lift x .295 dur. ......this combo pulls strong to 6500 r.p.m. ...... my race truck is an 85 S-10 ,, same combo , big brodix 320 heads and a .714 cam ....... I know you will enjoy the torque and power these motors produce ............ have fun , ratso
