Cam Choice

[dirtdevil]

UMP/Outlaw type modified on a 1/2 mile tacky track w/ American Racer KK704 tires. The motor is a 3.75 stroke, 6.125 rods with World Products heads that have been ported and have good springs, etc. I do not have any flow numbers.

A friend gave me this roller cam and card, it is an older Lunati. .430 lobe lift on both, 257 in and 265 ex @ 0.050. Will this work ?? My rockers are 1.6 intake and 1.5 exhaust.

What is the cylinder bore / size runner heads / the lobe center on the cam / methanol or gas ?

The bore is 4.155. The cam is 105*, the guy I got it from said he had it installed @ 102. Don't know on the heads, I think they are the 220's. They are ported to where some of the pushrods have sleeves into the the intake runners. Methanol.
