Need advise. This is the Cam Comp Cams recommended. As you know, you can call twice and get two different choices. Seems to be a lot of overlap in the duration. IS THIS CAM TO BIG?

Hey BigJim...
Comp Cams are very gd cams...i have run them for years in a # of different engs...usually they try to steer u rite on there recommendations...if u dont feel gd about there suggestions...try calling a few other cam manuf & see what they say before u make a decision...as far as ur mtr goes...everything sounds gd to me...i think u will find tho...that u will need a bigger carb...somewhere in the 850cfm to 900cfm range...u dont want to starve that mtr for gas!...also...maybe a little head work...match the ports (I&E) and clean up the pockets...otherwise...sounds great...just my .02 cents worth
