Cam suggestions

[Rich Fielding]

I am building a second motor and need advice on the best cams to fit.


12/1 compression 1425cc, GPZ head with 42mm/34mm valves running maybe 50-80hp of gas.


Currently using the 136/122 grind on my other engine should i use the same on the new one or go for a more agressive cam

Web cam makes a good cam 480 460 would be a good set up.

Web does make good and extremely durable camshafts.I would go .500 in/.500 exhaust with at least 275 degrees duration on the ex side.Set em 112/114 and watch the MPH climbup there on the bottle
