HorsePower 360 build on Spike?
Those guys are idiots!
Nice to see they had to BEAT the cam into the block... NEVER a good thing. The cam bearings are too tight and the block likely needs to be honed on one or more cam bearing journals. It's crushing the bearing shell too much reducing clearance on the cam bearing. BTDT got the t shirt!
This is one of those thing where having a bore gauge comes in handy.
Then they put that POS carb on it. With a decent carb, 4150 750dp or 950hp, that engine puts out another 30HP is my guess.
