I've been doing my homework a little now firestone and like the 325cc afr's.
My problem is that we've been in this engine deal for 3 years. We started with a 494 buick that the old builder assembled with the dots on the timing chain lined up like a chevy and if you know anything about buicks its about six teeth off. So total carnage when it fired busted valves, head, cylinderwall, bad deal, that was the first year, the second year a new builder and he clearenced everything to tight in the buick so 2 miles no bearings it was actually so tight it ripped one started apart on the first startup and the second on when the bearings failed and i tried to start it again on the side of the rode. that altogether was about 16000.00. Now were close to about 8500 on this chevy so were trying to pinch alittle. I sure do appreciate your help and advise. Its appreciated
