recently gained access to a small cnc machine I'm machining a head but I don't know if the crank will like 11 to 1 compression if not 12.0.1 espcially with a heavy cam. anyone have some experience with this?.

recently ported the intakes and the exhaust im wondering how to get rid of the ridges in the exhaust im thinking of welding somehow like brazing or a low heat weld .one will it work and two will it hold, three whats risk of damaging weakening  the block?

the wrist pin I have is for a model 252707 its from a .030 kit im using the previous piston with a new set of rings .the problem is when installing the pin it seems a little too snug in the piston and the connecting rod moves but it takes a tiny bit of effort . ive built a few chevy 350's and one or two pontiac 400's but this seems a little out of place. 

any races in RI CT area?

finally built the motor she's all prepared for her first run. I just have no clue of how to break it in?!? any tips george,don ,rooster would be greatly appreciated. I have royal purple break in fluid an several quarts of straight 40 racing oil.

I picked up this motor awahil ago it runs great thinking of building it. I'm wondering if I can put the oil pump and system on it.and changing the carb.is it worth the build?

im building a 12hp briggs stock prepared for vo tech any pionters would be really heplful. im thinking of putting a 18hp carb on it flywheel key valve springs and retainers, ported the intake a little and an e3 spark plug
