Breathing new life into the 318 in the Scamp!
Happy Birthday-make it a good one
I know this goes without saying, but if you're running true flat tops, even though those pistons will probably be in the hole about 0.040", and using stock size valves, you're running a .490" exhaust lift cam...please do clay up for P/V clearance and check retainer to guide clearance. I know it's not a big cam, but zero relief pistons don't make for very much wiggle room...especially on the exhaust side.
I'm pretty sure you commented on my cam selection thread earlier and I believe bomber even said anything north of .480" lift is getting close for requirement of guide work.
