Spare parts single 318 turbo build
Alright, measured up the cams I have. Right off the bat one of the cams only had about .25" lift on the lobe, so that's a stocker and it went into the round file. the second cam was .375 ish on the lobe so thats like .560 lift... yeah not happening. hah. The third was .295" on both lobes which is about .440" at the valves, the LSA is roughly 114 degrees. and the duration at .050 was close to 220/232 ish i tried to measure at .012" for advertised but it was not conclusive and i got frustrated. it was anywhere from 270-290 degrees. Maybe its an old 340 cam??? either way thats what im choosing to run.
I file fit the ring set i found, which has very tight gaps of .010 and .012. I like big gaps on turbo motors so i went with .028 on the top and .030 on the 2nd ring, mounted the pistons backwards to get a little more tdc dwell. Installed a no name brand of cam bearings. Threw the crank in, the pistons and rods, and cam. I recalculated the compression ratio with a couple of no-name gaskets i have on hand instead of spending 165 bucks on a pair of cometics and got 7.5:1. HAH. going to be a dog out of boost. Whatever. Cheap right?
