Hey there, been a few years since I posted here. I know there is a few good engine builders that seem to always chime in so hopefully they still frequent this forum. Started building a new s10 project. So far i have a 350 1 piece block (that i got for free) another pall gave me a crank kit he had laying around. Also just scored a set of camel hump 194 heads for 150 bucks. The goal is to build something as cheap as possible to have fun with. Any how, question is. I found a set of dome pistons on eBay that i could probly get pretty cheap. There is a part number stamped in the top p5510 and underneath its stamped Manley. I called Manley and apparently they are to old to identify. So i was hoping some one could help with this dilemma. Thanks in advance
