I am working on putting an 81 Chevy 229 2brl into an 87 S-10 Blazer 2wd. This is my FIRST car project and I am running into dead ends. First about the engine....The 229 is bored .30 over, has a mild cam (not sure what size) compression is bumped up to 10-1, high rise Edelbrock manifold, and a custom built Holley 500 2 brl. to match the build specs of the engine. (Lucky me, at the time the engine was originally built by my father, my uncle was working as a head engineer for Holley Carb) On the back side of this monster is a 2 spd. auto. Powerglide tranny with a shift kit installed. This was a project my father started years ago and never finished. I am having 2 problems here. FIRST: I can't find exhaust manifolds to save my life that are in good shape. And SECOND: Can a distributer be used in this engine from the junk yard without doing harm to the performance of the engine?? I have a lot of money rapped up in this puppy and I cannot see spending $180 on a new dist. if one from the yard will do just fine.
