Ok, I am tired of trying to figure this engine out and the previous owner and the engine builder dont remember what what into it so I htink after the holidays I am goign to tear the top end off and see. What I know for sure: 1989 350 block bored 30over Trick Flow Twisted Wedge alum. heads milled .008"(supposedly) Scat 383 crank Manley 6" rods KB Hyperu pistons(will find out soon on what type ie dome, dish, flattop..) Comp Cam - unknown specs. Supposedly a carb'd cam, but is the largest cam that can be used with EFI(according to the builder) Compression - I think I remember the original ratio of 10.5:1 when it was first built and 11.5:1 after the resurfacing and new(thinner) gaskets. Rockers are stamped steel- unknown ratio What would you do with this combo? What cam would you use with a TBI? Looking for a cam with a good low end for towing but something with a decent mid and top end for the occasional races and truck pulls. Would like it to run on 94 so I am going to see about getting another set of thick copper head gaskets to bring the compression down. I am going to contact the builder again and see if he can either dig up records(if he keeps them) or see if he can remember.. Any suggestions? Thanks!
