Welcome aboard thirdgen.org.

If you're willing to up your budget a tick, this is one bang-up deal http://www.sdparts.com/product/SD360...ripEngine.aspx . Mild enough for daily driver use, enough power to make you proud, already has some of the upgrades you're talking about (and needs others you're talking about).

If you really want to rebuild your engine, Speed Pro hypereutectic 12cc dish/relief pistons, rings to match, decent bearings, etc. Cam - the Comp XFI series is pretty popular (but higher lift than you're talking about), as long as your timing set is for factory roller type cam, you're good to go there ("lope at idle" and "TPI" should not be used in the same sentence). No need to get new lifters or pushrods (unless you know there is something wrong with your roller lifters). When you redo the heads have the top of the guides cut down for positive type stem seals, and have Manley valves & good springs put back in.

 

yea thought of doing that but really wanna keep the same engine in the car...I had a 87 iroc wit a 1999 vortec 350TPI engine that ran like a LS1. All I knew about the engine was that it had a cam, headers,chip,prom chip flowmaster...it was race ready but got cought up and had to sell it hope to get it back one day...just still wondering what I wanna do wit the engine in my 89 iroc..it only has 72670 miles not rolled over yet...
