Well I think I threw a bearing and looks like I'm gonna have to rebuild my 97 seems so soon only got 79k on it. Anyway, I know some about cars but engine rebuilding. Wouldn't mine doing it myself. I was wondering, should I just bore out the 350 or go for it and stroke it to a 383? If I'm gonna break her down, I figure i might as well get something out of it. I wanna end up with around 375 horses. I have a hell of a lot of questions either way so shoot guys.

Thanks a bunch. S.J.S.

97Z A4, K&N Cold Air, Flowmaster Cat-Backs, airfoil, MAF, March Pulleys, Eibach Pro Kit, TB Bypass and big as hell 315's on rear.

 

383

anyone ever see an LT4 383?

 

Either way you go, your going to have to bore it. With a high mileage engine, simply rebuilding the motor with stock displacement is essentially worthless, especially if u do plan to tear apart ur engine. If your not familiar with engines as u say, i would DEFINITELY not recommend that you rebuild it yourself. At least if it is done at a shop and they do something wrong, your covered. If u make the mistake while rebuilding, ur stuck. I know a fairly decent amount about rebuilding engines, and I just finished reading a 186 page book on rebuilding an LT1, and I don't even feel confident to build it myself.

If u wanna do a cheap rebuild, u can build a 355 motor just boreing the cylinder wall .030 over. As long as u inspect and have the machine shop clean up the rods and crank and replace the pistons, u basically have a new engine.

If u want to go a little higher quality with more power (but of course more $$$$) u can build a 383 motor. Granted it will be expernsive, but u will easily reach ur HSP goal and then some.
