mill your heads
tune and possibly injectors
even with stock manifolds you're well past your HP goal, probably spending between $1000-$1500 total, and will have a more durable engine with better street manners than if you built that 283.
Yes its that freaken simple and cheap.
Ap72, I have exactly ZERO experience with anything LS. I have an '88 Monte Carlo 4.3L V6. The engine is shot, I've been planning on repowering it with either a Gen I or a Vortec style engine. How much harder would it be to repower with the LS style? Do the LS engines use the same bellhousing bolt pattern, and the same engine mounts? Flywheel bolt patterns? A 5.3, 6.0, or 6.2 from a pickup might be an "interesting" upgrade if it's not to radical of a project.
Also, what specs of cam regrind would you recommend? What's the cost and where can you get the regrind done? Anybody whom you would recommend?
