the best part about the lm1 engine is the warranty. and as the speed bug hits(and it will) you could easily install vortec heads,performer rpm,nice comp xtreme cam and have a 350-400hp motor for only 1500 more. the 330 hp motor does have the vortecs and an intake and is an extremely great value for the dollar. it is hard to build one yourself for much less(with no warranty) good luck.

i would get some long tube headers and check out the jegs or summit 3 inch exhaust. it is not to loud in the car but sounds great wot

 

great choice! my firt car was (and still is) a 1978z28. i still have it!there one of my favorite years because they are the last cars to have the intermediate chassis before chevy went to the metric.that means the brakes are a inch bigger and suspension is beefier than the 79-81 style camaros.sounds like your on the right track with the drivetrain,your going to have a blast with this car!
