LS 3 crate motors..... Which one? Hey guys, I am in the market for a new GMPP crate engine. I have my eye on one of the LS3 crates. I like the EFI 525 but, I am a little worried about the street manners of the ASA cam with the 110 deg ls. I plan on installing the engine in a 67 nova with t56 trans. The car has power brks and AC as well as Heidts front and rear clips (9 inch rear with 4 link) What do you guys recommend? The 480.... 515......or the 525 hp?

I'd just get the basic one and with the money saved stab it with an LG cam with springs and pushrods and a tune, like a g5x3 or whatever their new one is. Those cams are making like 500 RWHP NOT flywheel. Guys are daily driving with those cams on vettes you my friend have a 67 Nova your a big boy so get the big boy stuff street manners will be fine stop worrying about it. You won't regret it sir
Personally...I'd find the least expensive way to get a longblock (like...maybe order a replacement engine for a Camaro rather than a GMPP crate engine)...or look for a 6.2 liter truck engine or something similar in a scrap yard...then go to Speartech or somewhere similar for a controller/harness combo...pick the cam you want, and have fun.
I'd search for the actual LS3 first rather than say an L99 (lower compression DOD engine). I think you'd be out the door for a lot less money if you go that route.
