LS1 in a 72 Nova
S&P, BRP, ATS (and others) are some of the 1st web sites you shuold check to see what they have. As they have just about everything you need. S&P and BRP have project pages that show there kits being used.
Question you need to figure out what your plan is.. Front Accessories, Relocation mounts if not stock accessories, What A/C Compressor, if AC is going to be used. Also What trans are you planning on using? All of these question and more will come into play. So plan it all out before you get started.
Hooker now makes some 1st Gen F-Body Headers, S&P markes some also.
Good luck.
I used the carshop motor mount plates (knock-offs of the S&P ones?) along with the sbc short and wide motor mounts. These motor mounts allow the engine some front/back wiggle room (about 1/2in or so) and along with the plates, you can get the back of the motor to be right where it'd be for an sbc. Handy if you want to reuse your old tranny and dont want to modify the x-member (like me
).For headers I just reused some Hooker competition sbc headers, cut off flanges and re-welded tubes to ls1 flange. Their fit was bang-on with tube rearranging limited only to where they meet the exhaust flange, but this is pretty labour intensive so isnt for every one (but is so rewarding to see your work in the end!).
Like bczee said, if you have questions it's best to be more specific so we can give better advice!
