Maybe @2Blue2 can merge your threads and keep everything together for you. :)


Now, to answer your question, just about any top end kit should get you there. A "cheap" example:


As for a cam, you could probably select a stock replacement for an earlier muscle car and be at the top end of what you're looking for going this route. This is actually the cam that I run in my car with 1.72 rockers and Trick Flow Twisted Wedge heads, and my combo produces 265 rwhp. I'd suspect you'd see something similar, albeit lower, with everything I've linked this far.


You'd probably want a carburetor in the 600-650 CFM range and you'll have to find a set of headers, but this stuff should meet or exceed what you're looking for.

Still dreaming of this...and a picture of your car...


Tell us what trans you got and post a pic of your car please.

I’m dreaming this

I think 9 to 1 pistons, 4v, and a small Comp cam (242) will make the 250 number with mostly stock heads.


Stock 77 engine was rated 134hp,
LILCBRA ’s engine is 265 rear wheel horse

This can be confusing and is not an apples to apples comparison
