Improving my 360 combo. Need advice/input

the PO knew he needed headers but got the wrong headers and had trouble spending $$$ on tti and did lots of bodywork to repair the fenderwell holes when he got the car. he just ran out of time/money to research and fix it right.

since the current cam is rated for higher RPM 3500-6500 the M1 will be god for top end. A mighty demon would have been a better choice with this radical solid cam. I think I can get it to work.

The Holley I have was originally tuned for my 410 hp 340 with the M1 intake. Im thinking I can just drop it in and go with it until I get some headers and go through the speed demon and get it cleaned up and tuned for a more radical cam.

I want this car to be more street but it will be setup like a strip/street if I use the what I have.

oh the dilemma

thanks OC
