1975 360 budget build

Define “A ton of money.”

A ‘75 has a problem with low compression and I suggest a head milling. And the below.
Edelbrock 1405, Air Gap intake, headers, hot ignition curve, Summit 6901 cam.
Your exhaust can be as easy as two mufflers at the end of two straight pipes ending at the axle. If you want a full to the bumper exhaust, Summit or Jegs has A body exhaust systems. With and without mufflers. I like there mufflers by the way. There designed to work with Hooker headers, but, in general, there the same as all the other one size fits all header. Add in a “H” pipe and your rockin dude.
