From what I have heard, and what I plan to do next is porting out all intake componenets and make an afpr. Possibly a walbro fuel pump. Then, maybe just a little head work, cam and headers.


Then, I'm done. That's enough to put into this car. I have another that needs some love and attention.


Only problem is anytime that something breaks, I go ape shiit and want to replace everything with aftermarket goodies. My car has been leaking out the back out the intake for years now, but I can not justify ripping it apart w/o, again, going ape shiit.

I do not see a hi flow exhaust in your list. Maybe a nice dynomax flowmaster if you like their sound better. Plus a cheap hi-flow converter.

Before you get to torquey, tie up the frame before you start seeing cracks in your roof! ... if you have not already.

Later,
Mike

check out my mods.
on a 305 you DO NOT NEED bigger runners or intake. just port your plenum, no need for an afpr either.

All cars can benefit from an adjustable fuel pressure regulator. And a 305 will benfit from port-matching your intake manifold, runners, and plenum, too.

For the original poster, I'd add some SLP 1 5/8" headers.
