Nice Mopar Prochargerman!

We need more 71 Plymouths doing the 1320 lol... drive

Hopefully my 71 GTX will be back out after 20+ years doh...

I've been doing some small block porting too for my 64 truck.

But if I was gonna have a trick 71 it would be a 400 stroker methinks?

There is lots of info on heads and the all say ''don't go bigger than 90%' in the throat''... spank

But if you do the proper throat cut with a decent 'cutter' the the throat angle is already done for you...75 degrees or even 70 is OK!

The exhaust has a wonderful shape in the bowl area, so 'easy peasy'... beer

Carpe diem, quam minimum credula postero, thanx Horace!

There’s no point trying to fix stuff that ain’t broke,,, 'but if ain’t broke',,, you is not trying hard enough...
