Nothing wrong with Poly questions.

Semi-hemi engines don’t squench like wedgie engines.
Stroking is the easiest way to ‘up Poly compression’ methinks!

Folks have been spoilt with LA engines for over 50 years!

But the lowly 318 Poly can be made to work...

The old trick was to overbore to 4 inch and turn down a 360 crank.

But now we have high compression 402 kits for the serious Poly Folks.

400 horses not beyond a stout Poly build.

We are moving on to a 500 horse Poly build now, with a blower...

Dare I say it?

Chevrolet intakes and headers from the LS range... whistling

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...
