318 Poly talk

Happy Christmas to all in Moparland,

Are many folks working on their Poly engines anymore?
We have built a 402ci Poly with huge help from Gary Pavlovich.

Haven't got a decent intake as yet but have plans to modify a LSX one.
Basically a copy of the Hinkles 426ci 600hp Poly set-up.

They raised the ports by about 3/4 of an inch.
Ovalport design which is very W2 which is very trick stuff indeed.

There is also a SAM Poly in 2015 that made 600hp as well.
That was running a Hilborn injection, even more exotic...

The Chevrolet LSX is nearly right with spacer plates etc.

So is all this spacer machine work in house, or are you farming it out?

Alum poly intakes are unicorns nowadays. I'm also interested in a Ls intake set-up.

Good point there J_C_C_62.

I worked at a specialist V8 machine shop for many years.
Its 'go to' engine was the Rover V8 modelled on the Buick engine.

But they seemed to just stop being fashionable about 15 years ago.
So the shop work declined to a trickle and went under, so sad.

Now its hard to find a decent shop who wants to do V8 work now.
I do as much as I can with homework tooling and tricky stuff, farmed out.

The windjammer manifold was available for a while but has vanished from circulation it seems.
Folks snapped them up when they was affordable and won't sell them on it seems?

This was our best piece of machinery, you can do heads and block decks as well.
Also can be used like a milling machine to doe intake flanges as well.
