Just watched Nick on YT running the 520cube 71 GTX engine.

It has answered a lot of questions real quick for me!

Don't use a stock intake or stock exhausts lol... down

But the real question is?

How good or bad 'are' the Stealth heads... drinking

Can I 'out-port' them with iron???

We did buy a set back in 2005 and fitted them on a 543 engine with high compression.
It was pretty new stuff back then and I think it ran high tens in a street car (65 Coronet).

I would be happy with 11's with my homeported 902's and 511 cubes.
Start with an Edelbrock Torker and then hopefully an iron six-barrel... drive

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...
