Ported GT350 manifold

[Chad1986]

Just curious has anyone tried a ported GT350 manifold? Wondering if it would have better power than a ported 18? or about the same.

Stock for stock, they make similar power but the GT350 mani will carry the power longer, which is better. Porting will improve upon that. But dollar for dollar, the 18 wins.

GT350 mani will carry the power longer,

**If you have non OE cams. There have been several dyno tests that show negligible/within run-to-run variation difference above 7000 rpm between the 18 and GT350 manifolds on stock GT cams. Below that, the 18 is stronger, so it's a pretty easy choice. With cams that are optimized for higher rpm, the GT350 and CJ manifolds will shine.

Depends whos tuning it!

Ohh and what fuel.

So I did fall down the rabbit hole yesterday and bought a set of stage 3 cams and long tubes from beefcake. Sounds like a ported 350 or cj is in my near future. With those do you think 47lb injectors will be enough to run e85 on that setup?

yes

stage3 NA cams CJ and E85 should be good for about 500whp. ~

HMMM wonder if NA 10's are going to be possible
