15 degree intake

I am looking to put 15 degree heads on a 434 stroker motor. What intake manifolds will fit on the 15 degree heads (brodix). Also,will 18 degree intake manifold work and if so, what will I need to do for them to fit. Any help will be appreciated. please pm me any info.

Maybe new pistons. Does not Brodix make an intake manifold for the heads?

Visit the Brodix website, select which of their many 15° SBC heads you prefer and see their manifold recommendations. Any other manifolds are going to be problems.

Evidently you are looking for really big NA power, well north of 750 fwhp. You are looking at about $20/fwhp to get it right. Make sure your pockets are deep enough before you start emptying them.

Thanks for the help, but what other than brodix will work. I am estimating about 10k to build the motor.

Why don't you want to use a Brodix manifold? :confused:

I don't think $10K will get you a 750+ fwhp engine. If you aren't going 750 or more, why bother with the 15° heads and their large flow & high cost?

You could get a custom manifold from someone like Wilson, but it would be about 1/3 of your current budget.

What are your goals for this engine: power, torque, rev range, and vehicle application? You should really discuss this with your engine builder. If that's you, there some good folks who frequent this forum who will offer good advice.

GM has some intakes but if im not mistaken I think that Brodix made them for them.

OneFlyn95z28, How much was the sheetmetal intake without the cost of the nitrous set-up? And how long are the runners? Thanks, Rick.

Ellis, very nice setup! Did you have to send Hogans your heads for them to build you the intake?
