I'm not set on a single carb manifold, at all but, I've been steered to the ones I listed by several people. The other thing is, they don't make "modern" tunnel ram, for high flow heads, that I can find. My heads have 2.16 x 1.30 intake ports. The only tunnel rams that I know about for the 302's are the Holley Sniper and 300-275. the largest of those intake ports (300) are 2.00 x 1.19. Not to mention that used 302 tunnel rams, are getting like hen's teeth to find.Caprimaniac wrote: ↑Thu Jan 23, 2020 4:19 pm Sorry, cannot help you. But there’s something I miss in this inlet manifold thread. Why haven’t someone stepped up yet and shouted: Put on a tunnel ram and be done with it.
But you’re set on a low rise manifold, I guess.
This engine will run in the 78-80K range and those single carb manifolds will work in that range and have ports more closely matched to my heads.
