Stockvs Ram horn manifolds

[longbeach]

Hi, I have an 86 K20 350 V8. The headers that came with it are rusting out. Would like to go back with cast iron manifolds either stock or maybe rams horn. Does anyone have any experience with the rams horn ones. Clearance issues. Straight down exit or rear facing? Thanks

The rear shooting should fit all squares, can't say with a manual. But it shouldn't contact the z-bar itself.

The straight downs should fit 4wd, may have some motor mount clearance issues, but should work. I don't think they will work for 2wd, I don't know though.

Was about to swap to the straight downs on the burb, then put the rear shooters on another truck.

Straight downs are 2.5 inch. Rear shooters are 2 inch.

I really really like my exhaust note. It's very low and unique.

The performance Rams horns won't work on a square,if that's why you were going to rams horns. The ones you want for performance are 2.5 diameter and shoot straight down. The angled Rams horns are 2 inch.

ram horn way better the regular manifolds but if you get regular manifolds get the hooker ones they also make rams horns and get the bigest out let diameter

^^^^ 2.5” are the only ones worth while

The only reason for the common belief that ram horns are better is due to the 2.5” ones pictured above from a H.O. 327 Corvette. The vast majority of ram horns out there are no better than any other manifold.
