Small block Holley Street Dominator manifold?

[694spdRT]

I have an older street dominator manifold off of a 360. Are they a good manifold like the big block version? In particular would it be an improvement on a warmed over 318 with a edelbrock performer on it now? It is for the Challenger and the plan is a 4spd OD with 3.55's.

Thanks

they are a decent intake , they do kill low end power as the small block seems to be more sensitive to the single plane intake in my experience  , my choice would be a LD 340  or better yet the LD 4B with 318 sized ports if you can find one

The low end loss of that manifold was what I wondered about. It was on a Lil' Red Express that was a real dog off the line even with 3.55's...we are putting a factory intake back on the truck and, hopefully, it will improve some.

It's probably a little too much intake for a 318. Usually a 4-hole spacer will help pick up the bottom end power and throttle response on mild combos.

Stick with a dual plane intake.

Or keep the manifold and change out the part that's underneath it.

I have a 440 or 360 Magnum(needs rebuild) that could go in but, then some other stuff has to be changed. The 318 is a fresh rebuild that came with the car and I was planning to use this as a summer daily driver. The 318 along with the 4 spd OD I am putting in would hopefully give decent mileage as I drive about 50 miles a day to work.
