The Stovebolt Site Forums The Shop Area The HiPo Shop Selection Exhaust Manifolds for a 350

I own a 1950 1/2 ton Chevy PU. I have welded an aftermarker V8 crossmember on which to mount my engine. I carefully positioned the combined transmission and block to ensure proper placement. My next big decision is finding exhaust manifold that will fit properly.

Has anyone done this? What manifolds did you use?

After selecting and mounting a manifold I will take the truck into a muffler shop to have them custom build my exhaust system. Any suggestions?

I have heard some guys say that they used "Ram's Horn" manifolds; they dump straight down in the middle of the block. The problem is the clearance with the steering box (unless you relocate it to outside the frame).
Log manifolds might work, especially if you could use 2 passenger side manifolds and have one dump towards the front, so you could "cross over" to the othe side where there is more clearance.
You might also consider offsetting your engine 1-1/2" towards the passenger side. Then the Ram's Horn manifolds (or headers, if you so desire) will clear.
I don't know if Sanderson cast iron block hugger headers will clear; maybe someone else will chime in on this.
Also, Headers By Ed . They have been around for a while and they sell "make-it-yourself" sets............

There's an old article floating around on the internet called "V-8 Juice For Your Stovebolt." It was written by Pat Ganahl back in the seventies, provided some good tidbits about the basic V-8 swap without all the excess geegaws. I believe you might find a link in chevytrucks.org in the tech section. long story short, he recommended a 307 c.i. exhaust manifold (still had to move steering box out). My own personal experience with a V-8 Vega (first car) would be to try the 305 c.i. manifolds, switch 'em side-for-side on the engine, dump the exhaust pipes down at the front. This should give you all the clearance you'll need. Hope this helps.

I've been using an exhaust manifold off a 1968 Chevelle. The ports on it are under the spark plugs so that makes changing them easier because you can see them and also makes for easier wire routing. The exhaust has a bend inward toward the motor right about where the stock steering box is located" so that free's up some room. The part # is GM 336710 LH

My stock 67 RS Camaro also has this type of exhaust manifold.
