71-72 SBC Truck Exhaust Manifold Pics needed
 
All my trucks have BB's and am converting one to a small block for now.
What is the proper ex manifolds to use on these chassis's?
I need a few pics for lefts and rights along with their part numbers....
Thanx!

Driver's side?
So I am seeing that I may need the ones that kick back to the rear of the engine compartment based upon clearance issues???

2 wheel drive's are angled back like in the picture, 4wd are straight dumps. Both nicknamed rams horn manifolds. The straight dumps will work on the 2wd trucks. Just wouldn't be original.

*********************************************************
I have seen 2-1/2 center dump manifolds but was unsure if they would work on our chassis...
Has there ever been a 2-1/2 angle dump ram manifolds made?
If using the straight center drop manifolds, I suppose the exhaust tubing will have to be 45* bent to compensate for the difference???
What clearance problems exist on the driver's side for each manifold: center or angle ?

The 2-1/2" are corvette manifolds and straight dump only. They are 63-64? fuelie manifolds. I have a set of late 70's replacements from Chevrolet. Got them on eBay for $50 ea a few years ago. I will be using them on a 4x4.

I also used a set of straight dumps on a 72 c10. I don't remember there being any great problems. The drivers side was the only problem with a little squeeze needed on the pipe. It had a little contact issue with the shifter bracket. Each install would be slightly different.
