Which style cast iron exhaust manifolds for a 60-66

[losthope]

Like the title say Im wondering what style cast iron exhaust manifolds work the best on a 66 c10 with a 350/th350 column auto?rear dump?, mid dump?clearence of mounts and starter?, Ive only have had trucks with headers and Id like to replace my long tube headers that hang below the frame with some cast iron exhaust manifolds that i can have the exhaust tucked up into the frame, im not a big fan of headers and i can pick up some exhaust manifolds cheap....Just need some guidance on which to use?

I always use the 2.5 inch Corvette cast iron manifolds from speedway. They are almost identical to the original manifolds used on our trucks but 2.5 inches rather than the 2.0 inch factory ones.

I also use their downpipe kit which fits awesome. My exhaust hangs no lower than the frame (using the Early Classic Enterprises crossmembers) and clears nicely around my auto trans, factory auto column and linkage.

Those look nice! I was planning on running 2" or even maybe even 1 1/2 like on my 50's car to give it that lowrider rappy sound and also just planned picking a set up from a buddy that has a few different styles ofexhaust manifolds from old projects....It just a stock crate motor nothing fancy just going to be cruising low and slow so not worried to much about air flow restriction factor for performance..

So ram horns x2 so far.... straight dump ram horns will work fine?...or would the ram horns that angle towards the back work also?

I’m also using ram horn manifolds, although my truck is a 1960. I’m using the angled back version on the driver side because it provides better clearance, although I’m pretty sure the straight design would also fit:

Thanks mark for the picture that helps to see it....After looking at that it looks like either style will work.
