the elk horns are the best flowing on the stock manifolds if your sanctioning body allows you to run them. I would def. run them if you can and not have issues getting them in there

I had trouble with ram horns hitting the cross member so I used a newer set of LT1s off of a caprice. 90 something model & they are awesome. You WILL have to use a mini starter or the flange on bottom will hit or mine hit the starter. I just use a header flange for the exhaust flange & it fit right up there & welded my bent pipes for exhaust.
I tried the ramhorns that turned back but the RH kept breaking & the LH always got in the way of something.. The ol log type ive seen some guys run them but you cant use solid mounts cause it always hit the motor mount. Some of the ol 305 manifolds that just dump in the back will fit but prolly dont flow well. But the LT1s work for me. They dump out the back but fit like a dream & they kinda go over the top instead of going down like most manifolds,I love mine, change plugs easy,,out of the way,,nice !

By the way, i run a factory stock type class & my motors in stock location, others may work better its just this was the easiest for my car with stock location. Dont have to cut or notch cross member or mess with the firewall, they bolted up easy,, good luck ,,I dont know how they flow or dyno I just know they work well for my car & its a metric..

The chassis dyno I use has compared lt1 which are supposed to be good... to plain old log manifolds and found zero hp difference. Maybe they needed more pipe or something, they both had just about 14-18"s of pipe on them.

Vortec truck/van manifolds from the late 90's they look very simular to the manifolds used on the 70's 350's.

Check ebay it might have a picture of them and you can decide IF you want to use them

They work great large opening and not choked down on the leftside ones, they are straight castings
