I had to move one thing around on mine and build an air intake thats it. I used my existing downpipe that was 5". I have had fairly good luck with mine

 

jdgpuller its still a so vp and zzfab will build lines to fit as long as you would ship the manifold to them!!

 

sounds cool do you have any pics? I think I might do the same when I get some extra GREEN! I am wanting to build a complete engine with a p-pump, and use the one in there for a back-up.

I would love to see some pics of your whole truck, front axle and engine etc. if you don't mind?

 

its in the shop i should have it out to play when the white stuff is gone. i'll clean it for a good weekend and get "her" all perttied up and post some pictures. pm me your email and i'll look through and see if i have any from last fall and i'll send them.
