I've got an old school mini-ram manifold (CC-fab, lol) and the welds connecting two of the runners to the flange cracked, so I had it re-welded and the flange decked. Year or two later, another runner cracked and the bottom of another one cracked. Had every runner re-welded again, and it's sitting at the machine shop now to get decked again to make sure it's flat.

My question is, should I cut some relief cuts into the flange? The flange is rusty and the runners look like all other weld-els, so I'm assuming the flange is mild and the runners stainless.

 

Sounds like it just wants to die. just let it die and rest peacefully.

 

Naaahhh... hotrex's soul must live on in infamy in the soul of this mani.

 

Lol, CC-fab been a while since I heard that name. Poor welding and fabrication will haunt it forever.

 

once the welds start cracking the manifold has cancer. you can't cure it, you can only send it into remission, but it will be back.

just put it out of it's misery

 

CC-fab for the win!!!

 

i once had a cc fab manifold. it had one runner noticeably longer than the others on an "equal length" design so it looked a bit retarded. thats why my friends called it the corky manifold, after the poor kid from that show life goes on. fucked up right.

fwiw i think those were all made with a harbor freight tig welder.

 

Honestly, everything on the manifold looks really good/legit except for the runner to head flange cracks popping up every once and a while. Machine shop called today to say it's nice and flat.

We'll see! Gonna say **** it all and let er' rip i guess, lol.

Anyone remember those good 'ole days of hotrex/devcon block filling/scamming/"where the hell is my manifold" threads? Ahhh... the good old days.

 

Full Race thinks it's a good idea. Hacksaw time?

 

I like the manifold cuts on the flange but if you cuts yours it will likely move quite a bit. Many finished manifolds are under some stress at the flange.

 

I still remember when josh had a "hot Rex" sohc piston/rod with a vafc lol
