you already bought it or you wanted to buy one ?

John at Waldrons going to make up a new right away, he did some research and the pipe he sent was for a 67 but when he looked up my manifold he said that it was for 68-69 so he will make a pipe for that manifold

do you have a part # for the 440 manifold, maybe they made it for that one, does anyone have one for sale or i will trade my b-body hp manifold

tti list it as a 383-400-440 they just have 2 different part numbers for the head pipe coming off the manifold. the log manifold i took off it waldrons fits this one.

the rusted one is a hp b-body manifold and the painted one is the c-body manifold #2863409. 67 and 68 383 and 440 are the same i thought and just the head pipe would be made different. it clears the steering fine

i have 440 hp manifolds on my 440 engine and told waldrons that when i ordered.

tried the pass side it fits my hp manifold and not the log manifold so perfect there. on drivers side i put the log manifold on and it fits that. and the log looks more like the b-body hp manifold might fit that. so waldron must have made it for the log or b-body hp. hope they don't give me a...

i have the c-body manifold it fits perfect but i think they made the pipe for a b-body manifold. one step up bigger cam then the hp 440 cam plus new comp springs

concern number 3 lol. the driver side is wrong. the flange touches on engine side no way on fender side, looks like it was made for b-body exhaust manifold. second from last photo is a b-body manifold looks like it was made for that one flange is pointed more down. last photo is the c-body one...

yes

mild rebuilt 440 with light weight pistons and thinner rings and one up from stock cam up and running in my 67 newport, was a 383-2 single 2" exhaust. just breaking in but has plenty of low and mid range power seems a little weak above 4800 rpms right now. will be interesting to see what the 2.5...

Waldrons exhaust 8-10 week waiting though.

thinking about using the HP manifolds on my newport, only reason is looking at the log vs HP is the HP have a wider opening where the exhaust pipe bolt to the manifold and being able to run a 2.5 pipe and not 2.25. any thoughts on that ?

he is dead wrong about headers, makes me wonder what else he is wrong about.

wonder why nick didn't go to 5800 rpms with the manifolds like he did with the headers.wonder if the power dropped why off after 5300rpms

sorry you took it the wrong way just trying to lighten it up a little.i was rough with some of my posts but was trying to get a discussion going so we all could learn something, and with other members posting there thoughts and facts.

if i had a choice on stock manifolds i would go with the 1963 300 J exhaust more down under than sticking up. like to see what they flow. is there any testing on those ?

you can see what they had to do with max headers to make them flow not even close looking to the HP manifold.

just kidding. no problem i will keep it. think it a c-body

let me dig it out and show a photo. i want a lot of money, there very rare and give a great horsepower increase over the log manifolds. lol
