3500 exhaust manifolds, mild ported

[ForcedFirebird]

It's possible, but Jason(Moonwell) was using flat gaskets, paper, copper, etc etc on his 3400 manifolds, and everything he did no matter what, they still blew out. I think he had to replace his steering rack twice b/c it kept melting the boot and @#$%ing stuff up. He went to the proper ring-seal a while before he got his headers.....

I didn't ues a gasket on my turbo downpipe and had no problems. Need to start with some 1/2" steel, and have it milled perfectly flat (after welding if warping occurs).

I sent a PM asking where to send him his money for these things but I haven't heard anything back in a few days. In case you missed the PM, PM me, I want em. Thanks.

I just replyed to your pm!

Would a cut to fit graphite gasket work? Like the material used on EGR gaskets?

[RedBird]

Yes, i had thought about that, but i was under the impression that the 3500 manifolds used the same style ring seal as 3400 manifolds, just with a smaller ring..... i wonder, can anyone get ahold of JUST the ring seals? if i can get two of those, i can have some flanges made cheap cheap

Haha. Gen III > Gen II for sure

[IsaacHayes]

hahaha. I said gen 2 is mpfi crap (stuff). Not gen2 is crap mpfi! If we want to put down something, lets say gen2 is crap! lol

[ForcedFirebird]

hey now. I've got a GenIII motor running on MPFI and it spanks most newer 3x00 equipped cars. MPFI FTW

FWIW, these are useless withough a flange. Which are a BITCH to find, you have to get to the cars at the J/Y before they pull the motor out, and that's hard to time just right. That's why i have a pair of the fronts sitting in my garage for the last 6 months

A flange is easy to make out of 3/8" or 1/2" steel if you have access to a mill (or would be pretty inexpensive at a machine shop). Then you could just weld them to pipe.

Gen3 = 3100/3400 (gen 2 is mpfi crap)

[El_Diablo]

yes, they will bolt up to your heads

[mcgavinz26]

Gen 3 being... mine is a year 2000. Is that me?

[El_Diablo]

they fit the gen 3 3x00's without a problem

[mcgavinz26]

I've heard these don't fit 3400 heads. True? False?

the front one sticks out 6 3/4" 's
and the rear one sticks out 6"
