exhaust manifold

[chris989]

Hello Everyone,

Like a fool, i tossed my cracked manifold not thinking finding a new one would be difficult.

I have an 89v2500 5.7 burb. There is nothing at my local pic/pull. There are some online that look right but it always say not compatible with my truck.

My old one does not have the air port on #1 cylinder or the 02 bung behind #7.

I could use the 02 bung and block of the air port.

I call the 800 numbers and no one seem to know if the photo is correct or just a stock image. I missed Dorman again today, they are eastern time,

anywhoo,, if anyone can ID a correct part, or if someone has one,, I need a driver manifold so i can fire my new motor. I might switch to headers later but if i break in a motor uncapped my HOA will freak out.

all help is appreciated, I hope to post my new tbi build after i get it up and running.


Thanks,
Chris

forgot to say, I can not guarantee my manifold id original, it is just what came off the motor.

here is one from summit, It says it is for a van?

Here is a stock replacement from rock auto: They do have both sides.

Your not a fool, you just knew you'd upgrade to some shorty headers that match the oem y-pipe and bolt on

I say fire it uncapped, install the exhaust system when you can.
Tell the HOA people to just deal with it, or you will put up obnoxious xmas decorations and lights and leave them up for eight months.
The bolt pattern for the exhaust manifolds will be the same for all small blocks, the outlet angle does vary for a few models, just decide what you need or don't need to do the pollution control crap, and plug off un-needed holes accordingly.
