I am still torn on what to do with my headers. I have a set of ProParts and even test fit them with good results. But, I believe they are too small for my engine combo. I have heard they are a great street header, but for my combo which is race only, they may leave lots of HP on the table. This is a 496" low deck with SR heads ( I have some CNC325's to put on later) STR-15 with dual 800's with a Jerico in a 68 Cuda. I was hoping someone had run them or dynoed them against the pro-parts headers and could give me a comparison. The tube length on the ProParts are all over the place. Stahl doesn't give any info on tube length on their site. This is a link to the headers. http://www.stahlheaders.com/Frame%20New%20Drag.htm-Dave

why r u running 2 1/8 size? really no need to run that big (unless you're over 528" motor? i think you will lose bottem end torq & hp up top we have several cars running 9 with bigger motors and 2" headers i can see a step type header?? but unless you're prostock , some crazy, there is no need to be that big on headers i'm going to build a 500 an i very seriously considering 1"7/8 size header i think i can build more hp & torq over the 2" i have! i know of couple cars running deep into the 10s with 1"5/8 street headers!!

I was going with 2 1/8 because my engine is a clone of a friends. He picked up quite a bit switching from 2" to the 2 1/8". He is in an early B-Body in the 9.60's
I was more concerned about the tube length mismatch of my ProParts headers and was looking for an alternative. I figured while I was buying headers, that I should step up because of the difference it made on my friends engine.
Also because I will eventually upgrade my block and go bigger along with my 440-1 heads sitting in the closet hehehehe.

IMO, you are at the dividing line for 2" and 2-1/8". The average length of the ProParts is a little long for you, so if the 2-1/8 are closer to 32", I think that would be the ticket. Call Stahl and ask. Now if your combo is heavy (over 3400), small cam, low CR, etc. then the 2" might be just fine. Another gauge to help decide, if you are 3200 or less, and make enough steam to go low 9's and 7200+ rpm (finish line), the 2-1/8 should be the ticket. I love the 2-1/8 x 32" x 4" collector on my 511 CID. I ran the ProParts 2" back when I had the 470 CID. Looking at my sixty foot times I don't think the 2-1/8 are killing any torque! LOL 496 is just at the line depending on combo/application.

Jim,
I don't know the final weight yet, but it is a CM cage, and will have lexan, fiberglass fenders, hood, bumpers and deck lid. I am finishing the paint to put it back together. It is a new build so I have no idea what the final weight will be.
Going to have plenty of steam and should be somewhere in the low 9's.

i have been 8.30's at 162 wityh Pro Parts headers 3500lb car think they want to sponsor me?? Most people put too large of a header and never seem to pick up enough performance to justify the cost...You already have Proparts ?? then spend the $1000.00 or more on lightening the car or something else...but thats just my
....BAD A$$ STREET CAR.....
