I mainly posted this for Tony, I'd like to see what he's working with on his Scamp. From what i remember they were quite long. But that was what I saw when the car had -1 heads. It's difficult to get A SERIES of big tubes with good trajectory under the floor. Here's another pic I stored I think Al made for his B1 valiant.

We will likely be replacing these as well when engine gets freshenedand a number f changes made there too, but they fit very well. Carb on it was axed to. Also some more Valiant stuff all under chassis stuff as I had intended to reinstall the inner fenders but never did.Someone on here ended up with those tubes..Dont recall whom. All I have for stocktype stuff that did not get axed with photobucket. Unless you wanna see the ones on the Camaro "I am not ashamed to confess I am ignorant of what I do not know." "It's never wrong to do the right thing"

Thanks SPD Exhaust has nice cnc machined flanges. Stainless Headers in Minnesota makes nice water jet (or laser cut) flanges.

Yes, we’ve been using the ones you built for a lot of years. Can remove or install either side easily in a quick amount of time. No complaints here for sure.

Oh and i have some A body big block headers for sale in the race parts section When you throw in the durability part, I'm not sure if i was building my own I'd use M/S anymore, especially if you're spraying. Specifically for your application, the general pathway of "UP and OVER" then out the fender might be the best. You could error on the small side of pipemax if the lengths are shorter and the trajectory is nice. Thanks for all the additional pics that have been added! I have a decent inventory of bends yet but, apparently the materials cost has gone up a bunch. That may be your deciding factor. So, you're saying your old headers that served you well are for sale in the for sale section!?

I brought them to a very reputable engine shop for a dyno session and....they kind of told me [censored] are these ??? And they are not the correct size and length. To get what i really need, they are going to have to be fender exits. Short and BIGGER. Yea im a special case because im using a power adder and NA is of really no concern Last edited by n20mstr; 02/16/22 03:18 PM. ....BAD A$$ STREET CAR.....

Moving the master cyl might be in order and the smartest. Dartin's are on an RB with -1's so you can get a visual of what a gang of tubes may look like. The worst flowing will be #2 by far. Orient them firing into the collector in a circle too. Should be easier to fab putting the collector above the mid-level body line...

Yes master cyl is going inside with a wilwood reverse pedal assembly. Im really leaning towards front of the tire exit because i dont want to chop up the firewall....but who knows. Right now im stripping it all down to get the frame straight and get the inner fender wells out. ....BAD A$$ STREET CAR.....

If the results don't match the theory, change the theory.
