Recommendations for RAV Headers
 

So.......

1969 Firebird, full cage, STOCK front suspension, new RACK steering, FRONT Engine plate,
MID PLATE..

413 Cubic inch Original V block and heads.
Custom Cut Comp Cam... Duration @ .50" IN - 272 degrees , EX - 280 degrees
Lobe SEP = 109 degrees, GROSS LIFT- IN - .682 EXH - .667

QUESTIONS....

1) What size Primary Tubes / Collectors? (I May reuse these heads later on a larger CI engine later on).

2) Stepped Headers design???

3) FITMENT in the chassis with the front and mid-plate and rack???

4) More importantly... Who can I turn to for making them??

Can’t speak of the mid plate and front plate but mad dog made me a nice set for my 69 bird . Basically the same as a Doug’s header back on the day. There was an interference w the upper a arm but I sent him
Pictures and I think he’s probably made the needed changes for that now. I just had to dimple mine in that area . But you hav to jack the engine up considerably to get that header out that’s for sure.
I’d say it’s either that or custom on the car

Pretty sure Custom will be needed to be built on the car.The only sure way to have them fit.I think Maddog got rid of the jig for V headers.They used to make them for Nunzi.Tom

What do you guys think about tube and collector sizing?

Info for ya.

Ideally the tubes should step up in ID whenever there’s a bend of 45 degrees or more.

Just heard back from S & W and they don't do headers.

Anyone know in the Pennsylvania / NJ area that may be able build custom RAV headers if I trailered the car to them???

Seen a thread on another site looking for a header builder. They recommended Farks Supercars in Keyport NJ. Good luck.

I thought DCI was producing headers? http://www.dcimotorsports.com/produc...ir-five-parts/

Or maybe it was McCarty racing? I swear I remember seeing a big bin full of finished RAV headers somewhere online.

Not sure DCI of McCarty headers will fit a factory head?Tom

Pretty sure that was Don that had some made

Yep. That’s the picture I remember seeing

Those look to be stainless also, right?
