Smile P-30 Headers

Does anyone have a good resource for purchasing hedders
for the P-30 chassis. I have a 79 24 ft and am in the process of purchasing a crate engine, 700R-4 transmission
and some new exhaust hedders.

Thanks for the help ya'll !

By a strange coincidence, someone just got a set, you could ask him the particulars in this thread:

of course high flow exhaust and better fresh air intake adds to the package too.

all of the true things that i am about to tell you are shameless lies. l.b.j.

I've installed headers in a 1981 Trans Am but I purchased them from just a auto shop many years ago. For future reference (I haven't purchased from them yet), I found a good internet source for headers at Welcome To Shop!.

I think a member on the site has a take off set for sale. You might want to post over there to see if they are still available.

There are also running threads on this topic on this site and here

Also, Jegs or Summit will have them new and they are specific for the P30 Motorhome Chassis

Any speed shop at all can install headers. i opted or coated hedmans. just picked up my '88 345 from Cw where they installed a gear vendor. the tech said it had a lot of scoot compared to normal. i'm happy with it. just make sure that whoever does it puts heat shields on the starter, plugs and oil filter.

BFRank, the high dollar solution is a Banks PowerPak.

HST, you can achieve nearly the same result with a good set of coated long tube headers, a true 2.5" dual exhaust system and a local fabricated cold air intake.

Most any local speed shop can help you out, as can many muffler shops. See also JEGS and Summit Racing on line catalogs.

Make sure that the headers you purchase have thick flanges -- the Banks are all stainless steel and have 1/2" flanges. They will not leak!

Frank, just replaced one side of my rigs headers after a failure.... likely due to a hanging exhaust putting too much stress on the headers. My choice has been Heddman due to the lifetime warranty.
This time I oppted for the 3/8 flange Elite model. Heat coated and $269ish from . Nice folks and two day ground out of Atlanta for me in SC.
Came with a broken box and no bolts so they shipped a new set right away. UPS picked up the open box a few days later.
Good luck with your project.

Doug Thorley ceramic coated headers from Summit Racing. These came with the smog nozzles on them to make them legal in California. They run into a set of dual Flowmaster 70's, vented out the left side in front of the rear axle.

Are you planning to put a 700R-4 in a motorhome?
They strong enough?

4L80-E maybe?

I agree, if you are putting headers on, make sure the rest of the package is up to snuff. Intake and exhaust can work wonders with new headers.

I've been doing some research over the past few years when I was considering headers for my car. The ceramic coated ones, or ones with a good coating can also help reduce heat, which from what I understand in the dog house of the mohos, can be warm already.

Every degree and CFM helps.

Computers manufactured by companies such as IBM, Compaq and millions of others are by far the most popular with about 70 million machines in use worldwide. Macintosh fans note that cockroaches are far more numerous than humans and that numbers alone do not denote a higher life form. -NY Times 11/91
