headers for 396 nova

Ricky Clark · 05-30-2016, 05:46 PM

Can someone please tell me what the best size tubes would be for this combo. Looking to get some new ones would appreciate any advise.

Which combination? Makes a real difference between 350HP and 375HP.

The headers of choice would be Stahl, by ACP, talk to Greg at 717-232-2800.

Depending on the details that only your engine builder has, and the power you make, I'm going to say 1-7/8" to 2" step headers, around 34" long (17" long each step) and a 3.5" collector about 17" long. Again, that's an educated guess, it is probably a bit on the large and short side. But without knowing a lot more, it's hard to say. You could go with 1-3/4" to 1-7/8" and maybe longer, due to lower HP and RPM than the 375 combination.

Having had Hooker, Hedman, Lemons, and Stahl, I can tell you that Stahl is the only choice, nothing fits better, nothing works better, and you'll spend the difference in price making a lesser quality header work.

If it were a street car, or a bracket car, maybe you'd want to compromise. But not on a class car.

Larry, the number I posted gets you Greg, Jere's fabricator. He's building Stahl headers, ACP bought Jere's jigs, benders, and other equipment, and they hired Greg.

Over the years, with three race cars, the best headers I've had were always Stahl. I now have one of the last sets out their door before cutting back.
Quicker & faster than the two other sets I have, fit better, much better spark plug access, and don't bang the ground on hard landings. Can not think of one thing they don't do better than the other two sets.

I would go to them first next time.

Try a 1 7/8 primary tube with a merge collector. The collector should have a 2 3/4 minor diameter and a 3 inch major diameter. This if your convertor stalls to or shift point drops to 5000 rpm. Hope this helps.

Performance Welding would be my choice. Phone # is 530-367-4124
