Anyone running these? 1 7/8" into 3" full headers, looks like no flange on collector (no big deal to add), look to be pretty equal length, and only $252.95 from Summit.
Need some headers for the '64 Savoy 440 project, and I'm thinking 1 3/4" primaries are too small; even though they're half this price, I'm thinking they'd be a big restriction. The other side of that is this thing needs torque to move, as it'll only have 3.91s, 3000RPM stall, 28" tire.
448", Stealths, will run 3" or 2.5" exhaust.
Whaddya think?

Bump for the "Dawn Patrol"

I think 1 3/4 would work fine but 1 7/8 would be a little better.

I had the Hedman 1-3/4 Elite headers on my old 440 and they worked good on that mild combo. You know it ran a best of 11.49. It was .030 over 440 with 906 heads and the MP .557 cam. I never tried a bigger tube but they seemed fine for that combo. Ron

The car will always run through mufflers: this is the drive-it-to-the-track-and-back car. I figure the 3" collector & exhaust should be OK, has an X-pipe & Dynomax bullets, will do turn-downs at rear axle initially.
The car certainly doesn't need to run 11s like Ron's - at least not unless I get greedy later! - but I want to make the best of what I have, given the relatively tall gear & low stall.
I would think someone's running the Patriot headers, with as many 440/B-body cars there are, but then again I didn't know they existed until yesterday, either. Curious also about fit vs. the cheaper Hedman and Summit 1 3/4".

What about plug tires on that passenger side. Looks a little intimidating. Plus you will have too put a late K and build a transmission mount in your car to use them.

Looks to me like 2,4, & 6 wires can run under, 8 over the valve cover.
Far as I know, the early B K-frame isn't an issue; seems nobody lists headers for the pre-'66 cars, but plenty of guys are running them. When I search Summit's site for '64 headers, the usual Hedmans, Doug's & Hookers are shown, even though most descriptions in print start with '66. The Patriots aren't shown for '64s, though.

Better look close, some will some will not. Hooker super comps for a 66 up will not fit a 62-65 car. The engine is further forward in the early car and steering box will interfere with number 1 tube. That is also the reason you cant just use any oil pan on a 62-65.
