I have a 68 Roadrunner. the largest TTI header is there 2'- 21/8 step header with 3.5" collector. is anyone using the Lomons header for a combination like this and maybe have some pics. I was told that a 2.25" tube and 4" collector would be about perfect for this engine but would need to go through the fender; at least two of the tubes anyway. what are you all using?

I think they were Indy header flanges, and just cut up some U bends, and made them. It's a nitrous motor, but just running all motor with 3.89 gears, tight convertor, and nitrous cam, it went 10.0's @ 136 on the first shake down runs of the year, at 7500 ft + DA, I think the tube size etc. is pretty close?

From what I have heard, being a size too small and having sharp bends right at the flange is a bad combo, worse than either by itself. If It were mine, I would go the extra mile and do it right the first time. I get away with 2 1/8 tubes, but I think the reason is they come straight off the heads and over the frame rail, so they have a ten inch plus straight shot out of the port before the first bend. I run a thirty inch long tube, four inch collector. 8.582, 160.18 mph best, 2905 lbs 549, indy 572-13, alky

Hi Tom Brian aka OldSchool has a custom set of big tube headers on his 580 motor that made 850+ hp.
