Not sure what else is out there now but when I put my 347 in my 66 in 03' the best thigh available was Hooker Super Comps 1 5/8" primary's and 3" collectors and they just barely fit with TCP solid motor mounts. I mean they almost touch both shock towers.....

i put the hooker comps in my coupe. having completed the shelby drop, i had to cut the excess off of the UCA bolts just to get them in. but they fit great.

Ill be putting the hooker super comps in my 65 w. a 331 the 2nd Fri/Sat/Sun of january. Ill throw an update up when I can.

I have FPA 1 5/8 x 1 3/4 step headers in mine. The fit is perfect even with cable clutch. No P/S bracket needed either.

I'm sure the fit is perfect with a 68 car w/ small block. He is talking 65-66 small block engine compartment.... night and day

Agreed about the engine bays. Apples to oranges, but these are 65 to 71 sbf headers. I can put 3 fingers between the headers and upper control arm bolt/stud on a 68. There wouldn't be any problem fitting them to a 65/6. Besides the quality I like the fact they don't hang lower than my frame rails. Downside is the price. Worth a looksee.

Whats a step header, and all I want to do is remove the blue, not buy new

 

[iskwezm]

so it looks like the average size is a 1 5/8???? i wonder if this is choking my 349???

S-CAR-GO ,, whats a step header, is this 2 or more size pipes , how much are they as I dont see prices

TomB, Prices are at the bottom of the page. Starting at $435 for nickel plating... Each set is made to order. Nothing off the shelf.

Look for the 65 to 73, Mustang/Cougar (new), 289,302,347 stroker w-standard head/Dart/Canfield/AFR. Step header. Click the link and theres a picture. The step starts as a 1 5/8 header and bumps to a 1 3/4 header after the 90* bend. This SUPOSSEDLY broadens the torque curve. I did have this exhaust on a stock 289 and the increase (SOTP) over stock exhaust manifolds was amazing. I didn't think it would make that big a difference.

Iskwezm, I think Accufab can build you some 1 3/4 headers. But I'd think you'd have more of a problem with traction than exhaust. LOL Wicked ride!
