1970 351c 4v Headers

Make your Cougar run faster, handle better, and jump higher... okay maybe not jump higher. If you feel the need for speed, this is the place.

Looking to put some headers on my cougar and was wondering if anyone could point me in the direction of a good set of long tube headers.

I used Doug's for the transplanted 351C in my 1969. They cleared the steering box but required some Zbar mods and some clearance of the bell housing. They angle down a bit too much at the collector too. I'm not real impressed overall.

Try FPA headers www.fordpowertrain.com, spendy but very high quality headers. Stay away from hookers the exhaust port mismatch is terrible.

I remember an article written back in the day that dyno'd a 351C once with stock exhaust manifolds then again with headers. The difference in preformance was minimal. The people that did the test were really impressed by how well the stock manifolds flowed.

I can corroborate the observation Tomcat cites. My 351C M-Code dipped into the 13s (barely) using the cast iron stock manifolds. However, if you have the money to burn in the budget, call the FPA guys on the phone and grill them on whether their header require a bracket to lower the power steering cylinder and its ram. That was always the dumbest feature of longtubes on Ford intermediates - and still IS, for all the national brands. Maybe FPA figured out a solution.

R.B. on FPAs you still need the drop bracket.

I run the Hooker Ceramic Coated Comp's for 2V heads and have been into the high 12's with Isabel at over 4K lbs.

P.S. Buy the bulletproof drop bracket from WCCC. Spendy but no chance of ripping the nutserts out of the frame rail.
