what bbc headers are you using? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I purchased the performanceonline.com frame mounts for my '67 and was wondering what headers you guys were using for your big blocks? I also am curious as to runner size I beleive i'll be in the 540 flywheel hp range.

any big block guys out there?

I have Thorley Tri Y's but am concerned about clearance issues with a 2"/4" drop plus once I get the engine re-installed I don't want the headers/exhaust hanging below the frame. I am about to pull the trigger on Sanderson's Block-Huggers. BB4 I believe is the part number. Just am not sure if I will buy direct or through a Vendor.

Chevelle Hooker comps. I had to modify the trans xmember because the Chevelle headers sit up higher in the frame.

I also run Hooker Comps for trucks on my 67. Clearance is good, performance is good, sound is good, all is good except the gas milage.....
