eBay LS Swap Headers - Test fit on a 67 Camaro

We have dynatechs on a 69 lowered 2" on Hotchkiss springs. Clearance work ok. I ran Hooker Supercomps on 2 cars and they tuck up nicely higher then the FBody oil pan.

Its still going to scrape, but at least it will be on a flat surfaces vs a vertical one.

Hey guys, just as a side-not to this thread, you only have to raise the tunnel on a 1st-gen LS/T56 swap to be able to achieve desirable U-joint working angles if you are using the stock frame stands and swap plates to mount the engine. The Hooker 1st gen LS engine mounting brackets and T56 crossmember mount the engine and transmission lower in the chassis than is possible using the frame stand/swap plate mounting method and requires no tunnel modifications to install either a 4th-gen F-body T56 or T56 Magnum transmission in the car while achieving optimized U-joint angles. The Hooker Blackheart 1st-gen headers are designed around this mounting geometry and provide tight tucked ground clearance.
