SP2P 2bbl worth the effort?

FWIW, I didn’t mention that my Magnum was also under the states thumb of the upgrading to Ca. emissions. I had to have a working egr valve, vapor canister hooked up, catalytic converter or as in my case, 2 of them. I got them from Summit and they were a high flow design. It did pass emissions tests.

The otherwise stock ‘79 - 360 did keep up with stock mustands of the day.
