Getting Ready for the Magnum Swap. (help?)

No idea on the 1/4 but it's built to drive the hell out of and has freeway gears in it.
Estimates during the build were around 350hp with my small dual plane and 600 carb.

An Airgap and a 750 Holley is supposed to put it higher, but that's not what it was built to do.

It was built with fuel economy, reliability in mind as top needs.:D


This was last year before it went in the car, and the last pic out on Route 66 a couple hundred miles from here after the swap.

Sweet rodeo, with a semi tired 318 la ,the Flowmasters sounded NICE, whith the old school side exit exhaust .
How the new engine sounds ,with the side exit exhaust, intrigues me. My turbo muffler with turd downs shrieks worse ,than any horror movie .. You're thoughts?
