stock 5.2 magnum power

Might be an issue with a TQ. An adapter would be needed unless it is a M1 single being used. Not a great idea IMO to use that intake at this stage.
IMO a simple 650 AVS styled Edelbrock or a 600/650 Holley VS.

A small cam would be a great way to improve power. Under [email protected] would be good. You'll retain good mileage.

Good points, Rob. the 204/208 Magnum smog legal grind, would rock here. I would give Oregon Cams,a call here. 1110 Hughes springs & retainers to match, please.
