hughes whiplash cam and other cam opinions

So you have an unknown compression 383 with 3.55 gears you intend to street drive a lot and you want a radical idle / lumpy camshaft.

While this may sound fun to you, my experience is that your fondness will dwindle quickly when you get this combo out on the actual road.

I would highly suggest having your pistons selected before proceeding any further.

Next in line is the potential mismatch carb and intake setup. If you are going to run a 4150 carb run a square bore intake to match it. I'd also steer you far away front a stock holley and vac secondaries.
