Cam wise... it will still pick up about same no matter what the fuel, that's just a matter of ramp speed & some more duration. That's gonna help no matter what.
To be honest I think if you did injection with M5 on a 420 intake & lose 100 lbs you'll be where you need to be, without screwing with cam, so you could limit all your changes to external of motor. The added TQ the meth will put in will also really help cover up that glide lacking gear in the first 1/2 track.
Every dyno test I have ever done on Carbureted gas VS Carb meth, they always pick up 20-25 Ft lbs across board & usually about 20 HP. & I'm not using junk gas carbs to test against... it's just realistic gain to be expected if both carbs are good. I have not tested Gas VS injected methanol, (since it's a difficult thing to switch & test quickly) but everyone claims the TQ increase is even greater....
I might think about doing the cam as well since it is a fairly small cost and I will be into the engine anyway. Still giving some thought to sending the engine to you to put on the dyno for before/after pulls.
