At 10.7, a Jones cam probably won't work; the Ica is likely to be too early, trapping too much pressure, and detonation is sure to occur. At 10.7, this engine will like a long slow lazy intake closing ramp.
Which, of course, will kill any chance at economy it might have had due to the hi compression ratio.
There is no better time than right now, to choose the right piston; it costs nothing to shop, and if the result of careful shopping yields 20 hp at peak, you know, in this case, that power-bulge extends all up and down the rpm range. And so, you can run a smaller cam to get the same absolute power, and simultaneously reap more torque at stall and less fuel-consumption at steady-state cruising. Since when did this become of no import to a streeter?
Shopping is free. A mistake in piston selection could be 20 years.
And tell me, who disdains 20hp at peak? That is pushing one cam size. that could easily be adjusted to 55/60 mph with gears, and make a tremendous difference in passing maneuvers.
A little time spent shopping, can mean decades of fuel savings.
Tight-Q is not all about absolute power. It's also about the fat low-rpm torque curve, the fuel-economy, the lightning throttle response, the reduction in stall and gears that can be employed, and about always having a lil extra torque for every occasion. It's more like adding 20 cubes by stroke,to your displacement.
