Dyno Results - 355 - for my ole Stepside RC

What did the race gas do?

Race gas can give you some fudge room in milder applications to run a little more timing / make more power. Oxygenated fuels can be run a little richer and help a little, too.

On that setup, probably nothing. It's too mild to see any benefit from 105. Probably just what was in the tank at the dyno.

When cam manufacturers say that the cam is good to 1200-6000 RPM does it mean that the cam will idle at 1200? I know that's probably a dumb question.

is this supposed to be a street engine?

that's the powerband......idle should be just normal.

This is completely subjective. It's difficult to hammer down exactly what the powerband of an engine will be based solely on a set of cam specs. Many other factors play into this, such as transmission (and stall rating if applicable), gear ratio(s), tire size, vehicle weight, engine combination and compression ratio, etc.

Maybe as a general rule, in an otherwise stock engine/vehicle, it would get you close.

That was my point.

So if I did a cam swap to a .480 .488 from the stock 420 428 would I need a tuner?

Not a tuner, but a tune. Yes.

Thanks, sorry to the OP for the off topic,
