Pump gas compression again

I think you’ll be fine with that much cam with proper tuning. Careful with the AV/Gas, it’s got some stuff in it that helps it burn at high altitude that’s pretty aggressive on rubber line and parts. Even the low lead has eight times the lead of regular leaded race gas. Its more of an octane booster, about two gallons to five of premium pump gas. With the timing optimized for full power, it’s probably still going to have an octane requirement of around 95 or better when it come up on the cam at full throttle.. It’s usually more expensive than AV/Gas, but 50/50 race gas to pump gas will get it by during the all out runs without as much potential for making lead deposits/fouling. What kind of ignition are you using? Running a dashboard retard dial isn’t mandatory in this case, but is a nice convenience to have in case you get a load of bad gas.
