wow that's a big cam! Not sure that will work with the EZ EFI, thy don't like to work well with very little vacuum.

Damn. I forgot about that and my math doesn’t account for that. I don’t know if one that does.

For S&G’s I ran your engine again but this time to 7k. This is what my math says.

And to get lobes like that somewhat reliable you’d need to be in the high .6xx to low .7xx lift range.

I agree it would piss off your EFI.
