Re: 77 Cheyenne meets Ramjet 350 by N2TRUX
Ive been looking for an EFI engine to drop in my 86 GMC and this RAMJET 350 is looking better and better everyday. There is only one thing that has me on the edge. I was reading that this engine requires 92 Octane gas and with premium gas on the rise at $4.35/gallon I will have to pass this one up. Are you running 92 octane? Or is it possible to run it with 87 without upsetting the engine?
