I may be screwing together a 470 wedge at 14.4-1 with iron heads. What fuel to use other than alcohol???Dave
That high of compression should be run on alcohol with iron heads IMO, but you already know that.
On gas I'd recommend a fuel like Sunoco Maximal It's like 114 or so octane. A step up from Sunoco Supreme which is 112 octane.

What's the stroker for Dave?
Greg; Kevin dropped of a 426 wedge for me to flog on. It started out as a 413 truck block that he bored to 426, it was in his son's RR drag car for a year and then was loaned out to a friend to finish the season with. It ran 12.80's in a 3800lb car. I dyno'd it with a 850 on it and it made around 380hp on my dyno. I pulled it down to see why it didn't make more power and found out even with the 11.5-1 max-wedge pistons in it, it was only 8.4-1. I just put a set of 452's on it yesterday that I'd milled .100+ to get 9.4-1 out of it. Also did some figuring and I think my 4.15 crank will fit which brings things up to 471 and 14.4-1, end up with .042 quench with a .070 head gasket. One of my typical junk off the garage floor builds. After I got off the computer I've got to go back out and finish bolting the 426 up to the dyno and make a few pulls. If everything works out I'm going to test a few different intake and carb combinations. Once I've finished those pulls I'll be pulling it down to mock up the 4.15 crank version to see if everything will fit. Ted; It seems I've been collecting concussions like some people collect speeding tickets. I hope this one is the last one.Dave

If it aint alcohol, consider running a water system. At 21 lbs of boost, my static CR is around 15:1. I run 110 Sonoco and a "Snow" water injection system.
