340-6pak Dyno Results

Yeah it has all those mods plus the heat crossover has been welded up [it was on a set of iron heads originally] pretty useless on Eddies though and it has also had a bit of a port job as far as I could get into the runners and opened up to match those big port Felpro gaskets 1213?? , the ones with the blue sealing strip around the port openings.
I run it with a 1/2" 4 hole insulator spacer not enough room to get any more under it, but it is enough to make a bit of a difference it seems to idle a little better and come off idle a little more cleanly. Prolly keeps the butterflies up out of the turbulence in the plennum a bit. I will get some cold air into it at some stage in the future as well. Every little bit helps!!!!
