Wow!!!...13.8 to 11.1.......... best I could manage on my old stock 340 '71 Cuda + a .590 solid cam running a 250 shot cheater system with 110/110 jets was from 12.4 n/a to 11.01, again with a similar set up as before......pic was from 1987, I must've been doing something wrong, thats awesome!!, never seen anybody gain that much without using foggers.
