I already have. I'm running a spread-square adaptor because of factory intake/holley setup. On top of that is a thick 1/4" gasket then a holley heat shield. I'm running a 3310 holley with 70 jets in primary. Timing is 18 initial, 36 mechanical @2000, and 50 total mechanical and vacuum. Runs great. Just a little aggravating with the heat. Figured if I could lower the coolant temp, it would help. I did notice Saturday it was building pressure in gas tank, because I could here the cap venting when I shut I off after a 35 mile drive home. It still has vapor line running to front but no charcoal canister, just a vented dust cap on end of line.
