I'm new to this board and am looking for some help. I'm finishing up a 347 for my 32 Ford street rod. It's going to be a driver not a trailer queen. 9.5 to 1 compression, Ford motorsports hyd. roller, Pro comp alum. heads, air gap intake, quick fuel 680 carb, HEI ign. I'm looking for a reommendation for spark plugs. Brand? Plug number? Gap?
