spray
ok heres from a ultra conservative cant afford to break stuff street racer so take it for what its worth i used to run a 454 stock btm end with cast factory piston motor with 396 closed chamber heads on a 2stage 2cheaters plumbed into a 4spray bar plate id set the timing around 34 locked out and run it fat at roughly 7lbs of fuel pressure hit it with 125-175 on the hit and another 125-200 down track never had a problem nor broke a part in a 3800 lb car and ran consistant 680s in the 1/8th on small pills 125-125 n hit it harder on the street so fat and timing is the key so saving parts with your je pistons you should be fine start small work your way up as you are comfortable i used #51 autolites on spray and 52s off keep checkn the plugs if u burn electrodes start backin the timing out by 2deg increments till a good color is achieved and no plug damage youl be fine SPRAY IT MAN
