set up is a stock 68 ford 302 block 60 over 347 4 bolt main caps track ones solid roller 10.5.1 on pump gas 93 from any gas station. plug is showing no fuel and no timing mark . i have 65n 54f jet flowed @5.5 15 degrees total is where it likes it. should i add fuel psi and a degree of timing? i already removed timing and mph droped. also went the other way and it droped. i was going to go to a 82n 73 f @6 pounds and start @ 10 degrees timing what are your thoughts? and after i cut plugs i will post pix.
