long story short Blown Alky BBC 20lbs 1471 Took motor to dyno ... 1600 hp My setup, 7720 and 7730, crank trigger and crab cap hvc2 coil. On the dyno we used a msd 8 or 10 box and a ss coil. After dyno removed intake to fix oil leak, put the motor in the boat, did not put a laptop on it yet. The motor fired up and was 10 degrees off (retarded) and no throttle response, but idled decent. Since it getting to be nuttier than squire shit and I am too. I got in the program and was trying to learn it, tried to move crank trigger pick up a hair to allow for 10 degree variance. now #1 cylinder only fires on say every forth rotation. I am running zoomies, I have timing light in one hand and other hand over #1 exhaust. When timing light flashed I feel the cylinder hit. On other compression strokes just hot air getting pushed out. #7 and a few cylinders on the other side are acting the same way. Called MSD, bought a new MSD crank trigger pick up (had a FIE on it on the dyno with different box). Tried ignition type on "network" and "6/7/promag" Tried changing crank signal. Tried firing sequence .. no change checked phasing, best I could with setback blower, even moved cap while running with no change. Ran extra grounds from battery to block, one head to another head, Just turned on data logger on the grid and cranked the motor over, it shows signal in and out consistently for the ignition. Testing the coil now. ( positive to negative posts .3ohms) why cant I get cylinders to fire!! (when they need too??) Trying to race Saturday for the first time this year. Please post or call or text 918-521-8421, if i dont answer I will call right back.
