Just installed a new Accel HEI in my 1970 454 with a new coil (2nd coil in less than 100 miles) and the car won't idle in gear, almost like it has no power, even wants to stall if I put the A/C on. 14 initial, 32 total all in by 3000. This problem has plagued me for some time. Also installed a new 750 Holley mech secondary.

Help!!! I want to drive this beast.

Need to be sure to have a good solid switched 12V to the BATT terminal of the HEI (Most pull it form the IGN terminal on the fuse box) and use a 12ga wire minimum. Don't use a ballast or resistor wiring for this.

are you absolutely SURE you timed it correctly?? you could have it off by a bit if you got the teeth wrong. and are you using a vac. advance?? if so what's it running with it plugged up and what with it hooked up at idle. sounds definately like a timing problem

Thanks for the input. How could I get the teeth wrong, the dist will only go in two ways, (180 degrees out). I had thought that it might be a few degrees off, because it wants 18-20 btc WITHOUT vac advance connected. Which seemed like a lot.

Why is this your second coil in less than 100 miles? As stated before, make sure you have 12v at the distributor as anything less might cause you to burn up your HEI coil. Let us know.
