New 440 Build - Ignition Question

You "might" be acble to run pump fuel if you are careful with the timing curve. But it it were me and this awas a race vehicle, I'd run VP C-12 (110octane leaded) and tune for that. I had a similar combo with the MP .528 solid that went 114mph in my '70 Cuda on C-12. You will have less cylinder pressure so it might be ok. Mine would run on pump fuel, but it didnt run very well on it.
