Sounds like the HEI is the way to go! I have heard of problems with the drop in module before but I always though the whole unit would be different. Oh well the HEI is cheaper anyway. Thanks guys. BTW I am putting A/C on my truck and an alternater with a conversion to 12VDC, anything I should look for with the HEI? Its a 53 3100 with a 54 235 motor not a 57. Fat finger strikes again!! grin


I know the reality, don’t mess with my fantasy!
