I would hope I could run a 4V of some kind. I have 3 or 4 good 600 Hollys also a 500 Holly Ecomoziser that I have used on a number of 283/327/350 V things that has worked out real good. Do you have a web page on the rear sump oil pan yet?? Will the 4200 mate up to the older th350/th400/200r4/700r4 transmission.I guess the starter would be another issue also.. I know all this has been hashed over on thas board but, I just didn't pay attention at the time..!! Jerry
