Been awhile since I've been on here, been a tough few years, but I just traded my 90 Ford F150 with a 300 for a 37 Dodge PU that has had an amateur restoration with a '55 Plymouth 230. The plans right now are to order the Fenton repop exhaust headers from Langdons along with the T5 transmission adaptor. I have the choice of several intakes and the eventual plan is to pull a trailer to swap meets. How much should I mill the head to use todays gas?
