Thanks!On my 65 Sport Fury 440, I have a set of them. It is tight with the 440, but easily doable. I ground the exhaust pipe flange on the passenger side for additional clearance. They would easily work on a 383-400 block, the 440 is just a little bit wider, which causes trouble on the Passenger side. Driver side fits like a glove.
With good motor mounts, you should be fine. I have heard that the 65-66 cars are the tightest fit, out of the C body line, when it comes to big blocks and headers.
Money talks..There you go..... I think it's time you threw in the towel. Whaddaya say?
Pm me ..... last I heard Eric wanted unreasonable money
