Ok I’m starting to put together my game plan for the engine build for my 72 Duster. I have built 383’s and 440’s in the past and like them both. I’m leaning towards building a 383 and wanted to hear from you guys on what kind of ET’s you have been able to achieve with a similar combo.
The car has been stripped of all interior. Has fiberglass hood, fender's and deck lid. The hood and deck lid hinges and springs have been removed. Still has all the factory glass. Stock front suspension. Has super stock springs 8 3/4 with 4.56 gears and spool. Has 13.5 x 28 slicks. The guy told me it was a 10:50 car with a mild 440.
So far for the engine I have a set of stage VI heads. The heads are as cast but I plan on polishing the ports. One reason I’m leaning towards the 383 is I think the heads will flow enough for the 383 but might be a restriction on a 440. I have an idea of the engine I want to build but I would like to hear what kind of times you guys have been able to get with a 383 in a similar car and what was your engine specs.
Thanks
