MoparMontana Posted May 25, 2021 Report Share Posted May 25, 2021 Now that COVID has ebbed and the new Bonneville lakester has completed it's new car shakedowns at El Mirage dry lake, it's time to dive into a few stagnant projects. First up is prototype #1 of my new "sleeper" head. This looks nothing like the end product, but is going on my '29 DeSoto roadster, Bonnie. I intentionally milled and polished it to inspect the quality of the casting, which I must say is simply outstanding. I then went a step further and gave it an old school hot rod prototype look. The real end product will look identical to a bone-stock 23" head, including provisions for the stock water neck, casting numbers, and provisions for the coil, linkages, and oil filter. Under the stock façade will be all of the benefits of my current EDGY aluminum heads - cast from pure ingot A-357 T6, and my Gen III "Bonneville proven" combustion chamber design. One exciting new feature is that the combustion chambers are going to be cast smaller than the current 74cc (about 9:1 CR), allowing for custom-order CNCed chambers of 8-10.2:1. They should be available in late-2021. Pricing will be about $1300. www.moparmontana.com 5 1 Quote Link to comment Share on other sites More sharing options...
MoparMontana Posted May 25, 2021 Author Report Share Posted May 25, 2021 (edited) Bonnie, a 1929 DeSoto Model K roadster, parking in '51 with a cracked block and a broken front left leaf spring, is now fitted with a '50 23", EDGY cam, Shanefelt intake, vintage Fentons, Holley 48s, and will be the the recipient of the prototype head. Tranny is a S10 T5 case with '91 Camaro gears. Axles and wheels are '31 DeSoto in order to get away from the '29s six lug wheels and split rims. Dash is '31 Chrysler. #BonnieDeSoto Edited May 26, 2021 by MoparMontana 6 Quote Link to comment Share on other sites More sharing options...

It's going to be a while yet. And since I won't be making any more EDGYs, the resale market should be strong for them if you decide to swap out for a new one. 1 Quote Link to comment Share on other sites More sharing options...
