Granted, I AM a gasoline engine kinda guy, if I HAD Too and had the means too, you really think I'd be putting a Diesel in my current '67 if something happen to the 383? HELL NO!
Granted if I got a CAT at a price that I couldn't refuse I'd think about it, BUT IF I had the $$$$$$ and the 383 went, and needed to be replaced.............
426 Wedge or HEMI all the way, a legend engine be taking that saddle...... Probably if I were too, a 528 HEMI, with it looking like a 426 Hemi 2x4 inline intake, and Aluminum "MOPAR HEMI" black valve covers with fins.......
NOW I KNOW, and you should too.............................that I'm dreamin'!!!!!!
