I've built 2 383s.. 9.8:1, stock heads and vavle gear, one dual plane one single, both with 750 3310 Holleys. I used the XE268 in them. Thye idle at 700rpm, pull from idle to 6K, and have no issues. I dont think any MP cam is the way to go for this one. Get something design in this millenium and that is made without the usual production issues. If you do run an MP, then make sure they degree it because it's going to be off.

Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
