Here is my delema. I just found a near by source for bulk E85, not to mention here in Iowa we can usually find it somewhere close by at the pump. Do I build the motor for E85 or stick with pump gas? And when it comes to fuel delivery do I go the tried and true carberators or FI? If I go FI I've been told to look for something like the old 8 hole Crower for low rpm driveability. The motor I'm building is a Dodge 440 (going to become a 512), steal ported 84 cc heads, bottom end will be a 512 stroker kit my builder recomended with steal crank and forged pistons). CR is open to what ever I want it to be (thinking no more than 11.5:1 for pump gas). I have a Wieand TR for it and will be running a vertex mag. This motor will most likely go in my jet. Cam shaft hasn't been decided yet, but will probably trust the builder to recomend something as it's not my fortey. Any thoughts or suggestions?
