I have a performer intake laying around and a spread bore holley. Would take some figuring out on the throttle and kick down linkage. Future plans include an engine change thinking maybe 318 stroked to 390 but i do want mileage in the teens so nothing crazy. The way it is i don't think it will like pulling the boat and that's a big problem for me. Gotta kick it into 2nd for the hills as is with no trailer.
