We currently have a Cole Flatty with a 522'' blown injected gas deal. It runs on 118 octane and you're either idling or full throttle. I assume the poor mid-range drive ability is because of the barrel valve. Well now we are looking at a 19'6'' Hallett v-drive with four seats and we would like to put some version of our motor in it.
The current motor has a bowtie block with a chevy crank and aluminum rods. We also have a brand new 540 with a dart block, scat crank, scat rods and JE pistons. Both motors have large solid roller cams. We have a set of dart aluminum heads, and a set of brodix aluminum heads, and I think we would use which ever head would yield the lowest static compression. We have roller rockers with a stud girdle or jessel shaft mount rockers. Currently the motor is intercooled with a magnesium 1271, and our goal is to retain the intercooler and possibly trade the blower for a polished aluminum one. For ignition we have a MSD pro-mag or a vertex mag.
So given the parts we have to work with what motor would you use? Our goal is a driveable pump gas motor that can cruise 20-30 miles and still run north of a 100 when we want to have a little fun. Can we use the mechanical enderle injection? How do you plum the fuel system when the boat has 2 saddle tanks?
Sorry for the long post, but I know the experts on here can point us in the right direction.
