it cost me $1300 for the conversion. BUT I cheated. I bought a 71 elcamino project truck without the motor, but with 621 bell housing, pedals, shifter, muncie, console. basically the whole ball of wax except for the driveshaft. Paid 1300 for the elcamino and 20 dollars for the driveshaft. plus 60 for the 454 flywheel.
I could have made the whole conversion basically for free if I would have parted the rest of the elcamino. I ended up with a spare 331 12 bolt posi, discs, SS hood, floor shift tilt, AC. BUt like any car nut would I just went and got it running too. jim
