Is it going on the stock 1970 Pontiac engine with no modifications?

Even if it was it's too lean on this new fuel with the stock jets/metering rods.  Call the shop if you need a better calibration and rebuild kit to get it up to par for this new fuel and calibrated for what you are going to use it on......tks....Cliff
