Keith,

You must understand that those numbers were on an engine dyono on a stand, those are flywheel numbers. Typically, you will suffer 15 to 18% loss thruogh the drive trains and it sounds like the 1:1 ratio for the RG may suffer some loss too. I don't think the car was ever chassis dynoe'd though.

Don't forget you've got dual 4 barrels there which could probably use a thorough going through. The car sat more than it was driven the last two years or so.

I don't know what Fred did to prep it prior to the sale r what you have done thus far, but I would start with a thorugh tune of the engine and carbs, find the sweet timing spot, get those carbs tweaked and then leave them alone.
