Yeah, thats what I was thinking about more so than the stroker option. The broader range of lengths available for the BBC(up to +.300 longer than stock 235/261 rod) will also allow for a more common SBC forged piston that could be massaged a little to be made to fit the application without too terrible of an extra expense. Unfortunately for the GMC, the BBC rod choice will only be an extra +.100 longer than the stock GMC rod, so it doesn't really give you the same benefits for that engine group as it does the 235/261 engines! Maybe using the shorter deck 248 engine block bored to 4.000", along with the 270/302 crank and BBC rod im using could get you closer to a more common SBC piston. The 270/302 blocks have such a tall deck height, there just isn't much option for a budget rod and piston swap....
