Well, it would work, the question is would you like it? Cuz it's the torque values we should be comparing, I think. I think it would work but you may find yourself using higher rpms through the gears to get going. Eh, maybe, maybe not.
I recall back in the day we discussed these cars; I like the Speedster kits and you like the 550s, but given the chance I'd be happy with either!
