I did some digging through my stash and I am going with the blown big block out of this Revell Corvette:
I am going to do my best to replicate that crazy Dobbertin motor, I have the air cleaners from the AMT '70 Superbee. I'll also be using the wheels and tires from that kit. I have no idea where I'm going to get the Turbos. I may have to make them. I also need a separate, big block, chromed oil pan to go on the 'Vette motor.
Tonight's project will be extending the firewall so it meets the cowl and cutting the doors free of the body.
