I guess a simple definition of hot rodding is to cleverly select some existing parts, ideally secondhand, and assemble them into something special in performance or appearance using as little precision engineering as possible.
Max Balchowsky's Ol' Yella would be a great amateur example , beating Ferrari's with often junk components. For mfrs. Pontiac's original GTO was their biggest engine plus lots of production carbs into a mid size car engine bay.
Today hot rodding is very hard as modern engines are highly optimisied and controlled via CAN bus systems which are hard to modify.
Maybe the wave of new hybrids and EV's can give us hope by using " rear end hot rodding", basically installing an electric drivetrain in the back of a FWD car.
Electric motors have two big advantages for hot rodding, Firstly they are so simple they hardly wear out so a second hand one would be fine. Secondly, you can get an electric motor to provide a huge power boost for a short while. An extreme case is an RC helicopter engine half the size of a coke can which gives 7 bhp continuous but gives 14 bhp for 2 seconds. As a hot rod never uses full power for more than , say, 10 seconds that is fine.
Pure EV's use big batteries but mild hybrids have small ones to run just a few miles on pure battery so not to heavy for hot rodding.
If you use two motors then no diif.and the drive shafts to hubs at rear are not too hard. The engineering bit is making the rear hub of an FWD car "live" but even there some models like Golf's and Insignia's which have FWD versions so suitable hubs are available.
So buy a older hot hatch, junk all the gizmos to save weight, mount the electric motor(s )under the boot floor and bolt the battery onto the rear seat pan. Then use some smart young guy/girl to build up the clever bit which is the inverter/controller.
