Another excellent engine 101 video from Matt at Irontrap
One of the most popular engine swaps for early hot rodding has to be the early Cadillac OHV engines.
The 331 was first released in 1949 and was used in hot rods almost immediately. The first generation of engines are almost identical and a vast majority of the parts swap between.
Cadillac’s were known for making good power and torque stock and were quite smooth running engines. Speed equipment can be a little expensive, and hard to find at times.
One of the downsides to the engine is the lack of adjustable rockers, but you can use early aftermarket rockers or stock Studebaker rockers.
There are a lot of great articles written in the vintage magazines about swapping an early ford, and plenty of early hot rods and customs for photo reference. Let us know in the comment section below what Hot Rod Engine we should cover in the series next!
