Engine Dimensions for Popular Swaps
Ever since the first hot rodder dumped his Model A’s four-banger for a flathead V8, engine swaps have been a proven way to get the extra horsepower your customers crave.
There are several engine swap kits for
putting non-stock engines into popular body styles, such as big blocks, into
1955-'57 Chevys or small blocks into Jeep CJs, for example. The kits
usually include things like motor mounts and headers designed to provide clearance of the vehicle frame, steering shafts, and the like.
Since there’s more to engine swaps than just squeezing the engine
under the hood, Summit Racing has come up with a list of things to measure and check
for to help you perform a successful horsepower transplant. Remember,
measure twice, cut once, and start swappin’!

Engine Swap Check List
1. Always check
measurements with all engine accessories installed. That will help
prevent catastrophes like bolting in an engine and finding you have a
half-inch of radiator clearance.
2. Select the engine mounting method
(rubber mounts, solid mounts, motor plate, etc.) before installation.
The mounts used can affect clearances, especially height.
3. Double-check – make that triple-check – hood clearance, firewall clearance, and fan-to-radiator clearance.
4. Make sure driveline angle is correct. You (or the installer) may have to adjust engine location in the car to get the proper angle.
