Technical Common Engine Swap Dimensions

I came across this chart while looking up how to shove 10lbs of Mopar engine in a 5lb bag of 1960 Ford Falcon. Hopefully it's not a duplicate post. I'd love to have had this info before I started the project, because I didn't realize that an LA was not much bigger than a 144inch Ford 6. Less would have been cut out, lol.

It would be great if people could add their actual measured results for common mods to these engines, such as:

1. Flathead/SBC/SBM/Hemi/Yblock/etc. with specific aluminum intakes subtract X lbs, but alloy intake AND alloy heads subtract X/Y lbs...

2. Mopar long rams add X inches to width...Eddy Myer's intake adds X inches to height...Rat Roaster intake adds X inches,

3. 4-71, 6-71 adds X inchs High, Y inches long, Zlbs when using Q intake....

The problem with any chart showing engine sizes, is that it doesn't really provide a complete 3d model of the engine, and all it's extremities.

 

Part of the reason mechanics hate engineers just because it will fit doesn’t mean you can actually work on it without removing most if not all accessories or entire unit

 

Torch and a sledgehammer anything will fit.

 

True enough, if your the engineer of the job you got nobody to blame but yourself when it comes time to repair

 

There’s some interesting figures there. You wouldn’t have thought the big Caddy would only be 25lbs heavier than a SBC or that a 429/460 is that much heavier than an FE.

 

Or that a 351W is the same width as a 302. Reader beware.

 

Those caddys are big, but pretty hollow....i had an early 472 with the good compression in an 81 buick regal back in the early 90s....first gear was just useless.

I'm pretty sure a ford 300 is more than 1 inch longer than a falcon 6

 

probably depends where you measure it, eh? which is the problem with these charts

 

As with any such charts, the information they contain needs to be mixed in with previous personal knowledge and observations of other known experts. I've yet to see a casting number chart for small block Chevrolet V8s that didn't contain obvious (to me, anyway) errors; cylinder heads being listed as used from 1957-62, when the valve cover bolt configuration changed in late '59.
