weighed my 300 engine today..

Post #1 by ivonius » Sun Mar 22, 2009 10:21 pm

...for the long block: with flywheel, valve cover and oil pan in place, but with NO crank dampener, no manifolds, no starter, no generator, no ps pump, etc.: 420 lbs!!! This was a real surprise seeing as my boat-anchor of a 4-cylinder (2.2 liter) that I am replacing in my Triumph TR4 weighs 400 lbs dressed the same way. So going from 2.2 L to 4.9 L is only costing 20 lbs. And if I put in a lightweight flywheel (say, 20 lb vs the stock 30), a lighter starter (say 14 lbs vs TR 19) and tube headers vs TR 13 lb cast, we get to almost break even. --Good times ahead.
PS. It's a 1993 EFI I bought from a salvage yard this week. Pulled off a bazillion lbs. of stuff to get to the essential engine. Now where is a good T5 Mustang 5.0L trans?

A whole mustang t5 donor car would be nice, to get all the pieces.
Are you swapping the stock rear for an 8.8?

That's really interesting to know! I know there's been a lot of debate over the years as to the actual weight of the engine.

As far as I know, a 289/302 complete, weighs about 550 lbs.

Weights are always a bit edgy to quote, but I think the 289/302 is closer to 450-470lbs. The 351W with factory iron manifolds is around 550-560. Now a nice 302/347" SBF with aluminum heads & intake, lightweight starter, and short headers would be in the same weight range as the 2.2L Triumph or the 300" six, maybe even lighter, and definitely shorter than the BB6.

I had two guys from the engine shop lift my empty 240 block from ground level and set it in my Subaru. I couldn't believe it!

Guessing the block alone is less than 300 lbs. Head is big time heavy, about 50 lbs, and crank is a good 30 lbs or more.

Hmmm a nice alum alloy head...wherefore art thou...

Mmmmmmmm......... it's a good deal LESS than that. I have lifted bare 300 blocks several times into a pickup bed by myself and didn't consider it to be any heroic feat. Take the crank, cam and piston/rod assemblies out and there really isn't much left on a thin-wall casting. Wouldn't want to try it with a 262 block though :shock: Or my International 240 Silver Diamond Six :lol:

My dad seemed concerned when Dakota put the 300 EFI block in the back of the truck. I've been dragging that thing out whenever I get the chance to just to observe it. The log head has to weigh nearly as much as the bare block.

Ford Performance quotes a Boss 302 iron block with aluminum heads, no flywheel, no intake and exhaust manifolds as 560 lbs. which is right in line with a smallblock chevy at 550 lbs in the same configuration. It's not till you get to the aluminum block coyote motors that you get below 500, and they're still 470.

I am glad to see the 420 lb confirmed weight for the longblock 300. Now if they can get that 300 aluminum head project into production I'll be a happy camper.

seen that chart B4. Many say it conflicts w/reality and quote different numbers. I, on the other hand have no proof but do watch these things as they go by...
