Thread: weight of a 400 long block

Tweet

i need to know the weight of a 400 long block

Well, a sbc weighs about 575 complete, so maybe 450?


Don

No Denny, I might be wrong, but that 575 weight is for a complete engine. If you take of everything but the block and heads it should be about 125 lighter (a guess). I order the replacement long blocks at work for marine repowers, and on a pallet the long block comes in at 525, including the pallet and crate.

The website is a little confusing because he includes both complete and longblocks in the chart, but doesn't really specify which is which.

Don

A long block is a short block with heads installed. No intake, carb, exhaust manifolds, distributor, pulleys, accessories, flywheel or flexplate, etc. A short block is the block with crank , pistons, rods, cam, timing chain, oil pump and maybe a pan

There is no denying you really know your stuff, and I think you and I are saying the same thing, only calling it a different name? But in all things mechanical, I always defer to your opinion, because I have come to respect it.


Don

Yeah, I knew that you and I were coming from pretty much the same place, and like I said, your knowledge is always impressive.

That's where I'm confused a little. That's why I just posted those links, and figured he may ask more, or say that is what he wanted. Usually, a fully loaded one with all the goodies runs a little over 600 pounds. The type of heads, and intake is a factor also. I wasn't going against what you said at all. Just adding info.

Where is he ??

I have just one question.Why does he want to know the weight of a long block and he also want's to know about the 624 cylinder heads?Am I reading to much into this?

Maybe he's shipping one someplace.

Then he brings up the 624 heads.
I did not see that one coming.

You mean the box for hauling around the 624 heads in the back of his truck?

Yes we are known for it.
Sometimes I like to fight with myself and I have never lost yet.
