here ya go, this is out of 'The hotrodders bible' it's a good book, also have length width ect if you want that stuff i could edit it in. Sbc 535 bbc 635 chvy 6 415 flathead 525 sbf 460-550 bbf 650 hemi 690 olds v8 620 poncho v8 650 nailhead 630 caddy 625
A Chevy 216/235/261 is closer to 650 lbs, I forget where I looked it up but someone wanted to know if he needed heavier springs to run a 331 in an early 50's Chevy and I discovered they're pretty close weight wise.
Big block Mopar is around 630 lbs. Everybody told me I was weighing my car down with the 383 over the 272 Y Block...I saved 20 lbs!
Dave Williams's web site is full of info such as engine weights. http://www.bacomatic.org/~dw/index.htm
Weights according to Hot Heads, Factory Hemi original With acc. Chr 331/354 697 lb, 392 737lb, low deck DeSoto 631lb Hi deck 669 lb, low deck Dodge 577 lb, high deck 611 lb, SBC 528 lb, BBC 693 lb
I have a hard time believing that a SBC is 10 pounds heavier than a flathead.... isn't a flathead more like 700?
hate to cut in but could you give me the sizes of a Hemi ,caddy 390 and buick nailhead 401 relative to a sbc ..........Marq
The list i have only lists the 472-500 caddys, and i'm not 100% sure about the wieghts, like i said i got them from a book.
just goes to show you that a dressed sbc with aluminum heads, intake and water pump is the most power per pound out of all the common motors.
who really cares about pound for pound ,weight to horse power ratio, if youve seen one sbc youve seen 1000, with the hemi you' get the WOW effect.......dont get me wrong i love the sbc.have had some killer motors ....
I went to those websites listed--the 348/409 engines weighed between 620 and 655lbs. Can anyone account for the differences? The only differences I can think of would be a cast iron single 4bbl vs the aluminum single 1x4, cast iron 3x2 intake and the aluminum 2x4. When they were introduced, they came with a generator, but received the alternator by the end of the series. Anyone have an idea if they weighed them with accessories? And a flywheel vs. a flex plate would also make a huge difference. Either way, it's heavier than an iron head small block, but a lot lighter than a big block Chevy. One of the things the SBC was known for when it first came out was its relative light weight, especially when compared to other OHV engines of the time. -Brad
The above website lists the 8BA at 569 pounds. The 302/5.0 Fords are listed between 411 & 460. I should be fairly easy to build a 5.0 with aluminum heads and intake that would be in the high 300 pound range!! -- Chuck
Taller deck height to accomodate a longer stroke? It's the same reason that the 350, 361, 383 and 400 mopars weigh less than the 413, 426 wedge and 440
No way ... flathead heads have a lot less iron to them. You can pretty much carry one in each hand like it's nothing. Then add in the fact that it has no pushrods or rocker arms.
I can't be much help for those looking at V8s, but if you ever wondered how much a Buick I8 weighed - it's in the 750#+/- ballpark. The only reason I held onto this stat was because it was far heavier than the "elephant" motors....making it even fatter than the elephant - and leaving me wanting to come up with a proper nick-name.... But I digress.
If you're looking for pound per hp, look at the Buick smallblock. The Buick 350 is abt 450lbs, 230hp and 350ft/lbs of torque. This is with a 2GC carb. IHC SV series V8's are around 700lbs I thought the Ford 302 won the pound per hp contests with the Boss motors. Are we talking about complete motors with all acessories or longblocks? Aluminum or iron parts? Shawn
I would agree to this,and warn anyone using a modern engine hoist,to shorten the boom as much as possible.These engines,especially with trans attached,will STRESS TEST your engine hoist!!!
