    I can tell you the LS3 all aluminum 427 is 550 lbs shipping weight. Our aluminum headed 540 bbc BluePrint's block is 615.

          they found 440 pounds of stuff to put on the block?

          Somebody have a 454 block to weigh? I bet it's a helluva lot more than 105 pounds. I'm not making up the block weights, somebody else is.

          I'm getting at or over 200 pounds for BBC block from numerous sources, 105 pounds for the LS2 block. The LSX block is supposed 225... no damn wonder they will tolerate a couple thousand hp.

          I'm out of this thread - the only thing I was trying to do was ASK have you thought about a 6.2 aluminum L92/LS3, the Cadillacs used aluminum 6.2's and it would be lighter. Jeeeezus.

          • and again I'll say - it costs roughly $3000 less to build a BBC AND the weight difference is nominal



            LS 427 - 12k
            http://www.ebay.com/itm/CHEVY-427-LS...386939&vxp=mtr

            SBC 427 - $8700
            http://www.ebay.com/itm/CHEVY-TURN-K...8259bb&vxp=mtr

            BBC 427 - $4500
            http://www.ebay.com/itm/Chevy-427-49...41102482629%26

            Cadillac 6.2 - $6500
            http://www.ebay.com/itm/10-11-12-13-...5325a6&vxp=mtr


            of course, the 427 motors have about 200 more hp.... so why would I put a substantially lower hp motor in the car when it costs more money than the option I'm going with?

              The forged BBC crank isn't exactly a feather weight. DG learned how much lighter the sbc 400 block without the rotating assembly in it.

              • This one makes more torque at 2700 rpm than our LS 427 does at it's peak. Although, we will skip the mpg comparison. Just don't look at the picture. One of my work projects is getting new pics of all the engines. These are the two engines I was comparing the shipping weights.

                      I like that a lot more than I thought I would!

                      • what's really amazing is how the car is so rigid that it can balance on two buckets

                              they paid big bucks for that effect - it's the latest thing, where some cars look like the just came out of the shop, and others look like they need to go in - the latest, greatest show cars look like they're still in the shop.

                              That's an LS powered car - but maybe you didn't get the memo - I overruled Beags and am going with a BBC 427

                              • You keep it up and the Healey trade will end up even....I won't even ask for any boot money. Now a big-block - this just gets better and better.
