Anybody know where I can find one of these? Up here in the hills all the dirt track guys buy them up. So i cant seem to find one.
Im looking for a stock longblock to rebuild for college next semster. It has to be complete to the heads, i don't need the accessories or the intake/carb. I live in western maryland. The closer the better as I'll have to borrow a truck or pay for gas which in turn will really cut into my budget. Thanks Blyth |

400s weigh more than 350s - when I replaced my 355 with a 406 my 79 Z's front end dropped down to the top of the front tires. I had good clearance with the 355 before swapping engines. I think the extra weight comes from the crankshaft and maybe the block itself. If you use aluminum cylinder heads that will reduce the 400's overall weight. Just bear in mind that your front/rear balance will be upset by using the 400 or 383.

QUOTE (Rob Hood @ Oct 2 2006, 12:13 AM)  400s weigh more than 350s If they do weigh more (and I'm very skeptical) then it won't be by much at all. I've swapped in a few 400s and never have noticed anything. The crank is within a few pounds and if the block has more material somewhere, just remember the eight big holes are even bigger. I have a complete 406 sbc short block and a complete 355 long block that I'll be taking the intake/heads off of this week...I'll weigh both of them as short blocks and post back as it has me wondering now. Anyone have hard numbers on 400 block weight vs 350 block weight and then crank weights? curious... Costas cars and such... |
