    Can anyone tell me the best place to get a 350 block with a 1 pc rear main seal. I found this one from SDPC

    http://www.sdpc2000.com/cart.asp?action=prod_detail&catid=244&pid=133

    I'm looking for just the block, either new or bored .030 over prepped and ready to be put together.

    FYI: Building a 383 and don't want to have my truck down while I machine the stock block /forums/images/graemlins/thumb.gif

    mmmmmmmmmmm. RamJet

    have you tried calling up your friendly local chevrolet dealership?


    10105123 350ci Bare Block
    This engine block is used in 1986-99 Gen I heavy-duty applications. It has 4.00" diameter cylinder bores and four-bolt main bearing caps. This block is machined for a one-piece rear crankshaft seal. (Does not include rear seal or adaptor.) These blocks weigh 181lbs.

    Technical Notes: Cylinder wall thickness is the same as current production engines. The lifter valley is machined for hydraulic roller and flat tappets. Crankshafts with two-piece seals can be installed with adapter P/N 10051118. (Block casting P/N 10243880 or 14093638.)


    or

    What a great starting point to build your own hot rod 383 engine. The only major items you will need to complete your engine are cam, lifters, cylinder heads, and manifold.

    This 383 ci partial engine is used on all 383 crate engines.


    The partial engine includes the following items:


    P/N 88959106 - Block, 383 stroker after machining - Q/P 1
    P/N 12489436 - Crankshaft, 383 stroker - Q/P 1
    P/N 10120990 - Bearing standard front & intermediate - Q/P 4
    P/N 10120993 - Bearing standard rear - Q/P 1
    P/N 12523924 - Bearing standard connecting rod - Q/P 8
    P/N 14088784 - Sprocket, crankshaft - Q/P 1
    P/N 14088765 - Flexplate assembly - Q/P 1
    P/N 12497624 - Rod, connecting single 383 - Q/P 8
    P/N 12489437 - Piston & pin assembly standard 383 - Q/P 8
    P/N 12522848 - Ring set standard 383 stroker - Q/P 8
    P/N 12555283 - Pump assembly, oil - Q/P 1
    P/N 12550042 - Pump assembly (screen) - Q/P 1
    P/N 3764552 - Shaft, oil pump drive - Q/P 1
    P/N 12557558 - Pan assembly, oil - Q/P 1
    P/N 10108676 - Gasket, oil pan - Q/P 1
    P/N 12562818 - Cover, front timing (plastic)- Q/P 1
    P/N 12498008 - Balancer - Q/P 1


    The partial engine does not include camshaft, lifters, timing chain or cam sprocket. The oil pan is loosely assembled on the block. So it can be disassembled without destroying the pan gasket.

    The 10105123 is the one I have linked above for $624.

    The 383 (12498332) is a nice peice but at over $3,000 I'd rather build it myself.

    I've talked to a couple engine shops and all they have is 2 pc seal blocks. I thought some machine shop on the net would sell blocks that have been bored and cleaned already.

    Can't vouch for these guys, but they are in the same town as me. 350's

    When I last looked at 4 bolt 350 1 piece roller motors, I was pretty amazed at the cost there.

    They must be some sort of "network" as I found a couple other websites with the same layout, and I suspect the same prices, but I didn't look closely.

    Just something to consider. I don't think you get ripped off going with the dealer on blocks, but I think you can typically do it for a bit cheaper.

    call up all the chevrolet/gmc dealerships around your area. you'd be supprised. thier prieces might be a little higher than sdpc, but consider the cost of shipping, or if you want to drive to BFE, i mean Lubbock, thats alot in gas. if a dealer can get you the same block without having to pay shipping, then you can just pick it up. i called around here, and found L31 Vortec heads that were a little higher than sdpc, but with shiping, the dealer was better.

    You are still talking about dealer prices. Look at GM's markup, and see how much we get raped by them. GMpartsdirect makes their money off of shipping and handling, SDPC offers it as low as possible to still make money, and the local dealer charges you full retail.

    If I could buy everything from aftermarket companies, with the same quality that GM parts used to be, I would never think to go to the dealer. As it is, some things are still better bought at the dealer. But if GM makes the block anyway, it doesn't matter who you buy it from, as long as you can get the best price possible.

    IIRC - you will still have to machine the innards for a 383....

    You will still need to relieve the bottom of the cylinder and cam for that longer stroke. /forums/images/graemlins/blush.gif

    I'd sell you mine...but I am building it up /forums/images/graemlins/tongue.gif

    Seiously though, hit up a yard and get a builder motor...Then sell everything off of it you don't need and you will probably come out of the deal with a free block...

    I have done this with quite a few parts and if you have a place to keep the engine for a while, it works well for getting parts you need CHEAP...

    Sounds like a plan, the hard part (so far) is finding a 1 piece seal block /forums/images/graemlins/thinking.gif

    there are plenty of 1piece RMS blocks...even a Vortec block would work...just call a yard and ask them if the have any 86 and newer 350s that are builders....
