    This is going to be an odd sales add, so bare with me.

    I am posting my 350 Buick short block for sale, I have most of the parts to finish this engine but do not want to sell any of the others parts until the short block is gone.

    This engine was a pet project of mine and I have a stupid amount of time into it, I am going to post some of the highlights and if you are seriously interested in it send me a PM and we can set up a time to talk on the phone. There is probably to much done to list, and if someone is interested they could buy just the short block, or all the parts which includes a pretty nice set of iron heads, roller rockers, a custom deep sump pan with a pretty cool windage tray, and some other stuff.

    The short block is a stock 350 block with all the oiling mods done, main studs with straps on the main caps, a short fill, and the whole block has been deburred.

    The crank has been hand profiled, the mains were index ground .010 and the rods were offset ground to 1.880 to run the race Honda rod bearing. It has also been internally balanced with Mallory slugs added to the counterweights.

    It has a set of Eagle rods in it, and a set of .080 over Chevy 283 Ross pistons in it with valve reliefs cut for the Buick head. (.030 over STD Buick Bore)

    It has a pretty big solid flat tappet cam

    Intake .638 lift and 268 Duration @.050
    Exhaust .618 lift and 274 Duration @ .050

    It currently has a billet double roller timing chain, a front cover with all the oiling mods done and an oil pump set up on it, and Aluminum shell ATI balancer

    This covers most of the stuff, this motor would make someone a pretty cool race engine or be a very rowdy street engine. I was going to spray it with a 200 shot, so the internals were picked and set up with that in mind.

    If you have any questions feel free to ask, it is located in St. Louis MO. All work was done at AMT Performance who has been in business for over 30 years and has build 9 Sec Buicks. If someone want to make a deal they can buy this, all the other parts, and have them finish the engine. If no one is interested I am going to take it to a long block and see what happens.

    I am asking $3000.00 for the short block, that would not even cover the labor to duplicate this.

    My race car is set up for an LS platform, and my Dads Buick is set up for BBB. This does not really have a home in any of my current cars.

    I would consider trading for race BBB parts or LS3 stuff.

    Great Questions. It is 362 Cubes, and the pistons are at 0 deck.

    This would be a killer with the new aluminum heads that TA is eventually putting out. Good luck with the sale. If I didn't have so much invested in my 455 swap, this would be something to entertain!

    What year is the block? Sorry if these are dumb questions, I am not very well educated on the 350 but aren't `72 and earlier heads not able to be bolted onto a `73 or newer block? Also, I don't know what chamber size is on stock heads but what would the compression ratio be with a stock iron head for a compatible year?

    If I remember correctly it's a 68 or 69 block, but all the oil mods have been done. You can put newer heads on the older block, you just have to block off two water ports in the head.

    Depending on gaskets and the final CC on the heads it would probably end up around 12.5 to 1

    Your numbers aren't adding up.

    Sbc 283 has a standard bore of 3.875", now if you add another .080" to that you get 3.955" bore, not 3.830" which is a .030" over standard sbb 350 bore.

    With a 3.955" bore and a stroked crank to 3.940" you would be @ 387.229 CID, not 362 cubes. Even if the crank was de-stroked for the 1.889" rods to 3.760" it would have 369.539 cubes.

    Not trying to knock you, just wondering what you are really trying to sell?

    Also I notice that the cam isn't installed in the pics, is that because of cam to rod clearance issues? Have the rods been clearanced for that huge cam?

    That's actually a really good catch. I misspoke, they are .080 over 265 pistons, not 283 pistons.

    The camshaft is installed and the rods have been clearanced for the camshaft.

    Nice deal if you want to go fast. Substitute a roller cam and you'll be pretty much bullet proof.
    Like the O.P. says, lots of blueprinting. The work is already done for you......

    It'd be a killer with well ported / setup iron heads.

    That cam with those cubes and that compression will sound wild
