Default New Bare Block

I am looking at building my own replacement engine for my 82 Vette. I am planning on keeping the crossfire system but with some modifications. Currently, I am looking for a reasonbly priced "NEW" 350 bare block. Does anyone know where I can get the best deal (block plus shipping). I was looking at Summit Racing has a GM Performance Parts 350 block with the 1 piece rear main seal (which I think is the correct one for the 82 Vette, correct me if I am wrong here) for $679.50 plus $70 shipping. Thanks for your input.

I think the one piece rear main seal blocks did not show up until
1986.

That is not the correct block...in fact I highly doubt a correct - NEW block would be available, since GM has been using the 1 pc rear main seal since the mid 80's (20 years or so now).

This doesnt meant that block wont work for you, it will even allow you to move up ro a roller cam using factory parts if you wish...I know that PAW sells blocks refurbished to stock dimensions... these are seasoned cores, but are sleeved to factory bore dimensions. What I'm not sure about is if those blocks are available seperately or if they are only an option in one of their engine kits.

To use that block you would have to buy a new crank and flex plate
and a factory crank was was external balance so you would need a
new balancer also . Chevy has new two piece blocks for around the same price if all you are after is a new block and reusing your crank
flexplate and balancer

He said he's looking to build a replacement engine so I would think that block would work fine, since he has to get the rest of the stuff.

Why not just get a rotating assembly?

Check the local GM dealers, but beware-they are ready to screw you on that block just like they will with trying to sell you a car. You can still get a bare two piece seal block- I did about 4 months ago. From my research, you might as well order one from Summit or Jeg's because by the time you deal with the frustration with a parts department at a dealership and then pay taxes, you may only save $30-$50 overall and alot less of a headache in the long run. The new block comes finish honed. Your new pistons may or may not work without getting a hone to fit whatever pistons you use. The Keith Black pistons I am using spec'ed out perfectly. The new block also doesn't come with most of the plugs-buy a Pioneer plug kit also for about $15.

I really have no clue here. But I do know that I'm running an 85 4-bolt block in my 79. It is definitely a 2 piece seal.

Thanks for letting me know about the 2 piece rear main seal. That was actually the one I was talking about but somehow it slipped when I looked it up again. Here is the link for the block I am looking at:

http://store.summitracing.com/partde...5&autoview=sku

And to let you know, I will not be reusing any parts from the old engine because I will pull the engine and transmission and store them. They are working fine, but I don't want to modify them. I figure to build my own 300+ HP motor plus a new 700R transmission, so that I can drive my vette as much and as hard as I want to, without really worrying about the original motor.

I'll check out the part department but if it cost more than getting it from summit, then I would rather get it from them. Again, I don't care about matching casting numbers on the motor as long as it mounts just fine.

Thanks.

Try Scoggin dickey for price at www.sdpc2000.com
If you are going with all new parts I would use the one piece seal
block thats designed for a hydraulic roller. If you want to stay with
the older two piece seal block and flat tappit hydraulic cam chevy has
a crate motor long block thats cheap in price with a three year warranty.

Thanks for the link. Price seems to be about the same as summit. Have to check about shipping. I'll probably go for the one piece seal but not yet for a hydraulic roller. I doubt that my crossfire system can take advantage of the roller cam. Correct me if I am wrong here.

Thanks again for your input.

It can. The crossfire computer is tunable so it shouldn't be too difficult to adjust to it.

Yep, the Targetmaster or whatever it's called now is a complete 4-bolt 350 with 2-piece rear seal. It would have heads that would bolt up a crossfire.

If you want a decent 1-piece rear seal base engine, I think you can still buy the shortblock for an 87-95 truck. That would be a non-roller flattop 2-bolt. The longblock has heads that won't exactly bolt to a crossfire intake.
