305 Stocker Block Question

[Jeremy K]

I am looking for some advice on what direction to go regarding a block for my 305 Camaro. The bore is 3.800" and I'm currently using a 1980 305 block filled with HardBlok. Is this common?

How about sleeving down a 350 block? What sleeves would I use? Particularly brand and part number?

Any other options?

I'm not having any trouble, but I'm just wondering if there's better options.

I will appreciate any help given. Thanks,

Jeremy

Jeremy, I've used the stock 305 block with grout on all my 305 stocker stuff, never had a problem. Get a block with a minimal amount of core shift as possible, prep it and race.

It was highly recomended to me to sleeve a 350 block , we have been happy with it don't know part #s .---Trevor

You could use Melling thick wall diesel sleeves in a 010 350 block if you wanted to. If needed, I can probably get you a part number.

I would say the filled 305 block would be quite a bit lighter than a sleeved 350 block, especially on that end. They will live, and plentiful as 350's. I only turn 7200 but my block is now 6yrs old, after filling.

Thanks for the replies so far.

Trevor (or anyone else): Do you happen to know the weight of your sleeved block?

Alan: If you really don't mind, could you provide a part number for a sleeve that would work in this situation. I can browse catalogs myself, but thought that someone with experience in doing this very thing could point me in the right direction. Thanks.

I know I have to consider the extra water, but I thought that there was a possibility for weight savings with a sleeved block. Maybe not. Again, no problems with my filled 305 block with 2 years on it so far, just looking at other options.

the sleeve job would cost a ton...

305 Small Bore SHP Block

Limited quantities are available of a 305 small bore version of Dart’s SHP block. These blocks are intended to give racers in classes that require stock displacement the option of utilizing a high performance block.

True, it adds about $800 to $1000 to the cost of a block. However, a filled 350 block with diesel sleeves would be as close to the Dart block Bub speaks of, as close as you can get without buying the Dart.

I wasn't too worried , about the extra weight as it's in the right place, prolly about the same as a 305 with hardblok or an aftermarket block.
