291 Block w/ RJC Girdle

[psiedv6]

Here is a naturally aspirated 4.1 Buick V6 Block w/ 25514291 (the good one) casting that was sonic checked and bored to a 4.000 bore. Also has a RJC Girdle that is installed with ARP studs. It will need to be finished machined to your specks and combo.

This is a good set up for a Turbo Buick to get more turq and power with less boost.

If you run a stock stroke crank 3.400 with this bore, cubic inch will be 256 ci

If you run a stroker crank of 3.625 with this bore, cubic inch will be 273 ci

Bidding starts at $750 plus shipping

Would you be willing to trade for parts or new tire/ wheel combinations ? Very interested-Matt 347-680-8642. Some of the other stuff I have is a complete drysump system, new injectors much more.

The only thing I need right now is a on-center intake for production style heads.

4.1 girdled

Interested, Just a few questions
Is the bore exactly 4.00" and for chromoly rings
Is the line bore untouched
How is the deck height
Is the girdle fitted(shimmed) and ready to run
Is there a oil pick-up extension included or can this be purchased from Jason
Sorry for all questions, but my block is kinda beat-up and don't want another one like it. You can pm me with details if needed, thanks Ken

Does it have stock or billet caps? When it is sonically checked does that include magging it for any hairline cracks?

Sorry for the delay in responding, I don't come on here to much anymore.

This was going to be for my dads car, but he is selling his car and will not need this anymore, so this block was never finished completely.

The sonic, bore and girdle was done by Cook Racing machine in Long Beach Ca. (not open to public).

The block has stock caps and the block was standard bore and never had any boost to it before it was dropped off.

The bore is net 4.00" and was never finished honed for any clearances

If you need more pictures, let me know, I will have to move a few blocks to get to it.
