FYI i have an A 460 block i would sell.it has 2.750 mains,4.420 bore.and 2 .100 sleeves in 6 and 7.it also has really thick cylinders,up to .300 thick at current bore.i would sell it for $2500.or with the crower 4.400 stroke for an extra $1,000.
youmay make 1500-1800 with the stock block but you wont have peace of mind for long.

it would be in a street stripe machine mainly stripe but more detuned for street.
i am not saying i want a cheap block to make the power i am trying to work with what i can get ., afterm,arket blocks are hard to come by.
why does your a460 have 2.75 mains? i thought they run 3.0 bearings? 4.4 stroke crank that is a differant stroke probably a oddball length rod and or custom pistons for that application?
well i would be building the engine from ground up so probably go aluminum rods or a really good i beam rod and forged if not billet crank as well.
if you were closer i might consider the block but i am in canada.
thanks

^ I looked at his deal. Seemed Like a Molar 6.750" Rod worked with a shelf piston or was very close with a little Decking.

Early 2.75" Main SVO Blocks are pretty Cool to Me. They have advantages in my Opinion.

Lighter Crankshaft.

Cleveland Main Diameter, I Don't Know if Cleveland Racing Bearings Interchange but, Maybe? I guess less bearing drag and better oiling. Not positive but, something along those lines, and better for High RPM, I think.

Folks Complained about 429/460 Mains being Too Big and Not Good for Racing. Probably More BS, then anything.

Besides bearing journal surface speed the biggest advantage is less oil throw=off into the windage of the crankcase.

btw do you have any 4 bolt main caps too sell? i cannot find them anywhere .?
thanks
Aw man, I literally sold fifteen sets of 4-bolt billet main caps over the last two weeks. Those sets that remain are earmarked to be fitted to blocks, some of which are already pre-sold themselves. I am out of the shop for a few days and upon my return will reassess what I may or may not have available and let you know—I need to make sure I am able to fill block the orders.

youmay make 1500-1800 with the stock block but you wont have peace of mind for long.

it would be in a street stripe machine mainly stripe but more detuned for street.
