o-ringed block for street use?
forgive me if this is a stupid question...but theres a 454 block for sale nearby, studded mains and heads, bored 60 over, honed, decked and o-ringed. price is right, but i cant find much info about o ringed blocks other than they are used for racing engines, where the heads are pulled often. can blocks with this mod be used without o rings and standard gaskets?
im still planning my 496 build, and wondering if i should consider this block.
thx!

If its the figure 8 type O-ring you could just go with a MLS gasket you should be fine, If its just on the edge of the cylinders you may want to pass.
Should find out what the deck height is befor you buy it also what size the bore is exactly.

Clearance issues (e.g.- power brake booster) with engine compartment components can be a problem when removing/installing the heads with the engine still in the car with head studs. Also, head removal with studs can be a little bit more difficult with because there is no way to get lateral movement to shear the gasket if it is stuck hard. That's just my own experience. Not speaking for everybody. Personally, I like head studs.

I have never heard of a 454 that wouldnt go .060".
Is this possibly just a late model block thing?

60 over? Run, don't walk away. You'll need to bore it again. You can build a 700 hp engine with a 2-bolt main that will hold up just fine. There's lots of those around here for $200.

Its alays one cylinder which is bad making the block not useable for a performance build.
That why I take the time sonic test every OEM block that comes through the door.

thx everyone, sounds like this block isnt for me - heck without gettin technical i think toms point about pullin the heads w studs is a biggie, as i have power brakes.
also, sounds like i should look for a later block vs an older one. blockman i know its meaningless without checking each individual block, but is there a rule of thumb for whats generally the oldest bock i should look for?
also, if 'most' blocks can only go 60 over, why are folks building 496s' off the bat? why not go 489 which i believe is 30 over and save a bore for the future?
thx!
