I assume you mean their SBC race block? They are coming out with an all new Ford block too to take on DART and Ford that has extra head bolts on it and some head companies already have heads for it!

I've used the World blocks and they have done great so far. I have one at 4.185 bore that Danno on here helped me with that is running in the 8s on NOS and has won quite a few 10.5 races down here and it is holding up very well!

I get a good deal on them but DART has nice stuff as well. There are little things about all the different blocks that are good and bad. One nice thing about the Worlds's is also that you can drop a 4.000 crank right in with no clearancing even with some bigger rods and minimal clearancing even with big aluminum rods depending on the shape. Of course the Rocket style blocks are even better.

Also dirtnap the line hone was on the chevy high so we tightened it up a little and ran the line hone through a few times to get back to about the middle but it probably would have ran fine anyway as they were all uniform and round.

Any of the World, Dart and Bow-tie blocks we have checked have been very close to blue print.

We do all our work on a 4-axis Haas CNC machining center and we can probe the the blocks for cylinder location, cylinder size, deck heights and it compares it to the blue print and the blocks I have metioned seem to be pretty good.

The older Bow-ties use to have some lifter bore placement problems, But GM has corrected that in the last few months and has changed the way the lifter bores are machined they are not done with gang tooling any more.
