We plan on upgrading the block in our car and I thought I would ask for input and experiences from the members here. Currently we're running a 74 factory RB block 4.25 stroke .055 overbore Callies crank and rods Diamond pistions 13.5-1 Cam Motion custom grind solid roller aprox .730 lift Out of the box Pro-Comp heads Team G intake with 1250 Dominator in a 3400 Lbs 73 Cuda It has run a best of 9.85@136.mph We knew when we built the engine the stock block would be the weak link and have been fortunate to get two seasons out of this combination by keeping the rpms down and running the car sparingly 200-250 passes the last two years. We've finally got the funds to order the block and tweak a few things in the engine I.E. a jump in compression and some port work. We've looked at the Koleno World and Keith Black blocks. Were going for aluminum for weight savings and repair-ability. Looks like the KB has the most room to grow. I'm also wondering if we should go with the raised cam position? Any input or personal experiences would be greatly appreciated Thanks Randy PS I'm aware of the lack of pickup in the KB block and the absence of fuel pump mounting and factory engine mounts We'll be going with a front motor plate

KB is nice if you can afford it. Picking up a World block from the local dealer is a cost effective way to go but those blocks are heavy.
Once you have a good block you'll be able to pick up a bunch of power by just just changing a few parts. That Team G intake is costing you hp and porting the heads should be good for a bunch.
Andy this car has been a mystery to everyone that sees it run LOL standard bore TeamG intake with a 2" adapter......out of the box Hooker 1-7/8 headers Out of the box Pro-Comps heads Old Mallory unilite distributor!

About every post on blocks here the majority points to the KB. Aluminum is the way to go, and that is my biggest regret; not going aluminum when I had the chance. At about where you are at, you can't get a better weight savings much cheaper than the $$ difference between aluminum and steel.

Has anyone seen the HP Performance block? They were at the nats and looks like a great block!

I have two waiting for me to pick up, one water block and one solid. My solid block was there on display with the raised 55mm cam tunnel, it is for my Dart.
David will make anyone the block in wedge config, he just needs to fill some back orders first. Turn around is about 2 weeks per block.

I'm a naysayer when it comes to N/A motors and aluminum blocks do to the inherit problems on ring seal
I will call you on that one...There have been dyno sessions where they made MORE power with the aluminum block. LMS if I can find it.
