The fact that it posted such good low-end numbers is what makes this a great piece. Many others have tried to run small blocks in place of bb and have sacrificed low-end torque for high horsepower numbers. thats where they fail. Trying to move a heavy tub of fiberglass needs torque not hp.
With all the newer kits to get big cube smallblocks plus lighter more efficient hulls you can expect a lot more of these packages to be appearing in the future. LSX, etc. The SB2 stuff is pretty wicked!

So I was right about the toque. Looks like small blocks might be the way to go in the future. From what I saw I did not see a down side and it appears I was right for a change Thanks

crockett, are the heads aluminum and if so couldn't you run the compression to over 10 to 1. especailly running the water as cold has it was on the dyno. i noticed the water temp was only around 120 F. did you try running at normal car temp like 180 or 190 to see if it made more HP??

Yes they are aluminum heads. I wanted to keep the comp down so I had a safety factor for pump fuel. If the customer goes somewere and they have 89 octane he can run it and the HP difference between 9.4 and 10 to1 is hardly nothing. I build the clearances in the engine to run cold and we make more power. If you heat soak all those aluminum parts heads, intake to 180 to 190 the air temp going into the engine you are losing more power. Every 10 degree's is 1% HP

I have not yet have a cost because Furniture Row gave me all the parts accept the Dart Block, Diamond Pistons, Total Seal rings, Trend pushrods. We made intake and valley pan spacers and also had a new oil pan built for the Dart block. Furniture Row has 46 SB2 engines and parts left over.I was down in Charlotte, NC and was at Hendricks and they also have several SB2 parts left over. I had Inconel ex valves made to go in the heads also and used their Titainium intake valve. I used all their Jesel valve train also.

crockett, your statement about hp loss on aluminum heads, do think it applies to steel heads as well??
just wondering, we did some dyno testing on a spec stock type race motor and loss hp the colder it we got it below 180.
