The block is a iron block at 4.280 bore and 4.250 stroke. The heads flow 320 intake @ .650 lift and exhaust 250@ .650 lift. The compression is 12 to 1 and run on VP12 fuel. The engine will have no problem running hot with the proper cooling system and fuel. I did not dyno with a dual plane intake but from past projects I fell it would have hurt the HP about 25 on the top end and helped the tourqe about 20ft/lbs. We are doing a 496 in a Shelby block with a solid roller and about 11.5 to1 and a single plane intake that should be interesting. A engine similiar to this but with a dual plane intake , hydlaulic roller and steel crank with 427CI would be about 13,000.00 to 14,000.00 . The crank used in this engine was a Scat cast steel crank with the 2.200 rod journals and we used a 6.800 long rod with the .990 pin. They were also from Scat. The pistons were a custom JE which is what we have used in all of these FE's, The DaVinci carbs we are using are HP950's. I have talked to him about installing power valves and when you do this you have to jet down about 6 to 7 jet sizes. This makes the car idle better and works better on the street. I told him we were using these on street strip vehicles and now we have them working pretty well. I will try to get some of the dyno pulls posted with more in formation. Thanks intake
