528 hemi swap

Yes it's a 440 .030 over with custom Aries pistons that have the pin location in the same as a stock 440 piston and the top of the piston is a Hemi 10.5 to 1 design. With the heads having raised exhaust ports and 2.25 intake valves and 1.90 exhaust valves. I also run 1.6 intake rockers and 1.7 exhaust rocker. With a 484 lift 284 duration cam and a modified street Hemi intake manifold it made 525 ft lbs of torque and 675 hp at 5800 rpms with the cross ram intake and two 770 cfm Holley's it made 545 ft lbs of torque and 735 hp at 6400 rpm's which isn't bad on pump gas.
