Title: 541 cubic inch FE drag and drive
Post by: CaptCobrajet on October 14, 2025, 11:00:59 AM

1016 hp at 7700 rpm.  805 ft lbs torque at 5500 rpm.  It has 990+ horsepower for 1700 rpm up top.  Four digit power from 7000 rpm to 8200 rpm.  Shelby big bore block, Losito billet heads with a little love and valve job here.  4.500 Crower crank, CP pistons.  Dual three circuit 1050 Dominators.  We cammed it for making the Drag Week drive.  I think this engine would make 1100 hp with a 1-inch lift cam, but it wouldn’t make the street miles like that.  Pretty good like it is. I think my son is going to put it on our Facebook page and uTube when he gets the opportunity.

You should probably put the big camshaft in, put it back on the dyno, just because....

On second thought never mind.  That's a very cool build.

Dumb. How about a round about on the camshaft, less than 750 lift?
