I like the dykes but they dont last a long time. I would like to try a .031" dykes hellfire type ring with the gold finish face coating (PVD 92) from Total Seal

400 Gm block, GM nodular crank, GM camel hump heads with no intake runner porting but are bowl ported and exhaust runners polished, vic jr, solid flat tappet, flat tops with 1/16" 1/16" 3/16" rings

The engine break away torque was 17 or 18 foot pounds, constant was 14 foot pounds. The engine seals up great, making about 520-530hp my ET's. Over 250 runs without .001" change in lash with 160 seat and 400 open on std crane solid lifters. Switched to alky when he bought a dragster and left the team with the engine,,, has went as fast as 8.60/.8.70's consistently

He wanted me to maybe rebuild the engine, pulled the pan off and called me. Engine looks like new. Gets no alky in oil, rings gapped .022" / .030"+
