Speedmaster vs Trick Flow Heads... This is stroker #2 for the comparison. In case you didn't see the last posts, I built two very close 360 LA strokers to compare heads.
Again, this one has a 4 inch cast crank, Lunati Voodoo hydraulic roller cam 20200712lk, Eddy Air gap, 780 pro system carb (using the same carb), Doug's headers, m72hv, hv water pump, Milodon windage tray, both have 10.4 to 1 compression.
This one has Speedmaster CNC ported heads that were bought bare and has new Comp springs, new valves, and 1.6 Harland Sharps. It has IC9978 pistons with negative .012 height and .027 Commetic gaskets to get .039 quench as well.
Stroker #1 went to Darrell Watters dyno on April 27, and made 507 hp and 546 tq. This one goes to the dyno May 4. It should be a fairly close comparison of the heads.
Stroker #1 is sold, and this one is for sale after the dyno for $10,500.
