400 with Speedmaster Dyno Results
Just thought I would post the results of a recent dyno session. It is a .040 400 with Icon flattops, Eagle rods and HR cam. The Heads and cam were bought from Pontiac Speed Shop. All pulls were made with a 770 Street Avenger
carb. The sheet posted was with a TII and a 1/2" Super Sucker spacer. We tried an RPM and it made as much HP and a little more torque but it took a 1" spacer and since I am putting this in a 79 TA that won't work very well if. Peak numbers were 434 HP and 458 TQ. I was told this was a conservative Stuska Dyno.
