371 build W/Big Mouth heads
Seriously impressed with the octane tolerance of this particular engine. Had it back on the dyno yesterday and only had 87 octane. Dialed timing back a bit and did two pulls---525 hp 470 tq. What really got my attention is how it started, idled, and shut off after two back to back hard full temp runs. Next test is a splash of Avgas, then it comes apart. J.Rob
