Default Dynod the 391 today

Was at a dyno day today, and got a couple of runs in. No wideband, so I still need to do another run somewhere with that so we can finalize the tune. As is, it's running very rich with conservative timing, but numbers were 494HP & 442TQ. Pete thinks there's probably another 20HP in it with proper tuning.

Here's a video of the pull:

FYI in the LPE 390 the car pulled the same numbers at 12.8 or 13.0 to 1 AF ratio but give it what it wants and see


500 here you come! more specs on the engine! Very good numbers indeed.
