I have decided just to make the 100 plus mile trip to a chassis dyno.
It has been hard t get runs at the track.I mph at 117-118 11.6 secs
To recap, my heap weighs 4000 lbs with me in it.
I have a 520 ci rb stroker, 670 net lift cam 260@50
TF heads flowing 370 @ 700, 337 intake, 2 " primary headers.
Calculators say I am making about 550 hp. Not sure if they factor in shift changes for a manual trans.
After checking the AFR, with the exhaust intact, I am at 11.6-8 range at WOT. I do run it with exhaust off though, not sure how much leaner that would make it.
After getting a good dial back timing light, I am running 42 degrees total timing all in about 3000 rpms.
Any educated guesses on how much more power I'll make by leaning it up to high 13s and limiting the advance to 36-38?
