Quick follow-up on this one....
Customer finally got the engine in his '69 Mustang. Been fighting suspension and torque converter gremlins, along with a faulty vacuum gauge, but we're making process.
This first run was an 11 second run, with traction loss up to the 60' mark, but the trap speed was 137 mph.
Turn the volume way up, turn the YouTube resolution up to 1080 and let her rip...

He followed that up with a 9.86 and a 9.82 @ 138, but he was short shifting at 6500 rpm. After looking closely at data logger, we saw that the driveshaft rpm was still way off of the engine rpm, so we expect we are still blowing through the converter. In addition to all of that, the custom aftermarket Powerglide has a 1.58 1st gear, so it's like taking off in 3rd gear....
This engine made 777 hp here with a conservative camshaft. I have another camshaft here that will probably net us around 820 hp. We were sandbagging just so that he could get used to the engine......last one was a 408C making 575hp and he had to totally re-vamp the car/driveline/suspension.
I expect 9.50's at 140+ mph here soon. On engine freshen-up this fall, we plan to swap a few parts so that we can spray next year.
