A good friend of mine wanted to put a set of big block Victor heads on my flow bench that he ported so we checked them out today. As always when I switch adaptors on my bench I take five minutes to check calibration. With a 300cfm calibration plate on it read 300-301cfm so that checked out good as usual. Now a little about his car. It’s a beautiful unmolested 1972 duster that weights a hair over 3500 pounds. It’s a low deck 4.500 bore stroker with a 727 transmission (transbrake) Dana rear, pretty sure it’s been 1.28 sixty foots, .690 lift roller cam, Indy intake he ported, and it’s gone 9.58 at Keystone Raceway Park. Like I said this car is beautiful and hopefully he sends me a picture or to to post up. I told him he had free bench time and we would have an enjoyable day so we spent 4 plus hours together checking flow with his intake on and check intake and exhaust airspeed.
