I nixed that idea and just gonna put the blower back on my street car. I don’t have the crew or car to use the blower in a race application so cruise nights and burnout contest it is on a stock block 462...

So Johnny,
Is this a different version of the 535 I saw you race at Great Bend, a couple of years ago? Or another? I hope you (and I, long story on my end), can make it to Great Bend, this fall!!! Thanks, Jeff

great video, i have no idea the amount of effort it really takes to do those types of things but it looks like you have the editing skill and the right equipment. well done.
what are cam specs if you dont mind and how much did you gain from the last time you dynoed it? any details on the 1250 carb are you using?

So the Q-16 fuel was worth + 43 HP at 5500 rpm, is that right?

We never dynoed it with anything but Q16. We put 112 in it to warm it up and that was 2 gallons worth. Our pulls were 5500, 6000, 6500, & 7000 twice.

Gain from last dyno is about 27 hp. The cam is a Comp Cam, 50 mm, 4/7 swap, 281/292 @ .050 on a 112 with .485/.471 lobe lift. The 1250 I bought off a guy with a 1270 HP naturally aspirated 555 BBC. It’s jetted 100 square...

That had to be a higher rpm sweep than normal? 7-900?
