I Hate Dragsters250 Baby Blowers and torque Converters
Nitrous1...I have nearly the same setup as you with the exception it hasn't been ran yet. What did your combo run prior to the blower?

your air bleed setup is as follows
from the center (vent tube) they go outwards in this order ..
high speed
idle
intermediate

Ran 5.30s in a 2500 pound car with a alky carb. Probably run 4.90s in a dragster. It has a terminator on it now

ThurstonThanks Paul, I did finally get hold of APD and which gave me the same information. And you are correct about the carb Oakley uses.

Triple NickelNitrous1,
Is that aluminum block or iron? How heavy is the car?

Iron 9.8" New combo haven't weighted it. I'm guessing 2100ish. shipping weight was 110 pounds. Was 2000 pounds even with a 10.2" 598"

Triple NickelNitrous 1,
Yeah 9.8 vs. 10.2 in iron I believe to be around 40 lbs give or take 5 lbs or so. That puts you right where i'm at. We are exactly the same (2000 lbs with driver) pre-blower but i kept the tall deck and added the 250 blower.
I'm considering another blower build with conventional heads 380. Did you build the 555/565 specific for your small blower build? I was considering going 598 to keep it the same as the one in my son's car, but if a 0.250" stroke deal 540/555/565 gets it done, I may go back to the low deck world.

Literally bolted it on. Didnt touch the motor. I still have the 598 ran 4.70s. probably 75HP better then the 565.
The 598 may get the blower in the future. Just wasnt sure about the Manley Crank and Compstar I beam rods at this power level. the 565 has Callies and BME stuff
