I am sorry guys, I thought I finished this..
I was looking thru the BPG nats results, and saw Mike Erickson.. that is the guy who owns this first one. That got me to come back to the thread, where I noticed I needed to finish it up.
I see he is running 9.20's in the heat... And I am sure it has well over a hundred passes on it by now. He races it a lot, and is not bashful with the fuel.. he will run 10-15 passes a weekend. It's been in two different cars now. (edit.. accordng to Mike, it has just shy of 400 passes on it )
It was built specifically with this type of usage in mind, we selected the TA block for durability, mainly, not because we were out to set the world on fire.. that is also evident in the moderate cam specs, and E-85 fuel usage. I was very happy with the power this combo put out, it was more than I expected. Our target was a reliable 700 HP motor that would go 3-5 seasons between freshening. 300+ runs.
Anyway, here is the dyno stuff.
First, we tested with a 1250 and Race fuel. If you recall, this combo is actually going to be run on E-85, but we wanted a race gasoline baseline.
Nice easy pwr..
And then on E-85, after several pulls fooling around with the carb.
Note the good idle quality at 800 rpm. The stumble going into the pull is common on these carbs, and is a phenomena that you only see on the dyno, with a slow throttle opening. They never get the transition circuits right on these aftermarket carbs.
I might venture to say the first "low maintenance" 750+ HP Buick bracket motor. There is nothing wild about this thing, just big cubes a mild solid race roller with decent heads, on a good foundation.
A wise investment in your drag racing program.
