I like the idea of leaving it in drive but it seems to shift inconsistently and late. The reason I say this converter could be tighter is simply cause with the 3 sumptin low gear and 4.10's it really revs fast in 1st and goes thru the power band quick. I'm seat of the pants guessing but the power band seems to be around 4500-5500.

Got headers today too! Woohoo! Long story short, I'm whittling away at it and the car responded a ton to everything I've done. .5 under shouldnt be much trouble.
Install a Bullet Blueprint cam you will be fine....and very happy !!
Regarding 3.08 first gear on the 4L60.
On a heavy car like mine it just the ticket.

The factory cam power range, yup you are correct.. !!

Think tech would notice a metric 200? LOL
I was thinking a TH350 with a 4L60E tranny pan welded on the bottom! LOL! ;););)

Does the Bullet "blueprint" cam keep factory duration? Is that even published? If it has more duration your RPM range will be higher. On-track testing I have done with both my bone stock virgin LT1 Camaro & TA (not even headers that would effect it) showed quickest ETs (with proper tuning) shifting it at 6000 RPM. I'm not sure what you are seeing on an chassis dyno sheet that tells you the needed stall speed. You do realize, that with an automatic car running a loose converter, the numbers are skewed (out of sync with the torque numbers), right?

Yes it is published.

The engine was dynoed by Jeff Warren after he built it.
Btw where do you have a dyno?

What duration does the published spec show?

The chassis dyno in my shop for fifteen years. I now dyno my SS engine on engine dynos at either Patterson Racing Engines or Morton's Machine.

Bullet Cams calls Mike Baker to confirm Duration.
Mine was easy because the NHRA/IHRA uses the F-Body Cam specs for B and F Body LT1s.

Where is Patterson and Morton?

Patterson Racing Engines is in Augusta Kansas (Edge of Witchita, about three hours drive)
http://www.pattersonracing.com/

Stanley Morton has a smaller shop. He is in Broken Arrow, OK, about half an hour drive. Patterson's dyno set up has eight wide bands, Stanley's does not. Depends on what I need to do. Patterson builds Stock, SS and Comp engines mostly. Stanly builds Pro Mod and Top Sportsman stuff, also the best crank shaft guy I know.

Known both Stanley Morton and Allan Patterson for about forty years. They both also do machine work for me.
