3 speed for captain jack

Jack McCarthy · 03-25-2009, 08:52 PM

well it wasnt the free ET i had planned on !

i have installed a turbo 350, 2.75 low gear with good insides, prepared by thomas arnett
it is a good piece using a powerglide input and my old converter

HOWEVER much to my amazement i was unable to ID anywhere on the track i made substantial gains..

the -1.15 was a good pass but not my best ever, however i offer these observations

1. i ran a glide for 28 years, and i knew what it wanted as far as gear, shift points etc.
.... the turbo was as fast as the powerglide on day one... room to improve
2. i believe i am over geared and will try the 5.86 instead of the 6.14 soonest
3. converter dropped flash from 4800-4900 to 4500-4600 i need looser converter

i believe there is ET there for me to obtain, however ill never beat that caddy

thanks to those whose interest has made this fun

Jack,

Thanks for the rundown!

I am curious as to the 60-foot times.

Were they better, the same, or worse?

Did you experience any wheelspin (that is NOT a trick question) with this new setup?

Thanks for the info!!!!

Hey Jack,

I would try that 5.86 gear before I changed the converter.
That should change the flash rpm in itself.
But I'm sure you knew that.
Good Luck!
