1.70 or numerically lower first gear. 3 speed for 1/4 mile.
1.30-1.38 first with 5.00 rear for 2 speed 1/8th mile.
We run the same engine with a brt lenco 3 spd. Its very tough but heavier than the lencodrive.

 

how much heavier is the bruno?

My BRT with 3 spd CS-1 weighs 167 lbs with aluminum bell,dry no converter.

 

bruno/lenco

what you think about powerglide and a 486 rear tail gear and 180 first gear in the same car listed above. you think thats to much fist gear. oh yea 34.5 tire

 

Lenco clames 135 lbs so about 30 lbs hmmmmm

 

brt

Snyder told me 137lbs for a 2 speed lencodrive...doesn't add up...i'm thinking they meant a 3 speed.

 

Plenty of gear but it will work. Just have to soften it up/kill timing on the hit. The latest strategy is throw gear ratio at it until you work the conv. harder. With that ratio and a wedge you will have to dump nearly half your timing to keep the shakes away. We ran 100lbs heavier than you but going from a 1.80 to 1.72 low with a 4.56 calmed it a lot.
Call me and i'll help if I can.
BTW we are looking for a 486 and have a 456 on hand.
