1984 Chev K30 5.9 6bta Cummins
Purchased this K30- new in the spring of 1984 to add another truck for pulling my
24K gooseneck hauling my backhoe or dozer.
The 77K30 performed this very well at 28K CGW
However this truck not so much.
I found out early that the GM 6.2 Diesel was fine for a Blazer, marginal for a
3/4 Ton, but pitiful in a One Ton.
Truck was a K30
400 Turbo Hydramatic
No-Spin Rear, Trac-Loc Front
In 1988 after considering a New Dodge W350 CTD
I opted for purchasing a New Cummins 6BTA 5.9 200HP engine
Through Cummins and installed it along with a ratio change to
3.73, and Upgraded the TH400 to a Built TH475
This Chevrolet became a whole different animal, and very satisfied
With it's performance.
