this won`t give any power, but it grabs a good second gear, with rubber. b&m kits are easy to install and it will raise the pressure shift point also. help from a buddy, you`ll need more hands.

remember a stock 400 has a higher 1 gear than a 350 turbo. cheapest power gain is more gear in the tail.

I have a posi gear is 373 I think, put it in last summer. My 350 is bored over 30, holly carb, headers, 202 camel hump heads, oversized cam, roller rockers 1.5, it just doesn't seem to have the power it should, it is in a 85gmc pickup shortbed.

What is your timing set at.
what cfm is the carb onit now.
What is the compression ratio of the engine.
