Default Lt1 383 Dyno numbers
Just got the car tuned and I was pretty damn happy with the results.


Speed Inc 383ci custom cam ? RGR ported heads, kooks long tube headers, 58 mm trottle body, TH400 trans, 12 bolt rear.

The motor was heat soaked after the fifth pass and still pulled 467RWHP NA through a Th400.

Thanks Speed Inc.

Awesome numbers also!! Now lets see some track numbers...That thing should do 10s if its set up right, seeing as you've got around 60-70 rwhp over me....

Spent some extra money on light weight rotating assembly I'm sure this picked up some horsepower.
