Here's a stump puller combo...
It's in a stroked W72 for my 1978 Y88 Trans Am The engine is built to look completely stock with correct XX block, 6X heads, stock cast iron 10003395 intake, and correct 17056263 quadrajet. Len Williams provided the stroked short block XX, and Dave at SD Performance provided his full package 6X heads, the CNC'd and polished intake, and his Stump Puller cam. Cliff provided his top line rebuild kit spec'd for the engine and it proved dead nuts on. The lifters are PRW 1.52 rollers.
Yesterday morning it landed at Kauffman Racing to get broken in and dyno'd. Everything went great with no meaningful drama other than a small water pump leak and stuck thermostat. It came to life after the second bump and I am really pleased with the numbers and lack of issues that were encountered. They recorded peak HP of 474 at 5100 rpm on the 6th pull, and peak torque of 549 at 3600 rpm on the 5th pull.
