This thread sure died quick.

 

ha you got that right.

 

Id like to see what LE's stock castings are doing. Im working on a CNC program for stockers and this is what i got. Still working on the intake but the exhaust is what it is.

Int (.200) 148 (.300) 202 (.400) 244 (.500) 265 (.600) 271
Exh (.200) 140 (.300) 173 (.400) 205 (.500) 218 (.600) 224

The exhaust side was flowed with a pipe. And this is LT1 Aluminum heads.
