71 Dart get 408/ Trick Flow Heads....
Who's lifter is that one?
Comp 2901-16
Was run for a full summer of street/strip use.
It was run on a fast rate .904 cam in an unbushed(uncorrected) block.
It was discovered afterward that the heads did not have the step removed for the inner spring(so, preloaded an extra .100”), and the motor was being run without high zinc oil or any zinc additive.
The replacement cam was done using a little slower lobes, the spring situation was rectified, and the proper oil is now being used.
Two seasons on it so far(along with some new “bests”) with no issues.
