new swap firing order camshaft

J&S Racing · 09-16-2020, 02:50 PM

I recently had a 565 built by Schmidt, the father of the 7/4 swap. He put a cam with the LS firing order in it so I sat down with him and talked if it would benefit my stocker motor.

He basically said the 7/4 swap usually sees a small gain in HP but no big difference with the 4cyl swap. He said the advantage with the LS firing order is it drastically improves harmonics in the motor and is easier on the bearings.

Sitting in my rail the LS firing order definitely is a lot smother at idle.

More than likely I’ll have a cam ground with the LS firing order when it’s ready for its 1st rebuild.
