Here’s some pics of an LS engine we did a cam swap to. The engine had a BTR (Brian Tooley Racing) camshaft installed in it which was a little too aggressive for the application. Since this vehicle is a Chevy Tahoe which is an everyday grocery getter we elected to install a much less aggressive camshaft from Comp Cams. The engine immediately idled much smoother & gained a bit more pep down low in the RPM range after we test drove it after swapping the cam.
