Stage 4 Camshaft Kit for Northstar V8

Pre-order. Your credit card will not be charged until these ship out! Expected ship date of September 15, 2023

Comes with 4 camshafts reground in-house at Northstar Performance on our CNC camshaft grinder. These cams will provide just a little bit of overlap for that "hot rod" sound and give you an (yet to be verified) approximate 375-400 flywheel horsepower out of a stock 4.6L Northstar. A little bit less for the 4.0L Aurora engine.

These cams will produce enough engine vacuum to run your power brakes, HVAC, etc. with no issue. A tuned PCM is included with this package. The car will drive nice as a Caddy should. But you will hear a different exhaust note, and you will feel the additional power.

No valve spring changes are needed to run these cams. No shims required. Direct install, which can be done in-the-car by someone qualified. Engine will benefit from stiffer valve springs to be released in 2023.

On 93-99 cars we HIGHLY recommend replacing all 32 valve lash adjusters (lifters) with new ones.

We will charge a core fee of $350 in addition to the price, which will be returned when your old camshafts and PCM are returned to us. To avoid this charge, you can send your PCM and cams to us in advance and we will regrind your cams, and tune your PCM.
