Product Details

About this part

You will receive an email after placing this order to confirm freight and final shipping cost.

Engine core is not included. You will need to supply a healthy core or purchase a core from us.

Stage 3 keeps the factory 3.0L stroke and shifts the focus to the head. We do 5-axis CNC porting in-house along with a full valve job, smoother ports, less turbulence, better seal, more air moving through the head at the same displacement. Rods, pistons, bearings, and cams carry over from Stage 2, and oversized ARP studs with the in-house machining that fits them carry through as well.

It is built to safely support tuning up to 1,300 WHP, not a promise that your engine makes 1,300 WHP out of the box. Send us your engine or buy a core from us and we build the whole thing start to finish. Either way it comes back ready to run once it's through break-in.
