400 428 455 Pontiac Crate Engines

400 428 455ci Crate Engines


Having our fully CNC block machining center, we are as good as any and better than most. With over 40 years of experience building Pontiac engines, it helps us be the  best places to purchase your re-manufactured or brand new Pontiac street or race engine.


The block starts with a slow hot acid bath to remove all debris from the block. The block then gets hot washed then carefully checked for defects. After 100% inspection of the block it is loaded in our CNC machining center. It gets fully CNC probed in all the areas of the block so it can be finished machined to blue print perfect specifications. CNC race prepped dead on bore centers and 45° bank angles bored from .020 to .060 over. The block never leaves the machine and is then resurfaced to 45° perfect bank angles. Lifter bores are machined if needed to .875 or .904″ to correct angles and placement if needed. The block is lastly rotated 180° and radial clearance if you want a stroker up to a 4¾” stroke. The block is removed then honed to specifications of .0002 dead on then hot washed again.


Crank shaft is treated to a full inspection. Then, only ground to an under size if not perfect in standard. We  recondition all rods to perfect specifications with brand new ARP bolts. Then internally balance the complete assembly.

Pontiac steel heads are reconditioned completely including a real 3 angle valve job on the intake and exhaust valves to find home. Heads are resurfaced, hot washed again, then new valve springs, locks, seals all set up for camshaft of choice and assembled correctly.


We use a complete master rebuild kit with all appropriate sizes for pistons, pins, rings, bearings, seals, gaskets, oil pump, timing set, cam, lifters, oil pump, pick up tube, freeze plug kit and small parts kit if available for year, make, model all OEM standard.


After completely assembled, the engine gets the oil pump primed, new spark plugs then to the dyno. We run the engine for break in and insure all components are functioning and all engines vitals are perfect. We control all areas of the engine on the dyno with every aspect of the engines performance as well as oil pressure, engine temperature and power recorded up to 5000 rpm? We never leave the crucial break in period to anyone but us that know how to do it best.
