400 428 455 Pontiac Crate Engines

400 428 455ci Crate Engines

Bill Cannon, owner of AwesomeEngines®, started drag racing with his 1965 GTO 428ci 4 speed car in 1975. Now that we are a fully CNC controlled machine shop with our Centroid 2013 B4250 block machining center, we are the one that can put a Pontiac together better than most and as good as anyone. 40 years of Pontiac work makes us one of the best places to purchase your quality re-manufactured or brand new Pontiac street or racing engine.

The block starts with being boiled for 4 to 8 hours to remove all debris from the entire block. Next, hot washed 30 minutes then carefully checked for defects. After 100% inspection of the block it is loaded in our CNC machining center then fully CNC probed in every area of the block to 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″ to correct angles and placement if needed. The block is lastly rotated 180° and radial clearance if you wanted a stroker upgrade up to 4.5″ stroke. The block is removed then honed to specifications of .0002 near dead on then hot washed again.

Meanwhile on the other side of the shop, the crank shaft is treated to a full inspection and only ground to an  under size if not perfect in standard. We  recondition all rods to perfect specifications. Then, internally balance the complete assembly. The Pontiac steel heads are completely reconditioned with upgraded exhaust seats if needed as well as all new valve guides. 3° angle valve job for the new intake and exhaust valves, Heads are resurface then new valve springs, retainers, locks, PC seals, set up for camshaft choice.

We then purchase a complete master rebuild kit with all appropriate sizes for pistons, wrist pins, rings, bearings, seals, gaskets, oil pump, timing set, cam, lifters, push rods, rocker arms, as well as oil pump, pick up tube and small parts kit if available for year make and model all OEM standard.

New cam bearings, brass freeze plugs are installed then the complete assembly of the engine. The now completely professionally assembled engine has its oil pump primed, new spark plugs then fully dyno broke in and tested for 4 hours to make sure all components are broken in correctly and all engines vitals are perfect. Who can control all aspects of the engine in house and get a perfect broken in engine with a dyno sheet with every aspect of the engines performance as well as all temps, oil pressure and power up to 5000 rpm? Why would we let you do it with a chance of missing something and damaging the engine then of course, its always the engine builders fault. We never leave this to the purchaser to have to do because this is just a way of getting out of a problem when you have one by saying the break in procedure was done incorrectly. Ever heard of “its your fault the engine failed, its not covered”?  We do not do that.
