Description

For sale:
A ready to install,1967 production year, 427 cubic inch, 400 horsepower, Tri Power, numbers matching engine for a Corvette with a 4 speed transmission. This is a mid production year engine that is correct for a 1967 Corvette produced starting in early February and on for several months. Note that as usual, the block casting date is not crystal clear.  We are convinced that the day of the month is 13 but it could be 18.  Really doesn't make any difference.  There is a standard, one year warranty.
If you are interested, please read the details below.  If you have further questions, please ask.  If this engine is dated too early or too late for your car, we may be able to build one to match your car.  Please check out the other engines we currently have listed. Finally, if you think this is a lot of money to spend on a correct engine, remember that it will not only increase the value of your car by probably at least twice this amount, you will have a new engine.  Its a win win.
Stamping:
The engine assembly stamping on this engine was done by myself and is a correct copy of the stamping done by GM with simulated broach marks.  See photo.  I have been doing these stampings (mostly Corvettes) for over 40 years and my previous stampings have passed literally hundreds of NCRS judging inspections, Bloomington Gold judging, and the scrutiny of major auctions over all these past years.  As far as I know, engine assembly stamping is totally legal in all 50 states but not to be confused with VIN stamping.  Even with my record, can I absolutely guarantee that this stamping will pass any and all judging, NO, because judging is subjective.

If it needs to be shipped, I get a major discount with UPS Freight (a division of UPS) and will certainly pass that pricing along to you if you so choose. Or I will deliver the engine to any of the major carriers located in Omaha free of charge. If the engine is shipped, I will build a completely enclosed box with a pallet type bottom for the minimal price of 0. Trust me, the box is sturdy and will get the engine to you safe and sound. Over the past year, the charge for shipping a complete engine to a business (or a UPS terminal) on the east or west coast has been averaging 0 using my discounts. Cost varies depending on destination and other variables such as going to a business or a residence.  Buyer is responsible for all shipping charges.

My partner and I are a two man company that provides the correct engines for early Chevrolet restorations. For 30 years we did almost exclusively Corvette engines but have now branched out to the Chevrolet collector and muscle cars of the ‘60s and early ‘70s because of the demand. We are in our early 70s and are supposed to be winding down so we only do 50 or so engines a year. I am a retired mechanical engineer and my partner is a retired dealership service manager. We have both raced Corvettes for 40 plus years and have held several national drag records. We have 200+ blocks stored away in a number of old buildings – enough to keep us busy until we “really” retire. The company name is “HiPerformance Restoration Inc, we incorporated in 1980, we are located in a small Nebraska town near Omaha, and we have shipped engines to most of the Continental United States, Europe, Canada, and Australia.  Twenty plus years on ebay without a single negative feedback - not easy in the engine business.
