History

Update: The remaining cars from the Bill Wonder collection will be auctioned off at Gooding & Co.’s Pebble Beach Auction in August, 2022. This McLaren can be purchased outside of the auction, with plenty of time for appropriate due-dilligence and without the pressure of the auction. Please contact us. The owner has retired from racing and McLaren will be sold.

Chassis number 70-03. Ordered directly from the McLaren factory by Canadian racers Roger and Maurice McCaig.  Raced in Can Am in 1970. RacingSportsCars – Roger McCaig, with multiple top 5 finishes.

Purchased from the McCaig brothers by William Wonder to race during the 1971 season. Wonder raced the McLaren in the Can Am from 1971 through 1973.

Thereafter the McLaren was purchased by Mac Archer, and was campaigned in historic races. Maurice McCaig later repurchased the McLaren from Archer, and it remains with Maurice today. There is a full chain of ownership for the McLaren since new.

Description

The McLaren has just been through a tub-up refresh. Work included disassembly, inspection, refurbishment and reassembly of the chassis by a pro shop. Work included, but was not limited to, the following:

Front uprights disassembled, crack checked, and rebuilt. Brake and clutch master cylinders rebuilt. New clutch slave cylinder installed. New Odyssey PC950 battery installed. New U-joints installed in rear axles. New fuel cell foam installed. All visible steel parts on the chassis were zinc chromated, including the original bulkheads. A new fire system was installed. The entire tub was also polished.

The Hewland gearbox was fully disassembled and stripped for rechromating. The gearbox was then inspected, discovered to be in very good condition, and reassembled.

The big block injected aluminum Chevy engine was rebuilt by Huffaker Motorsports. New bits included a  Crower crankshaft, Carillo rods, a Cloyes timing chain, Manley valves, ARP rocker studs, Isky valve springs and retainers, etc.  Huffaker dyno sheets show 688 h.p. at 6000 rpm. The dyno sheets, and other receipts totalling over $25,000 are available upon request.

This is a highly original car. It still has its original aluminum foil chassis tag on it showing chassis #03. Another chassis plate comes with the car and is believed to be the original with glue remnants still on the back of it.

The McLaren is back in the hands of its original owner, Maurice McCaig. The car has been authenticated by him, and is also authenticated through the car’s ownership history and records. The McLaren also comes with its original Can Am and SCCA log books.

If you are looking for a no-stories, original McLaren Cam Am car in excellent condition, this one deserves serious consideration. How many such cars exist anymore?
