Last week I raced the Crossle at Buttonwillow Raceway and the afternoon temps were over 100 degrees. Well I found out what those cool looking air ducts behind the radiators are for on other cars I’ve seen, to divert the radiator exhaust air away from the pedal box. My feet were on fire, I actually thought my left shoe was melting! So my crew mate Art whipped up a cardboard air dam to get me through the weekend, and it worked great. Who needs swoopy looking carbon fiber anyways ;-)



Spent a little time in the garage today cleaning up the old 710 grill. Gave it a power wash, rubbed it down with a little fine sandpaper, then some acetone. Spray painted it with Krylon Fuzion plastic-adhering satin black, hand painted the perimeter with some metallic silver, cut and formed some 3/16″ stainless steel wire mesh for the headlight grills, and couldn’t resist installing a spare Datsun grill badge from the Wagon. Now it’s the best looking part of the car ;-)

The h165 axle on my Datsun 710 had 1/8″ toe-out and zero camber. It made the handling a bit twitchy and did not give ideal tire wear, so I took it to Paul Moore at The Moore Speed Co and had him fix it for me. After removal and measurement, he used the cut-and-weld method to alter the axle housing geometry to an ideal 1/16″ toe-in and 1/2 degree negative camber.

This a great old video from 1965, definitely worth the 15 minutes. It includes some race driving instruction around Willow Springs Raceway by Peter Brock, Ken Miles, and Dan Gurney.


This weekend I made my maiden visit to Portland Int’l Raceway for the 2014 HMSA Portland Historics, with Datsun being the featured marque. Over two dozen Datsun 240Zs, 510s, Roadsters, 710s, and even a GTR Skyline showed up to support the first ever major U.S. Historic event spotlighting the venerable Japanese manufacturer. Mr. John Morton of BRE fame was the event Grand Marshall, and he regaled us with great stories of how he got his start in racing during the HMSA-hosted Saturday night dinner and award ceremony.

The driver-friendly, 2.0 mile, 12 turn track has a dragstrip front straight, a curved back “straight”, and a fun complex of corners connecting the two ends. HMSA and the local SCCA track workers ran a nice, organized three-day event, featuring a practice, qualifying practice, two heat races, a warm-up, and Sunday flag race. Friday and Saturday saw record high temps testing car’s and driver’s cooling systems alike, while we raced in the rain on Sunday. Combined with a 12-hour tow each way, it made for a long, yet very enjoyable, weekend.

I battled some brake and axle seal issues with my recently purchased Datsun 710 race car on Friday and Saturday, but with the help of my pit crew and fellow Datsun racers, I had things in order for Sunday’s flag race. Thunderstorms and lightning filled the skies for race day, and while some groups raced in a drizzle, some raced in a deluge. Most racers stuck it out, but I was suprised by how many packed up and left in the rain. My B-Sedan/2.5 Trans-Am group got lucky with just light showers, but it still made for an exciting session on DOT cheater-slicks. I got to learn a new track, see some new cars, and make some new friends this weekend. We finished 6th in a group that started with 24 competitors, so I’ll call this Oregon adventure a complete success!

Well I still don’t have the motor back for my Crossle, alas my plan to race T-hill with SCCA this wknd was a bust. So I couldn’t think of a better way to spend the day than to visit my buddy Phil Mendelovitz who was racing at the Sonoma Historics! He brought his beautiful IMSA 240SX and his Ginetta G4 to run this weekend, and he even had extra crew passes for me and my wife (entry tickets are $35/each these days!). Great weather, great friends, great racing, just what weekends were made for. Historic Trans-Am, Can-Am, IMSA, just lots of cool cars and some really cool vintage transporters to boot.
