Dave, how much were the Albins conversion parts alone? Did you do the conversion yourself? And how much did the entire 930 gearbox rebuild cost you? I've got a 930 box I'm considering converting as well. Any advice you'd offer after what you learned doing your gearbox? Jack

I'd call Lance at Superformance in Irvine. Where you are located may influence who he recommends: traffic in LA is so bad that the exotic car owners there I know have their cars transported to the dealership/mechanic for service. BTW, the SPF GT40 is a very straightforward and relatively...

I appreciate your sharing your knowledge, Trevor. After the parallel lower links conversion you mentioned, did the racecars you so modified subjectively behave any differently on track? And did you consider it a worthwhile modification? Jack

Thanks for your reply, Trevor. I asked because I own a sports racer someone built using uprights+suspension from a mid-1970's Formula Atlantic(Lola) which originally used the reversed lower a-arm rear suspension locating link. In my car, they replaced it with parallel lower links, leaving the...

I've noticed that McLaren, for example, went away from reversed lower a-arm in favor of parallel lower link rear suspension location(with single upper link and U/L trailing arms) on the M8F and again on the M20. And I can't recall (m)any modern rear racecar suspensions using the reversed lower...

It's Kim Petersen's Superformance Mk1. That's Alan Petersen in the video. Jack

Mine has a Buick V6. I've seen other Albas powered by ferrari, mazda, olds, even subaru 12 cyl. I'd like to adequately repair this nose so I can have the car painted and back on the racetrack while I look for another nose/mold. I've been involved with making a whole fiberglass mold in the...

I hope i'm not hijacking this thread, but I'd appreciate the fiberglass experts' help. I'm trying to restore the nose of an Alba AR5(80's GTP car). The nose was run at the Daytona 24 and has lots of star cracks, esp. over wheelwells(it is very thin fiberglass and there were no wheelwell tubs...

Kirby, My SPF GT40 has a potent 440" engine which delivers 630hp via 14" wide Avons. I have to pedal thru the first 3 gears because the tires will spin under full throttle. If I can barely use the 630hp I've got in my car, how on earth will your friend ever get to use all that power he's...

Hi Geoff, Great looking car! Olthoff Racing prepared my Mk1 as well. I drive mine everyday, and I've had zero problems even though my particular GT40 project was not routine. (Thank you Dennis and Paul). Jack

Just saw the Pinto spindles announcement on Wilwood's website. Never mind. Jack

This has been noted before, but you don't absolutely have to keep suspension arms out of the cockpit entirely. Have a look at the front lower control arm rear inner pivot on a friend's M12 Mclaren canam car. Its directly beneath the driver's right leg. Jack P.S. Where can I find out more...

I race a Shelby Can Am that came from the factory with a spool(equivalent to welded diff.). The spool certainly puts power down well (I know Porsche used spools on all its high powered sports racers throughout the 70s-80s; they may still). Not surprisingly, it tends to push the nose under...

All production SPF GT40s have a steel roof/spider. Thats one of the reasons I bought one. Jack

I agree with Cliff and Russ about run the transaxle as is and see. Back in the 1980's I was at Bob Norwood's Ferrari shop in Dallas, looking at one of his tube frame P4 replicas. It ran a 365 V12 thru an inverted G50 transaxle. Bob said he always installed the used Porsche transaxles just the...

The incar Daytona video was shot during the Sept. 2009 HSR race Group 7 practice. I was on track at the time. I followed the GT40R through the banking and into the infield (that's me driving my orange Shelby Can Am sportsracer beginning at 4:22). The GT40R looked and sounded magnificent! Jack

Believe it or not, for street use I have gotten by on local pump 93 octane in a 640+ HP 434" SBC running well over 12:1 CR. It has ported Dart AL heads and a BIG solid roller cam. During the build, combustion chamber squish was carefully optimized. It is carbureted, and has an MSD ignition with...

I own SPF Mk1 #2182. I'd buy roof vent and glass bulkhead window. All gaskets&seals in posts. Wheel bearing seals. Tow ring. And probably anything else interesting you come up with. Jack

Terry, I had the fellow in Dallas's phone number in my previous cellphone "contacts" directory. The phone got wet and died and I can't access the numbers on it. Let me look elsewhere to see if I can find it for you. (I have two 016s myself : they are so cheap I couldn't help myself). Jack

Terry, Since you have already done research, you probably know this already. In any case...I spoke with a fellow many months ago in Dallas who at the time was making adapters to mate LS engines to the 016 trans. So at least at one time someone was making these parts. BTW, I'm not trying to...
