I got a piece of ass and a sweater- and they were both too big

The whereabouts of that car were indeed known for a long time, I can remember my Cobra buds talking about it in the late 70's, and there had even been semi-serious discussions about "engineering a rip-off" as the owner wouldn't budge. I still have all my old Sports Car Graphics and such from the period with the race coverages, pretty sure that car wore #10 at the Daytona Continental, but the number went to the GT40 for Sebring. It was also used in Red Line 7000, where it was posed in a ditch, ran at Bonneville, and was listed in the magazine's For Sale section for quite a while for $10K. seems like it was in a shunt with front end damage, and maybe an engine fire. Lots of drama around that one. I would bet it's the #10 in the picture, as the Coupe has a rounded roofline with the GT40 pretty flat, and the "GT" class emblems are a giveaway, Coupes ran GT, GT40 was in Prototype at that time

The 501 was the largest six, and a torquer. 534 and 549 were more modern V8s and needed a little more rpm to make their best power- but still governed at around 3400

I took a fish head out to see a movie- didn't have to pay to get it in! 

Unfortunately, many folks feel they "need" big hp numbers in Cobras- many also get hurt or worse in them. I used to run with one of my best buddies and his cohorts in the mid-70's and the 80, whe were really big into Cobras, when you could still buy one reasonable and run the piss out of them. The factory drivers never really cared for the 427 cars that much, because they were a PITA and twitchy to drive fast. That and the fact that a late USRRC/FIA spec 289 race car with the big fenders, wheels and brakes and a good Weber'd engine in the hads of a good pilot would give a 427 car fits on a tight course. I have ridden in originals back in the day, with (one in particular crazy mofo) drivers who new them well and could shoe them pretty good, the CMF used to think it was fun to break the tires loose going into 4th at around 110 with one hand on the wheel, and yell hey don't worry about it, I got it all under control. The fastest on in the Bay Area group back then was an upgraded street version with a basic 454 TRW stroker setup, nice MR heads and a Crane, pretty rapid and simply known as "the red car". It ended up looking evil as the boys (not the owner) got loose with it in Vallejo one night and whacked one of the rear fenders into a parked car- so they had an old aluminum smith widen the rear fenders 6" and stuck 15" wide rims under the back- on bad red mofo. We were all set up to have him bring it up to Napa when Niel Britt from ChebbieCraft came to town for a Cars of the Napa Valley thing around 1980, but he showed up having traded it back for his old late-spec USRRC/FIA car. So, CMF was chosen to take Chebbie Niel for a ride- chugged out the driveway grinning and winking at us. Around the corner and waaaAAAHH..waAAHHHH..WAA-wu-wu-WAAHHHHHHH... Came back a few minutes later with a bigger grin, and old Niel having a death grip on the cowl and door and looking very pale- got JUST a little sideways in 3rd, and scared the dogshit out of 'ol Niel. Then we rolled out race GT40 #P1009 (it's race history with Peter Sutcliffe is well documented) and Niel didn't want any more rides

The testing in the Lorenzen car was / is no secret, pretty well known and documented, as was the 64 Galaxie going from Passino to Gordo Cooper for $1. The SOHC got effectively legislated out by huge weight breaks against it which would have made it look like the Hammy cars "beat" them- just like NHRA did with Jenkins' small block Vega, just gave it a huge weight break compared to just about everything else, Hammys, B9s and SOHCs, and in particular the Cleveland, to make the Chebbie fans happy as it appeared the Vega "beat" the others, when actually, as with 'ol Hillary, the fix was in

That's always been the worst part of an Algon setup, the throttle bores aren't very big- runs real well on a nice hot rod engine, but won't feed a next-level bullet. My magnesium Kinsler 351C sprint car injectors should be a different story- I figure if they could feed a 9500 rpm 410 Cleveland, they should do OK on a 7500 rpm 505 FE   

Yep, the Isky's are strong as hell- I bought a set in '77, they've been run on up to .660 lift, and are on my Galaxie today and are still like new
