    8.75 Sure Grip spider gears break

    Thanks for the tips. I also believe that they break due to shock load when cornering over the curbs. Luckily I have now he whole winter to find a solution... :) Some video can be found for instance here:

    8.75 Sure Grip spider gears break

    I do double de-clutch always when shifting down, but I seems that driving over the kerbs is pretty hard for the diff. I've always had a clutch type diff in my race cars, with good results. Except with this one... Probably I'll try Truerack next if I can't find better gears for the Sure Grip...

    8.75 Sure Grip spider gears break

    While racing my vintage road racer Dart last weekend I broke the spider gears of the Sure Grip clutch type diff carrier again. This is already second unit within one year that breaks the similar way. The rear end is 8.75, and the ratios that I've had are 3.91 and 3.55. Car has a 273 engine and...

    Vintage road racer Dart '66

    So, my racing season of this year is over now. No DNFs in any race. The end result was not too bad, as I won the Finnish championship in my class of Competition Touring cars of 1966-1971, over 1600cc. :cheers: Some video from the last race at: https://youtu.be/2WhV4BIi6qo 273 and Kelsey...

    Vintage road racer Dart '66

    It's no bad at all when rememebering that all suspension mounting points are as standard, and there are only sway bars added, both front and rear. T-bars are of 1.12" dia and there are adjustable Koni shocks. It's still a bit too understeering in slow corners, but a bit more caster will...

    Vintage road racer Dart '66

    Last weekend at the Gellerasen circuit in Sweden. Some more stiffening to the suspension is still needed, but otherwise the car is handling pretty well.

    Vintage road racer Dart '66

    I had my first race of the season last weekend, and the car felt pretty good. During the winter it got completely new engine, rear sway bar and some weight reduction. There were two races during the weekend, and I was 2nd and 1st in my class. Next race event will be in Sweden after 2 weeks.

    Vintage road racer Dart '66

    Actually, I blew the bottom end of my race engine one week before this event due to oil starvation. That was because I used the original small sump with just some baffles added. So, I had just a couple days to make a new bottom end to it, and that was literally put together from the old parts...

    Vintage road racer Dart '66

    Some photos of my Dart in its first race event last weekend. The suspension was still too soft, but generally it wasn't too bad. Engine failure in the 2nd race though...

    Forged pistons for 273?

    Hello, I need a set of forged pistons for my vintage road racer Dart. It runs in Europe, and has FIA papaerwork, so 273 is the only allowed engine option. I just blew an engine that had Egge pistons (not beacause of the pistons though...), and now I'm making a new one. Does anyone know if...

    So, summer is approaching also here by the north pole... Here's the Dart in its current livery. The first races will be in June, but I'll try to get some testing done before that.

    Vintage road racer Dart '66

    Hi Dave, Thanks for the links. Yes, that's true that the FIA rules appear to be a bit more restrictive than what you are applying. For the engine basically the original homologation sheet is what's applied. All machining, pistons and camshaft are free, but adding any material to existing parts...

    Vintage road racer Dart '66

    Just a proof that my Dart is suitable for cruising as well :D : http://www.cruisingnight.fi/index.php?view=image&format=raw&type=orig&id=50026&option=com_joomgallery&Itemid=152 PS. That Le Mons Dart is very cool. Nice contrast against those computer age things.., :D

    Vintage road racer Dart '66

    Thanks for the comments and an interesting link for Benson's Dart. It appears that early A-bodies are not too common in road racing. Here in Finland we have two '65 Barracudas and one Valiant in the pre-66 class. One of the Barracudas is very fast, beating Facons and Mustangs frequently. Please...

    Vintage road racer Dart '66

    Greetings from snowy Finland! During last few years I've been building a road racer Dart for vintage road racing. Now it's getting ready, and next summer the real action will start. So far I've mainly raced a Triumph Spitfire, so it's interesting to see how this beast will behave. The car is...

    Trans-Am info for the 1966 Barracuda

    On this side the pond, FIA solved the problem of originality by introducing Historic Technical Passport (HTP). This means that basically there is no requirement of any originality, as long as the car is technically according to the period specs. So for example you can convert an ordinary Ford...

    Trans-Am info for the 1966 Barracuda

    HI Chris, I'm currently preparing a Dart '65 to '66 FIA group 2 specs, which is basically the same as the early Trans Am. It's got 273, A-833 and 8.25 with 3.91:1 ratio and LSD. The suspension springs are from FFI and shocks are Konis. Front brakes are the homologated KH discs and rears are...
