Those would be max sizes I imagine.

Pre 76, 245 fronts and 275 rears for all.
5 litre Holden or Chev for the Toranas.

 

That would be cool if you could run somethink akin to a 1969 Z28 spec 302 SBC with a Tremec or Muncie and a 9" rear axle. Would make an LH a decent race car with brake and suspension mods.

I know Carey McMahon, his runs a 302sbc and I think a T10.

Go you good thing!!!

The TCM specs are pretty wild now, most are running similar things.
9 inch diff by race products, most use either tex racing 4 speed(full house spec t10) or jerrico(nascar spec).
There are weight limits, torana allowed to run lighter due to 5litre engine, less power.
Common wheel and tyre sizes.
And a rule some people won't like, torana is allowed to use the 5litre chev engine due to been able to get cheaper/reliable more power.

This ones running a Holden V8 I read.

I was watching the TCM practice on Fox yesterday, this one uses a 308 and as a result is allowed to be 100kg lighter. Limiter set to 8000rpm. The cars that run a 302 have to carry an extra 100kg as the Chevs produce more power. Commentators were saying though that there are smart 308 builders in Australia with bulk Commodore Cup and similar experience that can pull 580hp out of one under the rules but the challenge is keeping them together. Apparently they were popping the heads last year.

Chevs have more clamping pressure on the head gaskets, more head bolts so Holden's will struggle. Hden does have a good head ports tho.
Block strength is not as good with holden.
Torque power have addressed the issues with holden motors with there new little paw iron block and heads with extra bolts, they shld fill the void and push the holden motor forward, yay for us holden fans.
Always going to be hard on the big tracks to run down the fords bigger engines.
Fords are allowed rack and pinion steering and most cars use similar brake setups too.
Love these cars, better to watch than the v8's

Well 3 from 3. Bowe is the master.

[crabba67]

Is JB driving the SLR/5000 at Hidden Valley or was it just a one off drive.

[ozyozyozy]

Hope so😊, but might be a bit harder on a track that loves HP

[Shiney005]

[LXCHEV]

Awesome vid.... "I just want one" !!!

[hawk]

Awesome vid. Im curious as to what suspenion they run to get it sitting and handling so well.

[LXCHEV]

Yeah some specs of the whole build would be interesting.
