So wouldn't a 308 be capped at 360?
05-07-2012, 02:50 PM #197
I think the cu in max is calculated on the largest option for that vehicle eg 350 Chev and is covered under the 'option' clause as below.
(i) To be acceptable in competition, each option shall comply with at least one of the following requirements:
(a) It shall be listed by the manufacturer as a “production option”.
If not there is the engine requirements section which states as below if I go Chev.
1.1 Engine requirements: The cylinder block/engine shall be standard, or a replacement cylinder block/engine is permitted subject to the following requirements:
(i) The replacement must be: a production cylinder block of the same configuration, with more than 2500
units sold for road use.
Here is the relevant section on capacity ...
1.2 Alternatively, a maximum of 17% increase over the original capacity of the automobile is permitted.
I put a call into CAMS a couple of days ago for clarification but I think the cu in max relates to 'the vehicle' and not the engine option currently fitted.
Thanks for bringing it up adp, it's easy to miss something as I had not noticed the block material and pre 82 engine requirement before.

Holley pump mount
I thought I would rubber mount the pump to see if I could reduce the noise. I went for rubber grommets from the chassis to the bracket then the same from the bracket to the pump mount. Result ... about 5% reduction in noise Those things are just noisy, that's it!

Targa Road / Rally interpretation
I heard back from CAMS today about the Tarmac Rally Technical Regulations – Classic
Engine - The 17% increase in capacity applies to 'the vehicle' and is calculated from the largest engine option for the model (350). They also confirmed that an LS engine is definitely OUT!
Tyre profile - post 71 cars can run 40 profile tyres but 71 cars can only go to 50 profile. CAMS advised that the 'run on rule' applies. That is that the HQ model runs from 71 - 74 and 72 models are deemed to be the same as 72 - 74 so can run 40 profile if they want. My backup argument was that replica vehicles are allowed and I would claim that my 71 LS model is a replica GTS 72 model LOL.
I will stick with 50 profile for now one because Improved Production requires it and two I can't get a 255+ 16" 40/45 profile Targa tyre. We are still limited to 16x8 rims

Mulling over engine options ... again
Gave the guys at Shafiroff a call the other night to see what they could do in 406 cu in being the CAMS Targa engine capacity limit. Spoke with Mike Ghiraldi who said that the best combo would be the ultra Street 434 434 UltraStreet Small Block High Performance Chevrolet Engine with the Saturday Night Special options and a 406 short. He said he hasn’t built this combo before but it will pull 550HP for sure but more likely 580HP.
The figures start adding up though, it would be about $14,000 landed in Aus ($15,400 with gst). Then over $5,000 for accessories, pullies, headers, carb, dizzy, mounts, flywheel, clutch, radiator, PS pump, circuit sump and other bits like oil cooler adaptor etc. I can’t see any change out of $20k but I may be able to get $4 - $5k for my current 396.
The LS engine is not allowed in Classic so the only other options are -3’s which will top out at about 510HP but should be ok with my girdle. I think the last costing was $5k.
Finally the COME 600 VN head conversion and a new 4 bolt mains block would come in at about $12k but could go to $15k depending on options. The good thing about this option is that I could do the top end next year keep the revs down and build up a 4 bolt block in 2014. 550HP to over 600HP wouldn’t be too difficult either. And the nice thing is that everything will bolt straight back on. The only concern is that late model blocks are well over $1k these days and getting more scarce by the week.
Still plenty of time but I know 550HP+ is going to allow me to play in the big end of town, 510HP may not …

T and Tyres
Had V2 of the Team T done for the wife today. We think it's a great improvement on V1 and will go with this design.
Picked up these bad boys from Chris at Tyrepower Frankston today ... Bring it on!

Good luck mate! Hope to see some more footage of this beast. Can't remember from earlier but do you have a Go-Pro camera?
Engine choice is a tough one. For people that have Chev's the Shafiroff is almost a no-brainer. That or other performance crate motors. But as you say the accessories, especially quality ones can make a big price difference if you're going conversion.
For what it's worth i doubt you'd have much trouble selling your current, killer combo.EFN 202 : knowledge is (horse)power!

Sort of off topic about engine choice. Just watch out from engines from the states. Too many stories of big dollar parts that are suppose to be in these engine being swapped over for cheaper options.
Better off buying the parts you want from the states and getting it assembled over here. Just my opinion.

Thanks guys, I wouldn't go anywhere other than Shafiroff. They may be slightly down on claimed HP but other than that I can't find a single negative comment on the internet. When I spoke to Mike Ghiraldi (apart from sounding like a mob boss from Queens) he was very straight up and had obviously built many engines.
When it comes to a new engine and should I decide on a Chev I will of course give first option to Aussie builders. However two recent builders said they couldn't get anywhere near the Shafaroff pricing.
On the other hand I prefer a Holden but I don't like the block availability issue, can't someone just cast up a Holden stroker 4 bolt block!!!
I would like a Go-Pro camera but all my spending is on going, stopping and cornering atm. I will take my domestic camera and hopefully get some in and out of car footage. The problem is that the engine shakes the cage quite a bit where the camera is mounted. The two cameras I tried both vibrated producing a blurred image.
Packing up now and will head off about 3PM.

The Go-Pro's really are all they're made out to be. They're simply the best option, though far from the only one.EFN 202 : knowledge is (horse)power!
