Puuurdy santa seems to be a few months early

Here is a photo of the Yella Terra billet fuel rails:



And my new billet snout that arrived today with 67mm pulley. The 67mm is temporary until my 64mm is in stock.

I am almost positive the Catera is an Opel design.

RWD L67.... man that must be a fun a$$ car to drive. It looks to me that the Aussies have better parts for our cars, I vote we move the Bonneville Club down under

It is opel.

I know the toliets flush counter clockwise down there. Does that hold true for the superchargers too

They are good fun to drive... and yeah superchargers still spin the right way... mines just not as fast as it should be yet Had a lttle meet up (only a few cars) on the weekend. I was the only one that didn't wash my car... or have an Intercooler set up... dammit.

The other night I was cruising home from work at 11:30 and my car started to miss really badly. I couldn't hear any sign of anything mechanical going wrong. I organised a tow home and then the next night to a mates place. We tried all the obvious fixes and found nothing until we pulled the rocker covers off and checked the rockers, this is what we found:



The car was running FIT reworked 1.97:1 ratio rockers. There have now been a few cases of these rockers and bent pushrods. The ratio ona nother set has been measured and was apparently found to vary significantly.

We checked for obvious damage to the lifters, valves as best we could and compression tested and it seemed okay. We replaced the valve spring and re-installed standard GM 1.65:1 ratio rockers and new pushrods and the Calais feels like it is running quite well... hoping to have my new heads ready in the next few weeks so we can inspect further... argh.

Oh man, Ouch :?

good luck, hope you get things going again soon!

Wow, that was quite a high ratio for those rockers. I couldn't find in the post that you had replaced the bent pushrods. Are those doing well, then?

Opps, left that out. We replaced all the pushrods as it seemed with the variences that they were hitting on the casting flash a little. Enough to mark them all.

These 1.97'* have been a disappointment. Yella Terra are the way I am going for my next set.

I was suprised to see people running 1.97s down there. I know 1.95 is the largest raito we have in the states and it was said to be the max before hitting the casting flash.
