Thats because no idiot would make them.
Think about it, the front end would end up looking like a Lucas Oil Stabiliser Display. You'd be better off with a belt setup. but once again, what for and no-one would and too much work for a aussie engine.

Running a Jim Mock DEV 5 cam, I "stretched" the timing chain and broke the chain guides TWICE in the first 11000km of my rebuild!!!! Straight cut gears would have eliminated this issue and saved me $2000 in repairs [the second time a pieces of the chain went into the sump and destoryed the oil pump as well. The car stopped in the middle of Liverpool. $$$$ expensive trip getting it towed home + the time off work with no car + cancelling my holidays because I used up the money on the repairs !!!] And yes, I did realise that it would end up looking like a Lucas Oil display, but I wasn't concerned if it resloved my issues! Anyway, thats just my feedback. Hopefully others can learn from my experiences.

Anyway, thats just my feedback. Hopefully others can learn from my experiences. I had the same issues with my dev5 cam/head kit. I had the chain and gears and guides replaced the next day after we fitted the kit. Cam stretched the chain again, took the cam back out 4 weeks later and put in the stock xr cam, then put in a billet from surecam - no problems since. I wouldn't mind the straight cut gear setup, even if it is a bit noisy. Once I get the block rebuilt, a new chain will go in again. As quoted, I hope ppl learn from my experiance as well.

I had similar issues on a 4.1 engine I had rebuilt. The combination of Stage 4 cam and high volume oil pump did the damage - but on that car it was the dizzy drive gears that got munched. Apparently if you had big valve springs the cam would flex as well causing a poor fit to the oil pump gear.
Some very very carefull thought is required for big cams. |
