40HP sounds good but from what I can ascertain it will cost close to $1,000.00 (Australia) and last for 40,000 ks before I need to do it again.
If I had a chev a new cam would cost $150.00 and last 100,000 miles. whilst we have two (exhaust) cams to grind I dont see it should cost 3 times as much and last half as long. A chev has 16 lobes on its cam. The 1UZ has 8 lobes on each cam so why should it cost more?
We have one of the best engines in the world and then put cams in them that wear out and fill the engine with metal filings. Where does the worn metal from a cam lobe go? Through the engine and hopefully the oil filter catches it.
I want good cams at areasonable price. I would pay $1,000.00 for a cams that would last 100,000 miles.
