for the price of ctr cams brand new, you could add a few hundred more on their and have a cam and valvetrain package that'll spank ctr cams. no matter what cam, will break if installed incorrectly.vtc8u said:shit i neve knew different countries measured octane differently i thought it was one of the things like macdonalds thats basically the same worldwide. i agree aftermarket all the way but if i can get the ctr parts at the right price ill be able to get it on the dyno and get the tunning done and il aslo maintain stock reliability cause iv hears a few horrors of cams breaking. with the ctr a parts and i/h/e i reckon 20-30hp maybe upward of 40hp with the tunning or am i way off
