Thread: cam rocker powerband

There is one problem i had but cant remember if it was before or after the rocker install at 1000 rpm plus or minus 300 rpm i get a slight vibration from the engine in park you guys think i should start off with a compression test and cyl. leak down test

1.9 rollers are good for a 3 to 6 whp gain over stock if you are lucky. They will slightly increase duration and overlap so you may lose torque but it should be impossible to notice.

With 125000 miles on the engine should i be worried about the timing chain and tensioner with yt 1.9 and comp 105 springs. While i am doing the lifters And intercooler i figured i would do the chain Tensioner and oil pump what do you think
