So, you guys know that I dont know much about this motor... it just came with the car. I do know that it's been massaged cuz I have some receipts from previous owner... but I have no cam info accept that the bill says it was replaced... stock, RV, street, race (doubt race).

Is there a way to tell lift and duration? I have a degree wheel, but have only used it to mark the balancer/pully with timing marks. Do I have to be really smart to use it otherwise.

Cheers... Brian
