My builder has used this cam before and achieved the results I am looking for so I changed it. Pure and simple, I trust his judgement and what he is comfortable working with. I am sure the Lunati is a fine cam.
I just ordered the Milodon 16250 high volume water pump from Jeg's and Ebay. If you order $100, they'll knock $25 off the price, so I threw a dip stick on there and got everything for $78.
The offer is good through the end of the week, so I think I may try and put a couple of more $100 purchases together. Anytime I can buy parts at 25% off, I'm gonna try and take advantage of it.
