Just wanted to get everyones opinion on what kind of power/boost I would get putting stage 3 heads on my stock shortblock with the stock cams. I decided to bite the bullet and get new heads after I kept having problems with my 4 thread heads. I got the heads from a SV on the forum. He told me that I shouldn't have trouble with the stage 3 heads as far as smog goes(in CA). Apparently its all in the tune. Ill be getting close to the max Ill want to run on the stock shortblock. So I don't really want to push it that much harder than I am already with the eaton(I don't want to thrash my new heads). plus, the cams have a bigger effect on smog than heads do. Anyway I understand I could get A LOT more power with cams alone rather than with just heads alone. Was just wondering what my boost would drop to and how much power I would gain. Also if it would be safe to throw on a different pulley to make up for the lost boost(even though Ill be putting down more power without it) I know that throwing heads like these on a n/a engine would totally kill the power unless u spun it to the sky. But it seems like it really wouldn't have that kind of affect on a FI engine. thanks for any input. I also got a sct 2600 just to be safe. I was hoping for maybe 445 hp at wheels. what do u guys think?
