I'm thinking about some used AFR 165's with 1.6 crane energizer rockers for sale.

My car has:
Powerdyne blower - 6.5psi
Edelbrock Performer intake
75mmTB
70mm MAF
30lb injectors
never had the valve covers off. 65k mi.
It made 318whp/340wtq on a MD a few weeks ago and I'm wondering:

a) what kind of power can I expect to gain?
b) what % can I expect my fuel economy to drop (hwy & city)?
c) will my stock cam be too streetable to take much advantage of these heads?

Thanks for the input.

there is a guy over in the 94-95 section with 165's, stock cam, and a blower making around 415 rwhp.

id expect near 400rwhp. doubt youll hit 400 but it will be close. maybe if you added a couple psi of boost youd hit it. the get the heads and buy some 1.7 rockers instead for a little more lift.
i run afr 165's with the stock cam. dynoed 403rwhp and plan to see near 500rwhp when i get on the dyno in 2-3 weeks. with the stock cam the car is very streetable and im still emissions legal in california

Good stuff. I'm not expecting 400hp on a MD, on a dynojet maybe.
Good idea about the 1.7's.

They're the 58cc ones so I'm wondring if my cr will go up a ton over stock.

Compression wont go up that much, probably not even half a point. And the alum. heads will dissiapte the heat faster, so it wont make much of a difference..
