FE's have chambers north of 77cc's and AFR does not make FE heads. I think you're talking about Windsor heads. Please clarify what we're talking about.

HELLO!
Are you building a 427 Windsor??? You're calling it an FE, posted it the FE Forum, and they're giving to FE information.
Everybody sleeping through this or am I wrong?

Sorry about that, I wasn't thinking straight. Mindset was i'm building a motor that will end up being a 427ci motor, a 427's an FE motor, but a still a windsor based block. Sorry guys

OK, now we're getting somewhere.
Tip: In future post in 'Small Block Talk' forum. You'll get more help 'cause those guys almost never look at the FE forum.

You don't say if track car or street only-just that you want max HP without big compression. At 11:1 on 93, you can easily and comfortably get 550 to 575. I would use 255's or something in the 235cc range, with 2.08's and 1.60's, an hydraulic roller around 245 deg and .660" lift and a 900+ cfm Holley or even a 1050 Dominator-if not in a Cobra.

Brent Lykins on here specializes in good Windsor builds.

The more info you give the more effective advice you'll get.
