heads (power?)

Morning guys,
  question is,,,what kind of power increase could i see with a set of AFR 165's.
might have a chance to get a good used set for a good price. mods are in my sig.
Thanks

I'm guessing about 30-40 hp.I have them on mine,big difference from the E-7's.they would like a little better cam though.

I think they would make alot more than that.

Take a stock HO and run it at the track in one of our cars. Now slap on AFR 165/trickflow/edelbrock heads, tfs-1 cam, cobra intake and than run it.

I think you could drop a whole second in the 1/4

If you have stock E7s at least 40 HP --- with a better cam, more likely 50-60...

I don't care if you guys do have a woody on for the E7s vs E6s, they both suck...

EDIT... LOL I see Bob is thinkin' like me...

My figures are through a full exhaust system, running open headers would net another 20Hp... But not many street guys can do so...

That's also if you don't mind revving to the moon...AFR's run real nice above 5000...throw some 4.30's and a convertor behind it...or just go 5-speed....if you plan on letting your AOD tell you when to shift(at 4700) then buying any set of heads would be a pretty big waste.

...and there's my :2c:

It's NOT necessary to rev the AFR 165s to the moon... I believe IF you bother to check they(and the other aftermarket street heads), give a significant increase in hp from approx 2200 RPMs up...

I have to agree with that,there not 225's where the rpm's would make alot more.Like I said,I run 165's there a good head,good power through the whole rpm range.You may want to change cams if your going that route.Also you may be heading into bigger injector range,other guys here may argue that though.

You might want to check the springs on them to,the older heads were not that good if they weren't updated.what cc are they and what rocker style do they take?

What magazine was it that put on a set of AFR185s on a Cobra engine and added 60hp?  They did move the cam to add more top end power.

If you have an HO, you're probably down 30hp from the Cobra because of the heads.  Go to the 165s and add probably 60-70hp, I'd say.  Maybe more.

Those heads have a 1.94 intake valve don't they? If so they'll smashey-smashey with the stock T-bird flat top pistons.
