If you're planning on an electric fan and underdrive pulleys, then a 130amp alternator is a must!

1.7s with the stock ho cam will work without problem in your application.


actually, would 1.7's work with a HO cam and SO pistons still, if i have E7's that are milled .008 off? i dont think the .008 would make a difference, but i would really like an opinion or two before i bend a couple valves and feel like an idiot.

It's not .008" lift it's .0.33".
Stock ho cam lift with 1.6s is .444",with 1.7s it goes to .477" lift.

im asking if milling the heads .008 off would bring the valves too close to the pistons with 1.7's. cus now theres .008 of steel missing bringing the whole head down that much. like i said, i doubt that little bit would make a difference, but i'd rather ask if someone knew.

The only real way to know is install the head with some modeling clay on the piston(maybe .200 thick)... rotate it twice, then remove the head and measure the thickness of the clay... I believe it's something .100 minium on exaust and a little less is OK on the intake... You can do it with out a gasket, just add .041 for the compressed thickness(or what ever the gasketmaker says the thickness will be)...

The only problem is that I need my car 5+ days a week, hence the reason I'm focusing on smaller upgrades for now.  But, I was thinking about the rockers, and what you all are saying is right.  The valves are opening at the same time, but now they're just opening more.  The piston should be pretty far away at the time that extra opening comes into play.

For what it's worth, I had 3.73's in my '88 Bird and it made all the difference in the world...fuel mileage was still very good and my cruise RPM on the freeway wasn't excessive at all....4.10's may have got me into the 13's if there was no headwind that night...oh well, we'll never know now....I had VERY little done to that car and it went exceptionally fast...with a 300k mile block.

There are always ways around emissions...I live in NJ and it's the worst(behind california) for inspections...I've only had one emissions legal car in all my time driving.

Either way you go, good luck with it!

P.S.-I know people say not to run more than 14* base, but I got my best runs at the track from 16* on Sunoco 94(which they no longer seem to sell in south Jersey).

For the cost of 1.7 you would be better off puttin better headers on,The 17's wont gain you much.

I still say get the 1.7s... I addition to more lift they free HP due to less friction... A set of better headers & H pipe won't hurt, but don't make a lot of improvement on stock heads...

Are you talking E6 or E7 heads and what pistons???

I'd say the only probable problem would be with the E7s and flattops(why I suggested checking clearance)... The E6 won't have a problem even with a .030 cut and 1.7s... Valves it those are DEEP in the head...

Agree, 7-10hp with 1.7 roller rockers. Mustang exhaust is adequate for e7 heads, which are the flow choke. You would be hard pressed to get 10hp on stock e7's even with long tubes. Also 1.7's are ok with speed density. Clearance should be checked to make certain on flat tops. Maybe one day, I'll check. :hick:

Yeah, the exhaust was just recently done.  Other than a better H-pipe with 2 high flow cats, I dont see any other changes coming for a good while.

So I'm guessing the 1.7 rockers are still the best bet?

 No if your guessing. Yes if your measuring. :D
