roller rocker questions

[tayzoid1]

if i am not mistaken the factory rocker arms are a 1.6 ratio i have also heard of people using 1.7 rollers for alil more lift and less friction can i use 1.7 rollers and not run into any trouble on a factory head carbed 91 5.0 and would i see any real world gains in power or will i be asting 125$or more.

Is this with stock pistons?

an F cam and 1.7s will work.....but you should just save your money and buy better heads.

[EHardy1971]

If the car is stock,yeah,go ahead and put them on.It'll make a noticeable increase in power.

1.7 roller rockers do make a difference. But, I don't think it's all that noticeable though..imo. They will add lift which is good for a couple of hp. but where they really benefit you is the reduction in friction over a factory stamped steel rocker. Takes less effort to open and close the valves, which "free's up" a few hp and with less friction, you'll have slightly lower oil temps. It's a good, cheap upgrade - but since you are running an F cam, you REALLY need to check your piston to valve clearance when you do it.

[EHardy1971]

Ok,I missed the F cam in his sig.I would'nt do it if you still have the stock valvesprings.

the cost of springs and the rockers vs what you will pick up in hp gains aren't worth it in my opinion.

[tayzoid1]

i knew the 1.7 would add a lil more lift but you said it might touch the piston would 1.6's do any good i figgured the only thing im really going to notice is gonna be that extras lil lift but if yall say not to ill def. go w/ the 1.6 and new valve springs

[86nu]

its not guaranteed but for every .1 you change on the rocker its about .030 in lift give or take.

As stated above the 15 hp or so for the 300 bucks of parts doesnt seem legit, especially with the work in changing springs

save your cash and buy better heads....then be done with it

i got two sets of 1.7 for sale.

+ 1 million!!!!!!!!!!!!!

your cam is already has to much lift for your heads so why bother adding more lift? Stock E7's pretty much are maxed out around .470-.480 lift and not flowing any more air

Put that money in the bank and save for heads

i know gt-40's are better but should i just forgo the gt's until i have enuff green for some afr's or should i get the gt-40's if i can get a good price(300-400) ?

got a set of gt-40s 250.00 for 325 get heads and 1.7s that came on them from ford. cant beat that anywhere. hell add another 25 and you can have the cobra valve covers.

[EHardy1971]

Let me see if 03 DOHC (my buddy on here from the corral) might have a set of GT40's for sale.I got mine from him,and he's a good guy that won't do you wrong.:nice:

[tayzoid1]

what im sayin is would it be better to just wait and use the money im gonna use on the gt-40's to get the afr's that i want or would the money diffrence between the two not out weight the benifits?

Personally, I would save the money for better heads than the GT-40's. I'm far from experienced with 5.0 setups though.

Gt-40 heads are still not enough for that cam you have.

By the time you buy a set of GT-40's, have a machine shop install stiffer springs, and check for any repairs that may need to be made on them you are almost at the price for a set of used Edelbrocks or trickflows

[qkjuicedpony]

Get with coupe.

He can get you some aluminum heads that are decent and cheap

[tayzoid1]
