1.6 rocker to 1.7 cobra rockers

yep they are the same and they work with the stock pistons!

you know, im only 20 years old, but i feel that i have a pretty vast knowledge of automobiles and engines and drivetrains etc.

but im still pretty much in the dark about valve work and most of the stuff that goes on within the heads. which is probbably the most important stuff.

if any of you guys know of a good site or book that can educate me a bit on roller rockers and all this jazz, feel free to post especially if it has to do with 87-93 stangs!

Stock cam and valve covers with 1.7 rockers will fit. You need to remove the baffle under the passenger side cover though.

Thanks for all your help!

Hey, I'm just a senior in highschool and in autobody. In a couple of months I'm going to college for paint and body. So I have some experience with automobiles. I have 1993 Ford LX mustang with the 5.0 HO motor. I have 40 series flowmasters, underdrive pullies, 3.73:1 gears, and a BBK coldair intake. And I'm thinking about putting 1.70:1 cobra rockers. How much horse power do you think I have? And how much horse power do you think I'll have after I put in the cobra rockers? Thank you ma'am/sir. I just want to beef up my mustang just a little bit more. My goal is 300hp

1.Are these 1.7 roller rockers the exact same? A.Summit Racing (CRN-44746-16 ). B. ROLLER ROCKER ARM | Part Details for M-6564-A50* | Ford Racing Performance Parts (M-6564-A50* )

2.Will these roller rocker fit on thes AFR 165 heads? AFR 165cc SBF Street Cylinder Head Part # 1472. (165cc Street Heads, Pedestal, 60cc 1472*)

3. Will the stock valve covers fit correctly with the roller rockers on the AFR head?

4.1993 5.0 mustang with stock cam and block running the AFR 165 head and 1.7 Pedestal roller rockers (instead of the stock rockers) with the increased lift be a problem clearing the stock pistons?.

Thanks :tongue
