I NEED 1.7 OR 1.8 FULL ROLLER ROCKER ARMS

[project60degree]

im looking for 1.7 or 1.8 full roller rocker arms that need minimal mods to LIM or valve covers...i have gen 3 heads w/ guideplates somebody please just give me a straight answer, somthing off the shelf with 3/8 studs, if any one could help me i would highly appreciate it

there are none for these motors, just 1.6. anything otherwise your gonna have to make it work.

Agreed they do not exist. Rocker arms for a standard SBC (not an LS or modern Vortec) should work. I think Scorpion may have 1.7. Be careful when buying rockers they may have different distances from the trunion to the tip.

when u say i ahve 2 make it work what do u mean?

its uncharted territory. if it doesnt all line up, you'll have to try some tricks to get it all to fit correctly. like if the roller tip doesnt sit in the right area of the valve stem, but the geometry is correct elswhere, you'd have to move the studs (sort of offset drill the holes for the next size up studs, moving the stud a little further or nearer the valve), if possible. the only way to know, is to try it the hard way. some people have used 1.6 rockers from sbc's, so i agree with the above, start with sbc family and not ls. Its a shot in the dark for anything over 1.6, you can either be brave, or abandon this.

i do believe not, 100%, that you can use rockers for an 87 camaro 350 TPI with center bolt rocker covers. my dad ordered a set of 1.6 roller tips that looked identical to the ones i put in my 94 Z24. i think you can find a set of full rollers of 1.7:1. you'd have to ask crane cams.

Yes thats what the Crane 1.5/1.6's are, Narrow Body rockers which are the same centerbolt style. They have to be this narrow body style due to space constraints.

However if using a full roller body rocker, You need the Crane conversion studs which have the proper M10 head threads, and the 3/8ths upper nut threads for the rockers.

Otherwise for Stamped steels you'll need the old GM 476530 stud and M10 jam nuts for adjustablility.
