Okay so my springs (if all goes as planned) are going in tomarrow, and while i was taking off the rocker arms tonight a thought passed me....I could save up the 300 bucks and go with the Crane 1.6 gold RR, OR go to my local chevvy dealership and buyt 16 of the LT4 1.6 RR and get the same performance.

Which route should i go???

What are the advantages of getting the Crane. over the GM performance parts RR???? (and are the Crane ones any lighter???)

Are there really any differences between them at all (asides from colour?) I mean after all the Gold anoidized Crane RR were designed to mimic the LT4 RR were they not???Atleast thats what it says in the jegs/summit catolouge as a description for the Crane 1.6 RR.

*Also anyone know the GM parts direct PN for the LT4 RR???(i looked on Shoebox's PN page but couldn't find it)
Thanks!

*EDIT* Also by running a 1.6 RR ratio that'd bump up my lift to like a .544 total, will i have any Piston to Valve clearance issues????

 

I have read that the GM rockers ARE Crane rockers, I'm not sure if this is true, but they sure look the same. The GM rockers are just as good as Crane in my book.

 

I'm 99.9% sure that the GM rockers and the Crane Gold rockers are the same. The part number for the GM rr's is 12370839

 

The GMPP 1.6 LT4 roller rockers and made for GMPP by Crane. Hope that clears things up. I got mine from Jason Cromer for $259.

 

Both crane golds and gmpp 12370839 are made by crane. There is a difference other than color. Slots on top of the "gm" parts were reduced making them stronger and allowing a slightly lower lift than the regular golds.

 

Jay got you the rockers for 259? Wow so I guess the Hot Cam kit is a good deal for 470 then.

 

Sounded like a good deal to me, Ive got the HotCam Kit from Jason going on, Jet hot headers, mufflex y pipe, Spec clutch, and aluminum driveshaft, hope I can tell a difference when I get it back on the road next week.

 

how about this... dont buy either of them, instead pick yourself up some comp cams rr's and have peace of mind

j/k, personally i love my comp cam's rr's but i have a buddy that has cranes in his car and they seem to do the job

 

whoa over half of the price of the hot cam kit is the roller rockers....thats insane

 

Yep, Jason sells the cam for $173.

 

No you will not have valve to pistion clearance issues.

 

wtf
he said no you will not.

I concur.
