roller rocker ratio for a 4.6

[goincommando]

I have a set of 1.5 and 1.6 ratio roller rockers I'm wondering if they'll work for my motor.. any one help.. thanks

What are they from? I don't know of any roller rockers made for the 4.0L that were 1.5:1 ratio. Usually 1.6:1 or 1.7:1.

There chevy 350 roller rockers. I only paod 75 for them. But I might have a different ratio rocker I forget what ratio there are Ill check tonight

Unless you can do a whole bunch of machine work they won't work. You simply can't bolt on any rocker.

My brother works at a machine shop so Id have to drill the rocker arm bolt out and tap it to the arp size but I was woundering what ratio do I need.

[SilverXJ]

1.6:1 ratio. However simply drilling and taping the boss for a stud is not the solution.

There chevy 350 roller rockers. I only paid 75 for them.

Sell them back and get a refund. The 350 SBC rockers won't work on a Jeep I6,

SBC rocker arms are way too short from the pivot to the valve tip. You'd have to relocate the studs closer to the valve on a 4.0 head platform to get them to contact correctly.
