Performance rocker arms??


Recommended Posts

Posted

Are any higher ratio rocker arms made for the 3.1L MPFI, and if so, where could I go about getting them. I would rather do this upgrade than do a cam, a cam just takes too much time. Any info or ideas for other upgrades are welcome.

 

Thanks

Comp cams sells a 1.6:1 roller tipped rocker arm. i think its part number 1412-12. I think the 1.52:1 is 1413-12. The part numbers may be switched but It was easy to remember 1413-12:)

1413-12 was the PN on my 1.52 ratio ones. So im guessing you have it right with the 1413-13 being the 1.6. Ben, is there a big noticeable difference if one would go from a 1.52 to 1.6? Ive done H/C pistons, 2030cam, head porting, decking, and a few other things.

How hard is it to change rockers and what kinda gains can you get from them including what happens with MPG?

Changing rockers isnt hard, its just a nut that holds them down. The only annoying part is getting the stuff off to get the valve covers off.
