I just picked up a set of 1.6 ratio roller rockers for my 92 L-98. Will these fit without having to enlarge the pushrod holes? Are they a true bolt on upgrade?

 

FWIW - When I was running that combo I had to enlarge the holes. I don't think this is optional. I was running a hot cam (.525 lift).

Perhaps others will chime in.

when i used the LT1 cam, i had no problems. http://www.fl-thirdgen.org/rockerswap.html

 

Im running an LT1 cam in my 305 with 1.6 rocker and with stock heads and after asking this questions along time ago before putting the rockers on, MRR23 replied and said it wouldnt be a problem and it ended up not being a problem for me aswell.

 

my buddy put on a set of 1.7s on his lt1

 

i'm running 1.6 RR's with an 94 LT1 cam and WP heads.no problems here.

 

I'm running 1:6RR with the stock L98 cam ....no problem

 

Can ya tell a difference?

 

You'll pick up a few horses sure, but I don;t know about noticing a difference without some sort of control like a base run at the track or dyno. Maybe 10RWHP on a stock 350... just a stab.

 

I'd be very happy with a tenth for a $75 investment and a couple hours.
