Great info,after all the reading,I'm going to replace my cam.I'm running 5:71and 5speed with 20r,on 35's,runs great off road,falls on it's face at freeway speed.
From rpm charts,my set up is real close to same rpms as stock gears tires and 4 speed.
Hi Auggydog,
What cam are going to go with?
What exhaust are you running or going to run?
The reason I'm asking is because from some testing I've done recently with the 20R head, some cam profiles don't seem to show much change and could actually cause deficiencies in flow from the stock 20R cam, depending upon the exhaust system.... but that data is just what my software is showing after some quick tests. I'm not yet sure what is causing those numbers.
Gnarls.
