Ok I looked but could not find what I was looking for
I done a up grade on a 36 prodrive head cam piston carb ect.

The rpms are 1200 in neutral and 1100 in gear and tops out at 4200 is that good ?

I was thinking getting 4700 rev limiter rpm but It took all I could to get it to hit the factory rev limiter. Is this normal ? The speeds are one guy 30 two 25 THANKS FOR ANY HELP

something is wrong with those mods you should be running better than that.

How was your trim. That has a lot to do with it. I run 4650 no problem with the mods I have even with a load and new prop.

Something isn't set right. I could turn 4600 with a load with heads, cam, carb, and exhaust.

I have a stage one and I am all over 4700 rev limit. So you should be doing way better than that with those mods

You sure your governor is locked out maxed? Something is wrong if you can't get over 4300.

I have an 1851 Excel and ran 4300 with 5 people with a hammer prop this weekend.
