Topic: Engine redlines and output

[Profile_Name]

Running a 20R with stock bottom end, and some LCE goodies in the head: dual springs, 1mm over sized valves, drilled rocker rods and .450 cam.

Running dual side draft weber 40s and EGR block off

What sort of new redline would i be looking at, along with power output, based on similar set ups?

Speculating on “LCE goodies” and “.450” cam specs, then pulling numbers out of my rabbit hat…

Around 5500 RPMs will be peak HP. You can redline at 6,000+ but the HP and torque will have dropped off significantly. 

*Torque will peak between 3300 and 3500 RPMs. 

“power output”…. being optimistically generous ….110 to 115 HP at the crank.   

Dual 40s are probably overkill on flow.    No EXHAUST mod?

Oversized valves may or may not help with flow.     

*Depending on cam profile, bottom end torque may disappear like a flea fart in a hurricane. 

Drilled rocker rods will suck at least 1 HP.
