- The 131ci Screamin' Eagle Stage IV Kit with the Cycle-Rama CR512 Camshaft is still a very popular go to choice for many customers looking to go fast.
This time however, CR512 Camshaft was on backorder during the build process & the customer could not wait. So I trialed a new Camshaft I hadn't used before....The Rocket Cams 544.
This 544 Cam requires a higher compression ratio than the stock 131 engine straight out of the box so I'm expecting it to be a little soft off the bottom & maybe a decrease in expected HP.
The reason I am not bumping up the comp ratio is because when the CR512 gets installed the comp ratio will be too high for that cam & it will sacrifice mid to top end performance.
A few other bits went into this build with the Alpha Performance Engines 'Hot Up Kit'. The hot up kit includes, Cycle-Rama Billet lifter cuffs, a hand ported & textured 64mm intake manifold, A.P.E High Capacity lifters & it also comes with the CR512 Camshaft. So if you order the Hot up kit you will get the CR512, it was just unavailable at the time of filming.
The fueling OE+ Cam plate went into the cam chest for some added security & strength. The upgraded Cycle-Rama Compensator Ramp was also installed with this build.
Also on back order during the time of filming is the full header system from RINEHART, so for now it is just running the factory header setup with RINEHART Slip on's.
Thanks again to all my viewers & subscribers!! I do all this for you guys!!
I do my best to get you guys some great first hand professional insight into what's involved with these builds.
