We’re almost done with the build of our 1800cc stroker engine and with our compression ratio and deck height set, we can set up the geometry for our 1.4 to 1 Ratio Rockers. We’ll use cut to length pushrods which are needed whenever building a stroker engine or when using high ratio rocker assemblies.

Thanks for sharing these informations!! I have a channel on YouTube as well and I was not sure how to cut the rods and install the ends (I thought it was necessary to heat to install, but it is not). Congratulations for the video!

I'm guess I'm old school I prefer the swivel feet.

Great video, I have a 1904cc with C35 cam and a 74mm crank, GTV-2 heads and stock rockers with Scat swivel ball tappets and stock length steel pushrods. Is it okay to just use shims? My geometry looks good with four 0.030 shims or should I shorten the pushrods and use less shims?

[toddavies]

I’m assuming your starting this process at cylinder 3 also for filming purposes

Do the chromoly push rods make more noise when the engine's hot ?being they expand different than the aluminum? I'm building a otherwise stock 1600 bottom end with slip in 88 thick wall Pistons IAP outlaw 90.5 heads with 40 mm intakes 35.5 exhaust stainless steel valves single rev springs and don't know what push rods to pick to use with the IAP 1:4:1 ratio rockers oh yeah I'm going to be running dual kadrones& and a kultek black oo9 electronic dizzy and thick 409 Taylor ignition wires any info on what push rods to use would be great 🤠

Are the springs stock or single high rev?
