520 FE on a simtester

[cattleFEeder]

Here is a video of my 520 FE on a simtester, being built by TMeyer in Fairmont MN.
Tim is a ford guy that does a lot of 351C and 400 engines.
My engine is a BBM block, cnc heads and their 2X4 intake.

So that's yours. Been following that build. Sure is a nice foundation. Should be a real nice motor.

I've seen the engine in person, it looks great.  Should be an easy 700 HP engine.  Tim borrowed a set of my headers, 2" primary Hedmans, for the upcoming dyno test.

I helped Cory out with some tech advice during the build.

When is it gonna be dynod?

This old hillbilly ain't never seen a simtester for engines before.

Pretty cool.

Maybe it's my old eyes, but it looks like the the cap screws that hold the  rocker shafts "squirm" a bit when going into lift. Didn't think that happened with the race rockers. Imagine how much the stock rocker hold downs would move on this motor.

Hope you're ready let-'er-rip soon!

Probably overkill for a street motor with 520 cubic inches and a solid roller 735 lift cam.
Dyno time my guess is next week and ready to pick up in 2 weeks.

No, certainly not overkill.  It's the spring pressure, not lift, that causes problems, and with any spring pressure over 600 lbs, I always look to the race rockers.  Too easy to pull the stand studs out of the heads otherwise.

Let us know how it does...

Simtester is/was a very common tool in the high volume rebuilder market such as Jasper or AER.
They usually ran a complete engine minus oil pan to check for oil flow and volume as well as for compression.  Makes it really easy to isolate bearing or galley plug issues and check for compression before completion and shipping.  Would have helped me on a recent build with a block drilling flaw...

I think the wobble is actually caused by the video compression and stabilization used by YouTube.
