IF you have a ecu that's unlocked you can choose toggle injector banks during rpm reduction, one injector bank during rpm reduction mode or No Spark (No Dwell) When In Rev Limit or Stop Engine Mode, fwiw, Smitty

Your're running some good power. So your concern for the drives is legit. Bump that rev limiter up to 6200 and run it to 5800. The cam and springs can handle it :D

Wow. The 3.5 pulleys at 5800 rpm sound like something from outer space, I'm scared to keep it there long. Thanks for the set up, the engines are different animals this year!


I may crank up that limit and hit that same spot this weekend. I run a tablet for gps and the speedo app max speed memory only stays until u shut it down, need a screen capture of triple digits :)

There you go talking over my head again :)

Not a bad idea however, I didn't realize the rev limit could be applied to each bank

And again. A 4bus sighting sans skanks. What is this world comin to?

Thats a good point. 3.5 pulley your buzzing that 256. If I remember correctly, I think you have the older style blowers. They handle the revs better and have better bearing set ups than the Newer Holley versions. But I'd keep an eye on them. When I had my 575's, I sent them to TBS and had them re-done every 100-150 Hrs. Wasn't that expensive. You'll put chillers on it next!!

The sad part is it's just me and 4 girls in the boat the whole run, and I have no pics!

Yes the are the weiand blowers, I did the upgrades and taped the rear oil bath for easy access. I change the oil every 25.

I am running 120 stats no chillers, seems to work well. I have access to set a chillers, But haven't felt the need.

If I upgrade any further it's 871s and arneson drives :)
