Spent the weekend on the dyno programming the Holley HP EFI for my 454's.
This a graph of dyno headers w/ mufflers no flame arrestor vs CMI E-Tops and flame arrestor.

Made it out to the boat for a bit tonight. Installed new steering fittings and new stainless hoses.
Also solved the problem I had earlier of not being able to reach the nuts on the back of the upholstery inside the freeboard.

The stainless hoses look very nice on there and I did the same thing with the speaker hole myself. There was no way I could reach that nut up front on the panel stud. I bought new steering hose and chrome plated brass fittings for my steering as well. Also sent my brass 90's to the plating shop and had them chromed. They were super inexpensive @ $4.00 each to plate, because they can run them with other jobs. I you ever want anything like that done let me know. and I will put you in contact.

I'd love to get chrome on there, but I might not even have enough time to get my throttles redone. Once summer is here I might lose interest and just break out the Panther. lol

It's funny you mention throttles... I had my throttle base plate and knobs refinished and I polished out the chrome handles. Finally got around to assembling them and saw the new billet Livorsi cant forward controls and ended up ordering them. Mine sold within a few hours and brought almost what cost is on new ones.

Looking very nice Jason! I wish I was as far along as you are.

Thanks Heath!
Got a little sidetracked. Had to do a quick emergency re-bearing on the 2nd engine. (non dyno'd engine) Saturday night, while the oil pan was off and I was replacing the cam on the engine. I decided to take a quick peak at the middle main bearing. To my surprise it looked terrible. (<20hrs on rebuild) I tore it down Saturday night and had it back together Tuesday night. Last time I had run the engine was the end of 2019. I was running up river at Hot Boat and threw a sea pump belt. I noticed the engine was a little off. I looked at my gauges and my water and oil temp was around 230-240°F. I shut it down and idle back on one engine. Brought the boat home fired it up and winterized the engines. Everything ran great during the winterization and I thought nothing of it it again. While the engines have been sitting in the shop while I painted and transom'd the boat I did a leak down. They were 8-11% cold and not fired for over a year. I also cut open the filter and the pleats were clean. In the bottom of the oil pan there was a black sludge and that drew my curiosity to pull the main. I have never seen any sludge in one of my engines.That Oil was toast!
I can't wait for this Holley EFI with all the alarms and limp modes to protect an engine!

What got that rod journal so hot? Old failure or been welded on?

I assume old failure/repair from previous owner. I believe he mentioned it before I bought it. My machine shop checked it out before they balanced it with my components. They said it was true and had no issues with me running it.

Second engine on the run stand and all wired up. I flashed the 2nd ECU with new firmware and loaded the Master dyno file from the 1st engine. Will fire it up tomorrow and break in the "refresh" and hopefully have the engines in this weekend.
