...holy cannoli - it's been a YEAR since we fired the Dakota's 440 - wow...that flew by fast...(vroom vvVROOOOOOOMMMmmmm) - IT'S ALIIIIVE!! 😃😎
Huge day yesterday - after about 5 hours of final checks (including realizing I had the dizzy 180* out 🤪), reading and re-reading the EFI instructions and trying to understand all of the small steps, and with 4 good friends over to provide several sets of extra eyes and wrenches, we fired up the 440!!; it lit up with authority and ran a full 20 minutes without even a hint of stalling, and nothing caught fire .
The engine seems to run nice and smooth, and it idles just like I wanted - zero lope - slow and smooth - sounds like a locomotive. I was hoping to be able to have it hover at/near 2000 rpm for a full 20 minutes for the cam break-in, and it did just that. I took a lot of time to to try to ensure all of the other components would also last the 20 minutes, and everything cooperated nicely - not a drip of anything anywhere. Thermostat opened right at 180*, and the big fan pulls hard through the radiator, and despite not moving and revving at 2k for 20 minutes the temp only got to about 215*...maybe 220 - not bad. Power steering temp came up to about 140, forgot to hook up the trans temp until after but I think it was just a little higher.
About the only thing that needs attention is the exhaust - things did get a little toasty, and I will need to address some areas...and depending on how it turns out I may have to eliminate the second gas tank to provide more clearance, which in the big scheme isn't the worst thing that could happen because I wouldn't mind it being quieter, and I'd have plenty of room for more effective mufflers. We'll see - I have a couple options, including sending the middle sections of the exhaust to JetHot, which will help for sure, and layer in more heat reflective insulation under the cab - the floor was too hot to the touch...and that's pretty hot. The section that routes up and over the driveshaft got the shaft u-joint pretty hot - not sure that's gonna work out.
Granted...2000 rpm for 20 minutes with no movement will get things pretty toasty, so we'll see hot it all does once it's rolling, which might be a while from now as there's several family events coming up and friends coming in for a visit, but like I've been I'll be chopping away at it when I can...but knowing it runs is a huge relief
Huge thanks to my long-time friend Ben for all of his hard work, particularly with helping me decode the FSM and 'de-computerize' a majority of the truck's under-hood harness and re-purposing the under hood fuse panel to now power the new systems. Also thanks to Trevor and Matt for coming over to help last night and keep eyes on 'everything' and to Mike for getting the whole 20 minutes on video, which I'll post up soon as I can edit it. And for sure, huge thanks to my wife and best friend Tracy and the kiddo's for all of your support and help throughout...yet again...another crazy adventure!
Ok - need more coffee... 😄
