Was ready to rock about 4 o clock until I needed a coolant plug for the passenger side. Nobody in town even stocks them so I bought a sensor instead. There was so much coolant still in the oil I ended up changing to oil a total of 6 times! Took forever because I let it drain completely each time while the front of the truck was raised.

To my surprise it started up on the first click of the ignition! Holds an idle and even drives fine but I know it needs a tune before I go WOT.

Also it's still to quiet and this video sucks.

Thanks! It was definantly a thrash to get it together but I think finding all the parts might have been the worst part. Its depressing that a $100 difference between single vs dual springs just cost me over $1,000 but the bigger cam makes up for that! :Big Laugh:

Well made it to work without any issues it tried to stall one time but caught itself. I think I have an exhaust leak on the passenger side but other than that its great!

I do not know for sure. I want to say the PO told me they were 1219s but I was love-struck when I picked the truck up then drove for 20 something hours so my memory is a little shot. I am actually sending one out to a guy on PT.net and he is going to test them to see what spring they are. Then we will know for sure and I can not spread misinformation.

Why did you change yours out?

cause the cam gear broke off the front of the cam and bent about 8 valves.

then i replaced the engine

they were pac 1219X...they are actually still on the heads dont know if the heads can be saved. the springs i would prob reuse for a stock rebuild or something

Ouchy that was painful lol. You must have a nice parts stash.

itd be like sanford and son if i had my way around here, not really. about the only thing i want to do is build an engine/trans backup at some point so i dont have to leave this thing parked or on jackstands for months on end when something breaks

That's the direction I am heading. It cost a pretty penny to get kinda ***** heads fixed up in less than a day and parts overnighted on a weekend. Its funny parts locating is more stressful than engine reassembly.

definitely 90% of me building my junk is waiting on parts
