It feels good to be kicking up some dust with this truck again. For those that haven't read about it in the past, this is a 1972 Highboy that dad bought from the original owner back in the mid 70's. Here's a link with a few details....
http://fepower.net/simplemachinesforum/index.php?topic=620.msg4771#msg4771I'm about ready to start building the 504 short block. My machinist is balancing everything this week.
Here's a run down of the short block:
Early Genesis block
4.375 RPM crank
6.7 Scat I beam rods with ARP 2000 bolts
4.280 CP pistons (thanks Blair)
Comp 306S cam
Schneider shell lifters with Hi-Lube feature
Cloyes Tru-Roller timing set
Professional Products harmonic balancer
McLeod 30lb flywheel
As usual my fun bucks ran out before I got everything scratched together. The original plan was to get a set of Blair's street Pro-Port heads. Along with T&D street rockers and solid roller cam. I did buy a Bullet solid roller cam from Blair when I bought the pistons but that was as far as I got before life happened again. So for now I'll have to run the heads and intake from the 390 on the 504. (but I still want the intake adaptor Jay, I think I'm #86?) The heads are C4AE-G's that Les Schmader ported with 2.15 and 1.65 valves. The intake is a Performer RPM that I port matched to the heads. They should choke the 504 cubes pretty well.
Maybe the tax man and uncle Sam will cut me some slack.
Here's a short video I took with my phone before I pulled the engine last weekend. It's kinda shaky so I apologize in advance for any motion sickness. The old 390 still has quite a bit of punch left in it. Gets the 5100lb truck down the road. I'd like to find a Pinto wagon to turn into a drag car someday. I think the 390 would be just right for that.
The 390's last song.....

We had a bet wether or not the cherry picker would go high enough. The loser had to fetch a couple of slushy beers out of the fridge.
Here's what a Schneider shell lifter with the Hi-Lube feature looks like. You can barely see the ground flat that runs from the bottom of the lifter to the oil band.
Has anybody ever seen or tried a lifter like this? I'm wondering if 16 of these things are going to result in a low oil pressure situation. They seemed like a good idea considering all the wiped lobes that I've read about. I guess I should have asked before buying them. What do you think guys?
