When does money outweigh sentimental value? 1968 notchback build thread

-
His son told me.that his dad showed him a hot wheels car.and said I'm gonna build the dart to look like this car.and pop some nice wheelies.
 
So here's some updates. We'll see if I can pick up where I left off. EDM lifters, spent some time checking rotation and finding bores for each lifter. You can see my paint marks in one of the pics. Turned the engine over by hand a lot to make sure the lifters rotated. Checked the oil pressure with a drill. That went well, other than my oil filter block plate leaked at first and made a mess. Had some rocker oiling woes. Couldn't get oil to a few rockers. These were supposedly NOS erson rockers and still had what seemed like cosmoline on them. I thought maybe the grease on them was clogging up the oil holes. But upon disassembly I found a chipped race and a needle bearing fat add falling out. Found the Torrington number and reordered and reinstalled.

Some Smith Bros pushrods and oil up to all the rockers. And a Milodon valley tray installed.

Installed the intake next and pulled a vacuum on the cooling system. Had a little leak. Little enough I couldn't hear it. So I had to rig up the radiator and pressurize the system. Turned out to be this little guy. Leaking from the nut retaining pin? Don't even know how that's possible. New one fixed though.

Finished the rear main harness wiring. And used an empty pin in the connector for fuel pump wire so everything is run within the same harness.

Converter from Edge racing converters showed up for the 42rh. Andre was awesome to deal with. Quick turn around also.

Car is going to be a nice one, you keep at it that is for sure. I mostly work towards building race cars.but you keep my attention with this barracuda.looking forward to seeing it with the red bullet in the hole. that is alot of work restoring the car to that level. Never heard of edge converters, going to check on that. I have always used turbo action.keep.the updates coming
 
Fabbed a bracket for my hyperspark ignition box, solid state relays and bus bars. This all slides into my fake battery box. I'll start wire mock up when the engine goes in so I know where to terminate wires.

Here's something I noticed with your grant steering wheel kit. The metal shroud behind the steering wheel that you have is actually for a 1970 up locking column. I ran into that with my 67. You can see the shroud for my 67 sits at the right diameter whereas yours is larger than the column. My guess is they sold you the wrong kit. It will bolt up ok, but the shroud is for 70 up with locking column. Grant# 4313 is the kit needed for your column, they probably sold you Grant# 3314

Here's pix

That's funny, That was my only gripe when I got it. I didn't realize they made two separate Mopar kits. Thank you
 
Here's the engine ready to go to the Dyno for break in and a few pulls. My reasoning is that I'm running a Holley Terminator stealth and Frankensteining the Sniper Hyperspark ignition to work with the Terminator ECU. So, I don't want to have issues at start up that may involve over cranking and flattening the cam. So I borrowed a buddy msd distributor and carb for break in.

Here's getting set up on the Dyno stand.

Got it dyno'd. Spent 7/1 getting it on the dyno stand and broken in. Made a couple 2-4k pulls today checking vitals, then changed the oil. This afternoon we made some 6K pulls.
Like I said above my main objective was break in a solid flat tappet and not max power. I didn't want to have ignition issues on first startup for fear of flattening the cam. So I wasn't tuning for perfect fuel ratio, timing curve or whatever. It's all changing anyway. We set timing at 36* and afr was 11.9-12.2 for the 6k pulls. It was nerve wracking enough! Holy crap is it nerve wracking!

Engine specs.

Short block:
360 based 414
4.06 bore
4.0 Molner forged crank
6.123 Molner rods
Mahle inverted dome pistons 16cc's
.276 top ring down
~ -.002-004 in the hole
10.87-10.89 compression
.040 custom Cometics
Quench .043 not sure on an inverted dome?
1,1,2mm ring pack .016 top .020 2nd gap
King bearings throughout
.002 main clearance
.0028 rod clearance
1784 bobweight
Arp main, rod and head studs
Milodon road race pan and pick up
Modded windage tray(due to stud clearance)
IJ crank scraper
Melling 72HV(used lol)
Mopar magnum one piece oil pan gasket
MP .557 cam 4* advanced at 106*
Rollmaster billet chain
MP chain tensioner
Flowkooler water pump
Side entrance rear freeze plug cooling
Trick flow balancer internal

Top end:
Howard's EDM solid lifters
Milodon valley tray
Smith Bros custom 5/16 ball/cup pushrods
Erson 1.6 roller rockers
B3re geometry correction
Billet rocker hold downs and studs
Lashed to .020/.024 hot
HD distributor gear/pump drive
A crap ton of driven assembly lube
Trick flow 190 heads
Mopar M1 modded intake (burr finish(done by me and probably a hindrance ,I'm not a pro), epoxied to square bore, back passage coolant lines.
Hvh super sucker (left on for every pull)
Autolite 3924's
A friend's msd distributor and wires
A friend's Holley 750 set up for his 408.
Mix of 91 and 112 unleaded. So 95 octane?

Results:
Dyno's onsite weather station
5200 foot elevation
90* today
25.7 in
42.3 relative
546hp/557tq corrected

Thanks,
Keith

Here are the pictures of the oil change. This is after break in and the 2-4k pulls. Used Joe Gibbs 5/30 break in oil and a bottle of zinc along with a wix filter for both break in and refilled with the same for full pulls. Cut the filter open and inspected the drain plug magnet. Everything was super clean. What I thought was a big chunk of aluminum was just some congealed assembly grease. So that was nice.
