In about two weeks it'll be time for spring break which means I'll have some time off of school. While most students will be out partying and having fun, I'll be in the shop hard at work building the new engine for my Dart. I hope to have it done in about four days. Pull the 318 out on Friday, build the 340 over the weekend, then install it in the Dart on Monday.
I will have a complete carb to pan 318 to use as a parts engine too but I have a few questions. The 318 is from 1968 and the 340 is from late '72. What WON'T swap over from the 'teen to the 340? I know most differences but I feel like I'm forgetting something. I have the 340 cast crank balancer and the timing cover with the marks on the drivers side. My 340 is externally balanced so I bought a counterweighted billet flywheel and had the rotating assembly balanced. I also know that sometime in 1970(ish) the crank pulleys changed. Is there any way I could use the earlier 318 pulley on the later 340? I've also got Schumacher motor mounts in the car now and I'm going to shim the drivers side mount to fit the 340.
I THINK that I am about ready to get this bad boy built and installed. This is my first time completely rebuilding an engine from the ground up and I want to make sure it all goes smoothly and that I don't run into problems that would bring the build to a halt. Since I have already done the slant six to V8 swap I shouldn't have many problems actually installing the 340. Building it is going to be the challenging part. The 318 has less than 2,000 miles on a re-ring so the oil pump, water pump, timing chain, fuel pump, and any other parts I replaced are almost brand new and will go on the 340 along with any components that will swap over such as the Performer carb & intake. Heres what I have for the 340 so far:
Machined '72 340 Block
Rebuilt cylinder heads-
Main caps and bolts
Shot peened crank- turned & polished
Oil pan
timing cover- timing marks on driver side
Windage tray
Resized rods with ARP bolts
+.040 Pistons
340 Balancer
Billet Flywheel
COMP Cam & lifter kit
Fel-Pro Engine Gasket set
Fel-Pro Header gaskets
Fel-Pro Collector gaskets
Oil pump priming shaft
Lucas break in oil- SAE30 6 quarts
Royal Purple HPS- 10W30 6 quarts
Transmission tailshaft plug
Mopar HEMI Orange engine enamel paint x2
Moly Rings
Clevite Bearings- Rod & Mains. Cam bearings already installed.
Intermediate shaft bushing
Wix Oil filter x2
COMP Cam assembly lube- 8oz
ARP rod bolt lube
Engine stand
Fuzzy dice
Thats what I got in addition to my running '68 318 that's in the car now. I want to make sure I'm prepared for this. I'm going to basically be living in the shop working on it until it's done.. I'd really like to get it driving before spring break is over. Nothing would make me happier than to cruise to class on the first day back in my 340 Dart!
Do ya'll see anything that I either don't have or can't take from the 318? I'm all ears.
Any advise, tips, tricks, or general knowledge I can get would be much appreciated.
Thanks FABO!
