Ok guys, my dream 73 dart sport 340 is quickly becomming my nightmare. Lets do a quik timeline of events...
-Got 340 swapped in and running...drove great
-cut a transmission cooler line on a belt, blew oil everywhere
-fixed it, cleaned it all up, tried to go to a cruise in, about 5 miles away the car coughes stutters backfires like crazy and quits. Rollbacked it home.
-Talked to Don at FBO, ordered some stuff, took it apart, cleaned the floatbowls, cleaned it all, new needles and seats, tuned it all up, she runs great.
-took it out for a spin, got it home, it idled, choked up, backfired, and died. Cleaned the carb again, put it back, and it ran.
-Blew out a exhaust gasket
-Got a new one, didn't pull the header completely off, just loosened and retorqued.
-Took it for a drive with new aircleaner, ran great for about 2 miles and she started caughing and wheezing and backfiring and died. I got it restarted, and got it running enough to pull a u-turn and drive it the two miles home. I kept decent RPM and just kept the speed up so could coast is as far as possible. Got it to the barn door, it did the same thing. Restarted it, and limped it in.
-To top it all off the rear header bolt is now leaking coolant. I tightened it even further and it is still leaking. I can't pull that bolt out without removing the whole header.
Why the f#&@ won't this thing run right. The timing is correct, the idle mixture should be darn close. Here are what I know of the engine:
73 340
Stock bore and stroke
J-heads with 2.02s
Demon 650 mighty demon
Mopar M1 intake
Ultradyne cam est. 509 with 242 duration @ 50
Hooker comp headers.
I'm going crazy...and quickly running out of patience.
