It looked like the cracked area was raised up a bit so if it is, you had better at least grind that area down flush so there won't be a gap between your oil pump and the main cap. Check it with a straight edge and flashlight. Probably should use some red Loctite threadlocker on the bolt too.
I put some KYBs on my Duster and it raised the front end about 1/2 inch. I had to turn the adjusters back on the torsion bars to get back to initial ride height before installation.
I've never heard if one of the stamped steel rockers failing at that point where it's clearanced but my brother had a pushrod pop up through one of them using an oversized cam.
The one car I probably shouldn't have gotten rid of but it was in the 80s so I wasn't thinking about investment potential. I had a 1972 Demon 340 that I bought from a friend which had a spun bearing when I purchased it so I got a deal. I rebuilt the engine and drove it a while and the guy's...
I put the Comp Cams Magnum Solid lift 270 duration 0.468" lift in my wife's Barracuda and it is a great street/strip cam. It as a little noisy but you expect that with solid lifters, but gobs of torque.
I don't think you can fit much bigger than 2" to those early A manifolds. You have to use a tight fitting flange and barely flare the end so it doesn't bottom out and not seat on the raised cone. I used 2" for a couple of inches and transitioned to 2 1/4" kind of like step headers.
Make sure you test fit the exhaust manifold on the driver's side. I used an early A manifold on a 360 and had to grind down the area of the head that juts out by the rear head bolt so the manifold would fit flush on the gasket surface area. Only about 1/8" of material needed to be removed to...
Back in high school my brother and I both had 340 cars. His was a Dart Swinger, mine was a Duster. Both were 4 speeds. I always liked to let mine warm up a little before revving it up and taking off. As soon as his Dart would fire up, he would romp down hard on it three or four times and I was...
I ended up going with the McLeod diaphragm clutch with organic disc. It holds good but I don't like the pedal feel. It gives resistance at first and then gets easy to push the rest of the way down even though I have removed the over center spring on the pedal. It doesn't suit me for power...
If it only tics a few seconds, it would seem to me that's just lifter tick until the oil pressure gets to the lifters. I personally would avoid flushing if there's no visible gunk buildup in the valve covers.
I bought a parts car that had a 360 in it. It had broken the oil pump drive and lost oil pressure. The owner stopped before damage to the rest of the engine. I tore it down and opened up the oil pump. One of the lock wire springs had come out of a lifter and was jammed up in the rotor of the...
After I spun my first rod bearing with the stock pan on my 340 Duster back in the seventies, I have been going with deep pans and HV pumps ever since. I've never had another spun bearing (knock on wood).
