I would have said 0.055" over for 4.375" bore because there is a good selection of pistons and rings in that size, but you said it was already 0.060" over.

should be fine. Sonic check the bores will give you more information.

Try it at the recommended 106 degrees, you have the gear and converter for it.

Look at the shift kit instructions for how the throttle valve / spring assembly goes into the valve body, and also the gap between the throttle valve and lever stop.

looks good. make sure to use matching valve springs

If a re-ring will seal it up, run the low compression and a high stall converter. Sounds like it's just until the other engine is done.

need to inspect the parts, but if it is in decent condition where it is more of a re-fresh than a rebuild, then most rebuild kits will supply all the gaskets, seals, and sealing rings. You need to make sure it is correct for your year transmission. Many kits will have seals and rings for...

Max lift don't matter in piston to valve clearance. Max lift is at the intake centerline, usually around 110 degrees crank rotation, so the piston is way down the bore at max lift. The closest points are around overlap when the piston in nearing TDC the exhaust is closing, and when the intake...

Correct. That just give a known starting value. Piston position down the bore can then be calculated for each degree of crank rotation. Cam grinder should be able to calculate lift around TDC overlap (with an installed ICL position) to have a good idea of what P-V will be. You can do these...

Depending on which "stock" pistons are in the engine, the larger cam might have piston to valve clearance issues. My 383 was rebuilt with the forged flat tops, but also the engine deck was milled so the pistons were just slightly below the block deck, and my heads were also milled 0.040" for...

I think the 3-prong switch needs the valve body rooster comb shift lever that has the plastic guide part where the switch is. The earlier single connection NSS switch, I don't think has the plastic guide. If not the switch, the plastic guide could also be broken? A-727 Detent Lever Plastic...

I removed the restrictor plug. My transmission shifts fine without it, but it uses the steel front drum sealing rings, not the teflon sealing rings, so it might have more leakage? That bottom package with the small snap ring looks like it might be for the rear servo where shift kits place a...

Sounds good, did it just sit with water in the cylinders? might try heating and cooling with wax?

If the pistons are that stuck, how bad do the lifter bores look?

Remove valve body and inspect it for cracks in the circuit walls. While VB removed, air test clutches and servos. FWIW, I had an issue where I lost 3rd gear, and found one of the fluid circuit walls in the valve body cracked. I was 200 miles from home at a friends house, and I JB welded the...

Nice paint! Back in the early 1990's I ran into thoughts like this. I had over-reved the original 383 in the Charger and bent a few valves. At the time, Koffels had recently introduced the B1-B/S heads, and thinking the small 65cc chambers would give the 383 a compression boost. Then started...

Hughes still offers the "No flat can guarantee" if you use their springs and break-in oil: https://www.hughesengines.com/TechArticles/ourcamsareguaranteednottogoflat.php I also recommend their lifter bore burnishing ball to make sure the lifter bores are round and sized correctly...

Budget wise, If the 346 heads have the original valve springs then you might want to get a set of 440 source valve springs they use on the stealth heads for $50 a set. Using a mild cam around 215 to 220 @ 0.050" makes things easier if the car is not setup with a high stall converter, also nicer...

My first set of MW victors was when they were first released, and I broke the rocker stands, so milled the stands off and used MW rocker stand blocks. Mopar Max Wedge Rocker Stands Second set was the CNC ported heads and they were a newer casting with more material around the stands and on top...
