Take these numbers given as examples with a grain of salt. The come from different measuring devices with probably questionable calibration (no offense intended). You need a proper size micrometer (not caliper) that discerns down to 0.0001" to accurately determine if your crank is in spec. A...

Unless you just want to have the W2's to say you have them, I'd re-use the Edelbrock heads and have them worked over and maybe taken out to a 2.05 or 2.08 valve. The W2 have more potential but they need to be ported as well to take advantage of it. The bespoke rockers/intake/header flange all...

Like a lot of the stuff in our tool boxes, when you need one, you need one. My dad had one of these nut busters that I remember using on a 39 Pontiac four door we were hot-rodding 35+ years ago. I thought I got it when we cleaned out the house after he passed and Mom moved. I guess it fell...

Bearing spacer shims take the 360 bearing bore down to 340 size. Not real common but they are out there.

Yes I have. I'm hoping to get some real-world, been there done that feedback from here. So far I haven't found any substantial reviews of the cheaper hydraulic? type load cells in my searching.

Anyone use and have a recommendation for a more affordable valve spring tester? The "good" commercial ones a shop would use are near $1000 new and used versions about half that. I'd be a lot happier around $100-$200 because I'm only using it for my infrequent needs. I have a mill, drill...

That should be a nice cruiser. I’m interested in what slave you use and how you mount it. Take and post some pics when you get there if you don’t mind.

Looks pretty nice. You'll appreciate the weight after 100 rounds or more in an afternoon. I know I tend to get a little flinchy after 50 shots or so with my Peerless field gun, even with the lighter 1oz loads.

These appear to have the threaded spacer welded to the top of a standard head bolt. I can think of two or three ways to accomplish that with a standard Mopar head bolt that would have minimal effect on the strength of the bolt.

If you are going through the cost and effort to change the heads, why would you not put in a new cam that can actually take advantage of the potential increase in flow? Seems like the definition of a half measure. Even with the lower compression of the 72 piston, I would think that the bigger...

DIY rotary engine….

My '71 motor which is standard bore and hasn't been decked as far as I can tell had the pistons at .023"-0.34" above deck, so I think you recall correctly. Some of that variation is in the factory machining of the pistons, rods, and block as well as the regound crank it has. I was planning on...

Cone or clutch type Sure-Grip?

Out of curiosity, are your above deck measurements in line with the pin, or worst case tilt at top or bottom of the piston? There isn’t a huge difference, especially on fresh bores but I think I saw a few thou on my worn bores

The '71 340 in my car has been rebuilt but is still standard bore (with a little wear) and I assume standard deck height. I found my pistons are above deck .025-.033" but pretty consistent on each bank. I wanted to put a set of small chamber aluminum heads on but going from J-heads to aluminum...
