i'll play!! having used all three girdles in question, YES! they absolutely DO help. imho, they help in different ways, but they are a simple, reliable way of significantly improving bottom end integrity. the bcr girdle is a LOT of work to install. line hone is an absolute necessity with this girdle, as is some other machine work that may not be available in some areas. the chenoweth (sp) and 440source girdles are much easier to install, and typically do not require any machine work.
for what is the good life if not doing things thoughtfully?

I have a BCR girdle on my RB 493, very nice piece. Bought it from the original guy that started making the kits as he lived not too far from me and he also led me to moparts and for the life of me I can't remember his name.

What did the machine work cost to make the girdle work. Just curious about the price difference between BRC and an aftermarket block. The BCR kit is really nice if your in the 700+ HP range, but the cost of machining can add up. You need to find a machine shop that can align bore and hone the new aluminum caps to the block. My regular machine shop does not have the machine to align bore the mains, just hone them and when I called other shops I got several different prices. Then the bottom of the block (pan rails and top of caps) is cut flush too. Been awhile since I did mine, but I'd guess around $500-600 on the low end for machining, and $800+ at the higher end of the quotes I was getting. I paid in the low range, but that was one of those deals where a small machine shop outsourced the work to another shop with the equipment to get a better price. On my engine, I used the Milodon low profile pan and had no clearance issues with the K-member or steering linkage. On my 600 HP 440 stroker I am looking at the 440 source girdle because I want the extra 1/4" spacing for the Jegs 4.15" plastic windage tray.

Thickness has no bearing on the effect of the girdle, as it's intention is to eliminate "flag-pole" esk wiggle of the main studs, which attribute to cap walk and reverberation through the block eventually leading to cracks. It is NOT designed to influence lateral twisting of the block itself. You're the only other person I know who has ever put it that way, and it's EXACTLY why I decided to use my CRE girdle w/ my fresh 440 block that was already fitted w/ aluminum caps. The aluminum caps will still act as a "shock absorber", but the girdle should help keep the caps from doing The Wave. I suspect the studs getting moved around when not supported at the top is one of the things that causes that style of cap to crack when used only with main studs.
