yes i have. and i would still recommend the girdle over the cross bolts on a block that wasn't designed to have them.
Thats great! I am working on installing the cross bolted caps on three blocks that I have and I need some input. If you don't mind helping. I need to know how much prelaod there should be on the cross bolts(space between cap and block). And theory behind it . Thanks

FWIW, my 452's block has the Pro-Gram cross-bolted #2-4 caps. The shop that did the install recommended them because of indications of cap walk during a previous rebuild "way back when". Guess what? Even the Pro-Gram caps show signs of cap walk after being run at 600 HP, too.
Also, my installation has them going in as a press-fit, rather than having any side clearance where the block gets drawn in when tightened down. And those caps are a total PITA to remove as a result because they didn't have an provision for attaching a slide hammer to draw them back up.
My backup 451 block was machined w/ the old plate-style aluminum main caps back before I knew about the improved BCR and Best Machine versions. Since I know the plate-style design isn't ideal, I'm going to run a CRE girdle kit w/ 'em to help keep things strapped down.
And if/when time comes that I need to put my last core 440 block into service, I'll either pop for some BCR caps or just run a girdle w/ the OEM caps, depending on how I see things turning out w/ the 451.
I guess what I'm saying is I vote "No" on the Pro-Gram cross-bolted conversion deal and would try a girdle w/ the OEM caps, instead.

don't waste time with oem caps. the main benefirt of caps designed to work with a girdle is that they contact at their center just below the crank. when all is said and done, your stack up should be crank, bearing, main cap, girdle, not crank, bearing, main cap, air gap, girdle. i will post some pics today of what i'm talking about. also our girdles are 1/2" thick plate steel. alot of the other on the market are thinner and not as strong.

Certainly a nice kit but it's well over $1000 for one of your kits installed. Seems like a waste to put all the money into a stock block that could still crack.

The best possible setup is the girdle with aluminum caps, and having the caps milled to not require any shims or spacers for proper assembly. Spacers make it a Pain to assemble.
If you don't have a crankshaft yet, a center weighted crank puts the loads more where they belong, across all the bearing caps, not most of it on 2 and 4. My Mega Block had cap walk issues till I bought a center weighted crank.

i price our kits where i need to so they are profitable for me to make them. it costs money to produce the best kit on the market, not to mention having to keep inventory and market them against all of the chinese made parts that are a few dollars cheaper. it really all comes down to understanding the racing is a cost plus business. the faster you want to go the more power you want to make the more you have to spend. its pretty simple. i'm trying to provide the best stop gap measure for people before they have to upgrade to an aftermarket block. not everyone has $4000 dollars sitting around to put into a block thats going to make 600-800hp. thats where these girdles come in and they are cost effective when compared to the alternative. running aftermarket caps is expensive, since you have to have them line bored its just a fact. adding a girdle on there only adds a few more bucks into the build that will help increase the longevity of your assembly. unfortunately at these power levels the blocks do become the week link but thats not to say people aren't running successfully without an aftermarket block.
also i do sell part individually for people who want to upgrade in stages. the girdle caps are only 399.00 and you can have your block line bored and decked so your ready to install the girdle at a later date if you find out you have some cap walk at the end of a racing season. we try very hard to accomodate everyones needs and pass along good information so peoples racing seasons don't end early.
and in case you missed it we posted a sale on here at the beginning of the month for the girdle kits.
