Thanks for the advice,Cab!...will do! Here are the pics I promised. Wish my darn Sony would take better pics! You can still see the "evidence" of cap walk...and metal transfer!

another!

the block surface!...sorry for the clarity...or should I say,lack of it?!!!

They've been bouncing pretty good. Studs will help a little. If you intergrade all the things I mentioned you should be OK. Personally, I would put alloy caps and studs on for 600HP. Some shops line-bore machining is done well enough that a hone is not necessary.

i put ductile iron main caps and ARP studs in my 512 motor with the iron heads, the first inspection after dyno testing and some street and strip driving, not a lot, I found similar results I file them flat and put it back together, I swapped heads also and ran it the next year a lt more at the track and on the street. I looked at it agian the next winter and had a little main cap wlaked, not near as much as the fsrt time. I swapped the 4.250 stroke crank out for the 4.300 stroke crank to increase the compression from 9.25 to 1 to 10.29 to 1 by moving the pistons up from -.025 to zero deck I had all the main caps off that motor at the begiining of last year and I didn't need to file the caps anymore, I leak it down last month and put it on the dyno, it made 728 HP on pump gas at 4300 ft. elevation I put it back in the car for another year of playing Same main bearings for five years now

Yeah,Shawn!...same thing I was thinking when I looked at them! I'm REAL surprised the bearings looked as good as they did. They could actually be re-used..but won't! I might just look into the Aluminum BCR caps..they look to be a stout piece. Combined with ARP studs..and EVERYTHING you mentioned previously...I think would do the trick,quite nicely!

Heres a trick, when you put it back together!!!!! Get some spray moly, it drys in a couple of minutes. It will provide a high preasure lube to let cap walk, without metal transfer!!!! Also get the rotating assembly balance, and also check max timing!!!!! Advance coming in to quike will do it to!!!

Thanks for that info,Dwayne! Will I need to do that with ARP studs...and SD Concept aluminum caps? I'm leaning pretty heavily in favor of the old BCR-design billet caps!

No you should install the alloy caps dry. That being said never tried it any other way and we have zero issues.
Jerry is shipping caps and girdles this week thanks for all of your patience guys

Greg

that is correct, definitely install the aluminum caps dry. and greg is also correct the cap and girdle kits will be shipping this week. i have standard aluminum main caps already boxed up and we've already sent some out.

Jerry..please contact me ASAP! THANKS! Randy B.

Got a call from Jerry,the owner of SD Concepts...who are now making the BCR aluminum main caps. He invited me to take a tour of his facility..which is approx. an hour from my house. I plan on taking pictures..and will be posting them that night. Most likely Thursday evening. I plan on stopping by his shop on my way back from Detroit..Thursday afternoon.

I also have the 440 source billet steel caps. They did take some machine work to make them fit. Seem to be working.

Thanks for posting Randy, also i wanted to put up an open invitation to anyone on the board who may want to stop by and check out the caps. we will most likely be hitting the show circuit next year and hitting most of the major mopar shows and if I can't do it by myself, hopefully at least a distributor will be there.

we will be introducing the billet rear main seals next week. following that we will be reintroducing mopar billet fuel rails for small blocks and big blocks and the new and old hemis. we used to sell a ton of these every year, and will now be getting back into them.

we also have an upgrade mopar serpentine belt kit for the big blocks out. the new one will be made from 6061 aluminum as the cast cores we were using are getting almost impossible to find.

small block serpentine belt kit will follow.

mopar specific 4 bbl and 2bbl (six pack throttle bodies are on the list in early summer.)

and we are always looking for additions to the list that people may need or want. our website will be back up soon as well.
