theres a couple brands..

what ever you do if you plane to make over 1k for power i would def go to a 4blt front cap also and not just splayed middles..due to the fact these blocks tend to beat the **** out of the front cap bearings in big power apps

I used the eagle splayed caps and you could definately tell that some were harder than others during the align bore. One was fairly soft and the other two were hard as hell. Either way they are cheap and will get the job done, I don't have any gripes with their quality

just search for pro gram or pro lite billet caps..they are also who im going to go with when ever i do my block..they are the ones who make the front cap a 4blt also.
http://www.pro-gram.com/catalog.jsp
sbc mains are 2.30,2.45 and 2.65.. your block should be a 2.45

283,302 and some 327s are 2.30 mains
305,350 are 2.45
400 are 2.65

I used the Eagle on my latest build, used the Milodon in the past, between the two the Milodon was better quality. The Eagle set I got did not have washers for the splayed bolts. But the machineshop did a good job installing them.
