jt1 Posted August 8, 2011 Share Posted August 8, 2011 I broke #2 & #4 mains at about 25 hrs run time on a 500 crank hp build, road race application, 2460#. Some of them run longer than that, some don't. The 2482 caps are better material than the 3412 caps if you can find them, but billet is the best way to go for a durable 500+ hp build. Sometimes you can switch stock caps between blocks, sometimes not, depends on the registers. If I was going to spend a lot of money on a stock block, it would be an 020, not an 010. jt Quote Link to comment Share on other sites More sharing options...
peej410 Posted August 9, 2011 Author Share Posted August 9, 2011 I can't find any around here. I found one 010 .040 already. The rest seem to be junk. I guess I have no choice but to go with SHP or GM OE at this point. Quote Link to comment Share on other sites More sharing options...
jt1 Posted August 10, 2011 Share Posted August 10, 2011 Yeah, it's hard to find a nice 020 block, and they bring a premium when you do. The best place to look is early 70's 3/4 and 1 ton trucks. When you find one and do a complete work over, you wind up with $1000 -$1250 in it, at prices around here. That makes a SHP look pretty good. The SHP's are fine pieces from what I've seen. About the only downside is they are about 20# heavier than a stock block. jt Quote Link to comment Share on other sites More sharing options...
