Reading about the sportsman blocks capable of handling between 700-900hp. As I am only expecting to make about 500hp from something like a 393 engine, is there any need to go to one of these blocks, and also should you fit four bolt mains, or a girdle if you want to rev to around 7000?

Money will dictate the outcome, I have looked at Dart Iron Eagle and the alloy block, RDI Alloy blocks, apparently all the weight saving is about 60Ibs on the RDI 427 over the cast block. The bottom line is if I where to find a block around 68-71 vintage and fit a girdle line bore etc from what a lot of you have said it should never give a problem?

I am a perfectionist with out the resources, but have patience, and can't wait to get out on the track!
