On my 505 stroker pump gas engine I used the BCR girdle ,aluminum main caps, ARP studs. Block is 1/2 filled. After 8 years of running close to 1,000 1/4 mile hits the block wasn't cracked, no cap walk . If it last another 8 years I'll be to old to get in the car, well maybe out of it.
it's ok to butt heads, just don't do it with a butthead
