big block help
hi i am looking at buying a big block for my camaro and building it over time im looking for about 650 700 hp but i am wondering if a 2 bolt main is ok or if i should stick with a 4 bolt ive herd of people running 2 bolts with 600 hp before but my dad says that back in the day that for real hp builds they only used 4 bolts i looking to have about 13:1 with h.o retagular ports heads or maybe some aftermarket ones and if my budget aloows some aluminum heads with a BIG cam and a few other things any info would be great
thanks logan
