hello, ok iv been on here talking about doing a big block. well i just was able to get a 454 block. its a two bolt but i plain on putting arp studs in it. my question is should i leave it a 454 or should i do a 489 stroker? i realize its not that much of a price differince but i worry more about the clearance part. how much clearancing do you need to do? is it better to go with aluminum or steel rods? which clearance better? its not that much of a price difference but i dont want to do a lot of clearancing. thanks al.
