615 vs 632 which is the best.

They cost the same so 17 more cubes and say 1.8HP/ci that’s a free 30HP.

Not a fan of a 4.600 bore in anything new.

LOL. Everything is 4.600 new basically. Still have plenty of room to grow/cleanup over the years

I didn't, Merlin max overbore is 4.625 per their website. One bad groove or ding, well your either at max bore or sleeving it. You also have more forging options on pistons under 4.600. More deck surface between cylinders etc, numerous reasons in my opinion.

So while you may not agree with a conservative approach its still a very valid point.

It's like my girl friend always says, BIGGER IS BETTER, same goes for engines, why do you think there is such a push now days for Pro Chargers, Turbos, Blowers, Nitrous, or just BIG CUBES.

Who cares about clean ups etc, make it as big as you can, sleeves are cheap.

That's why they created THESE:

Guess I just live a simpler life, to lazy and cheap to be working on and replacing blown up junk.

Lazy and cheap is the new American way for many. That said, you’re just speaking about something you haven’t a clue about.

I realize its tough for you to argue facts but what have I said wasn't factual?

The FACTS and the TRUTH is you don’t race a 4.600 bore bbc that as has been said is the norm today with bbc builds for fast top bulb bracket cars as well S/ST, S/C, S/G, TD and TS. Further, I have been running 4.600 bore engines since 2013. Further 2, I wouldn’t run anything Merlin.

Unless your running a boosted combo, 4.600 and larger bore is pretty much the norm in BBC bracket and NHRA TD, TS and .90 racing

Max bore on a block is just the manufactures suggestion. It's not set in stone exactly.
