I found a really good deal on a 427 tall deck (10.2). What is the advantage or disadvantage of a 10.2 over having a 9.8 or vice-versa. Thanks for your time.
Tall decks allow you to use a longer stroke without the worry of having the rods crash into you cam. Along with the taller deck, I believe, you can run a more aggresive cam, again, without worrying about the rods crashing into the cam. That if pretty much the advantage of a tall deck block. The advantage of a short deck block is that it's cheaper.Originally posted by jeepster34:

Well a tall deck block is an aftermarkey block, unless there's some factory tall deck blocks out there that I'm unaware of. Anyways, the block itself will cost more. As for parts, it all depends on what you will be using...usually is someone if using a tall deck block, then that means they'll be using a really long stroke crank, one that will not clear a short deck block. Longer stroke, more cubes. As for fitting under the stock hood, I don't believe you'll see much of a difference, unless you're using a really tall intake and/or with a spacer. If not, then I believe you should be fine. What will the potential motor be gong in?Originally posted by jeepster34:
Cheaper for the engine/block or just for parts to supply the engine? Do they still fit under stock hoods or do they require more room?
