big blocks

I am thinking of starting a big block build. I have located a
(10069284 427t, 4-bolt, markIV, tall deck) Any information
on this block would be appreciated.

Thanks,
Michael Wallin

there is a lot of threads on this .headers may not fit.you will need a talldeck intake or intake plates and some work it may be better for you to start with a 9.800 deck block .but i have built the tall decks blocks so what do you need to know?? :whacked:
