so would it be better to go with a 4.500 stroke and 6.535 rod or am i going to have trouble fitting that in my 427T block, this will be the second engine i've rebuilt, the first was an international 345ci(stock rebuild), i want a 500+ci engine but if it's easier to build a 496 and the cost is less, i'll settle for that, what do you think?

Go with the low deck 496.
This way you won't have as many hedder issues.
If you want a 10.20 block go after-market and build a 598/632.

the motor is going in and 85 chevy truck with 4in suspension lift and 3in body lift i don't think i'll have problems with the hedders

well i built one with a 4 1/2 stroke like i said srp pistons are shelf pistons i have built many 572-632 tall decks. dart and world . bow tie. donvan tall decks .going with a 4.600 bore is where it at . the big stroke cranks fit better in all of them but the bow ties mark 4. i can not tell you if you can put a 4 1/2 stroke crank in your block ? how good are you with a die grinder? go to much and you will have junk. i happen to have some talldeck world blocks then you would have a 572 -598 with a 4.500 crank

I mildy proted a set of mopar "j" heads, i got a little to happy with the grinder and ran in to one of the valve cover bolt holes, so i'd say i'm not the best with a grinder, i'd like to use the 4.375 crank and .060 over 510ci, i don't want to go much bigger, should i use the 6.385 rod with that insted of the 6.535 and maybe shave the deck, 10.20-2.1875-6.385-.025=1.6025 comp height

well that is not a shelf pistons. a 1.645 is.it will not work with out working off the top deck off the pistons on a mill. so you are running customs .you could use the 6.535 rods that is up to you
