I am picking up a motor tomorrow...a .40 1967 289 ...fresh rebuild....forged pistons.....comp cam (don't know specs yet). I'm thinking a nice set of aluminum heads and a nice upper and lower intake....and a nice large shot of nitrous.....

what size is a .40 289? and are there any disadvantages to this motor? obviously it is not a roller block.....can I make it a rollerized block? This is going into Franky...Franky (89 coupe) has total tubular front end with no HVAC.....spooled rear with 3:73's..........thoughts???
