360 Crates
its all personal preference.. if i was starting from scratch i would do a big block with alumn heads,intake,water pump and housing. that would get the weight of the bb down and you still have a big block.... but thats me.. everyone has their own opinion on that....
as far as the mp short block goes. i'm running one in my dart and know quite of few guys in my area that run at atco that have had no problems at all with them...
mp 9.5 to 1 short block
6077 eddy heads
rpm intake
750 dp
good convertor
3:91 gears
instant low to mid 12's
a little weight savings and maybe a cam change and a little more gears.. definatley an 11 sec ride...
