im using a blacktop head on top of a silvertop block.. tade apa apa pun :lol:
ur AFM depends on which head+throttle body+wiring u using. changing block doesnt mean u change wiring. so as long as u still using silvertop head and silvertop 4throttles, the AFM still there lor. jgn kacau it.
tip: if u are just dumping in the block buta2, check the oil pump. if u gonna use Blacktop oil pump (hydraulic tensioner), see that u use Blacktop timing belt (110 teeth). Silvertop tensioner is set & tightened by hand one, different timing belt (111 teeth)
tip: Silvertop and Blacktop water pump is different. it is very important to match SVT water pump with SVT oil pump, Blacktop water pump must be with Blacktop oil pump.
info: All 4A blocks are the same and can be bolted on to both Silvertop & Blacktop 20V heads. err... i think :lol: (correct me)
