Ok...my 87 iroc-z has Tuned Port injection, and the new style of motor with the centerbolt valvecovers...and the 86 iroc had the old style of motor...Can i fit the intake manifold from my iroc on the older motor or no??? the older style is readely accessable, and i was hoping all the TPI crap would bolt right up. Also, someone jacked my t-tops and my key, is $250 for a set that is brand new a deal i should jump on?i love my iroc, ive waited 17yrs to get it!

 

should work the big difference between the 86 and later motors and pre 86 motors are the center bolts on the intake 86 and later is at more up and down and the pre 86 is more at an angle

 

as for the t-tops yeah id go for it in fact i got a pair i could sell you if ur interested

 

right on dude, so what ya think about a 400 smally in an iroc? would it haul someass or what?
