89 5.7 GTA
I was under the impression that all 5.7 TPI GTA's & IROC's were rollers.Removed the intake on my girlfriends 89 GTA to find this.Unless it's not the original motor.

Re: 89 5.7 GTA
All car engines went roller in 87. Even the trucks used the same block with a flat tappet cam. Pretty sure thats not original but just to be sure the last part of the vin will be stamped on the block on the passenger side water pump mounting boss. If its not there or doesn't match that will prove it but I'm 99.9% sure that its not original
