Okay...here is the deal. The block, heads, bottom end, basically long block 454 is from a 1995. The intake , distributor, thottle body, etc, is all from the 1987 454. Do I buy plugs for the 1995 or the 1987? How about timing...1995 or 1987? I would think 1995, but I wanna make sure /forums/images/graemlins/tongue.gif Should all of the stuff interchange pretty well? Its non vortec so I would assume they are both pretty much the same. Thanks! The distibutor cap looks a little beat down...I'm gonna get a new cap, is anything else replacable or that I should replace in the distibutor? Its got the coil mounted on the intake, not on top. Everything else inside the cap looks 'permanent'. Any help is appreciated. Thanks!
