Re: 1973 Trans Am Question
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: TORONADOXS</div><div class="ubbcode-body">I worked on a very nice '73 TA yesterday, did a rear main seal on it.. 455 auto, original engine. Anyway, the block was drilled and tapped (except one hole) for 4 bolt mains but it had 2 bolt caps. Was this normal? Why drill and tap them and then use 2 bolt caps, and why tap all the holes except one? I'm confused. </div></div>
Re: one untapped hole: probably broke the tool in that location. The inspection station is usually a few operations downstream, so typically you build five or six units with a discrepancy before it gets caught. Probably missed just that one (...or two...) K
