Highly recommend if you need to drill a second hole for the alternator bolt on a GM truck engine that doesn't have one and you are swapping one into a car that needs that threaded hole to mount the alternator bracket (i.e. f body cars).. made things alot easier

This lays out the hole to be drilled right on the money. I used this on my truck block to drill it for a low mount alternator and everything bolts up perfectly.

We have used same template, bit and tap on 4 iron 6.0’s all fit perfect, it won’t fit as good if you have milled heads but we got it to work on one with 20thou milled

I bolted this up to my 5.3 block. Chucked up the right size drill bit. Only to find the hole on template smaller than drill. It made me double check the drill size b4 I destroyed the block. It was all good. Lined up the drill and drilled out template then into block. Template worked great.

I wish I knew these existed before I tried tapping the block without one. I ended up butchering my iron block two years ago. This will definitely help.

Excellent product. Fitment is perfect. Great tool to template hole that is needed to be drilled and taped for LSx iron block lower alternator configuration. The only thing that I would suggest to improve upon it is to weld a spacer to the hole that needs to be drilled as a guide to perfectly center the drill bit.
