Thanks guys. Kinda want to go with a stock block and head castings. this way if things blow up replacements are fairly easy to find. Ive been building turbo ford 2.3 4 cyl for about 15 years now so I have some experience in turbo engines. I happened upon these cool little gm engines when I bought my 71 cj5, which happened to have the 153 in it https://www.inliners.org/ubbthreads/ubbthreads.php?ubb=showflat&Number=81323&Main=9759#Post81323
Really like the fairly stout construction, high rocker ratio, and the heads flow fairly well for what they are, The best is the v8 style bellhousing pattern!!!
