How did you like the tfs1 and GT40’s?
it did its job well, and was reliable. was a low-buck, basic, get it back on the street deal (with the explorer bottom end). made 275rwhp/300rwtq in the heat, ran mid 13's on street tires, never ran hot, other than oil filter o-ring getting stuck and "doubling up" after i painted the block, i never had a mechanical problem out of it in around 4-5 years. just upgraded to some tfs heads that i already had from before after getting my fast daily.
