The Chevy small block engine is iconic and especially exciting with the LT 1 refinements. It is clear that GM has gone all out to produce a very special engine. I am delighted to own an LT 1 (Z51) because of the outstanding performance and it appears that the government will make it obsolete in the not too distant future,.... then it will most certainly become an all time collectors item. For me, too, a special connection to the past; my first car was a new 1956 Chevy Bel Air, small block V8 with power pack. What a car!
