It looks like we here in Texas are about to get something akin to CARB regulation. So, in planning for all I want to do to the '73, I'm trying to decide on what to do engine wise. I am good, healthy engine wise, but not so good from an HP standpoint. I planned to build a 425 hp 383 stroker, which I already have a brand new 4 bolt main block and 400 crank waiting for. However, with the new regulations going into effect I am starting to think I need to consider just building or dropping in a later model Vette (or similar) engine, complete with electronics and cat's. I would like to get some opinions on this. I know that I am looking at a much larger expense to go later model. I also am not too keen on having to put all the electronics in, as I am not good at that type of tuning (not that I'm all that good on any type of tuning, but I at least fool myself into thinking I am). If I go this route, I might be pursuaded to do something exotic (no I'm not talking about dancing, unless it gets me a better deal on an engine). Anyone ever tried to squeeze in a Viper V10 in a C3 Vette? OK, maybe not that exotic. I could use some opinions here. What ever I do, I want it to be quick, last until I die, and pass emissions. Wha-da-ya think?
