I want to replace the tired 350 and TH350 in my 72 SS El Camino but undecided on whether to go with a salvage takeout later model 5.3 LS or buy a new 350 or 383 crate with EFI and OD transmission. It seems like the latter is much cheaper and mostly a bolt in swap. Either way I’ll replace the radiator and maybe swap the fuel tank for the EFI. Any suggestions and/or past experience with a similar situation would be much appreciated. I’m also looking at updating my suspension with Speedtech parts since I live in Southern Utah and they’re close by. My intent is to make the car my daily driver when I retire next March and I want something reliable and easy to drive and maintain.
