1990 Silverado Deciding what Engine to Swap
Well here goes my first post if I mess up on anything just let me know. Anywho, I've got my 1990 Silverado with a 5.7 350, I'm not the biggest expert on these things so forgive my noobness, what are my options? Can I go 454? And if I can how do I know what 454 to put? Or if I decide to put something else what fits? For example can I just throw any 5.7 350 from a suburban, Tahoe, corvette, etc. Once again sorry for the noobness and thanks in advance

I would just build the 350 up, rather than going to a big block. Any TBI 350 should swap right in, from 88-94. With a Vette 350 may have to swap the intake manifold, but I'm not sure on that. You can throw a Vortec 350 in, but you have to buy a new intake manifold for it to run the TBI. I
