big block conversion ????????????

[tbear99]

This question is how i found this site.I have an 88 blazer love the blazer but while i was otr driver the body roted from sitting.I bought a military 85 blazer with bad motor and basically a parts truck with a good body and frame interior already stripped out which is actually better for me being i want to use my interior and wiring harness from 88.The plan is lift body off and and basically build from frame up.well my little 350 while pushing decent ponies I was thinking of putting a big block in it.I can get a 91 454 SS pickup with about 140k for about 600 in spring.I was thinking i could leave tbi unit to help with fuel economy.What are some of the problems i might run into with the 454?? my dream would be to have a 427 or 396 but thinking i won't find one of them reasonable enough for me to afford.
