the 4.3 bwllhousing IS the same as small blocks.
Its been done, there's been a few people come on this board running them. They all claim to love them and say they are powerful.
The only 4.3 I have ever driven that I would call powerfull was the CPI vortec... 92 - 95... i may be off on those years, but in that era. They had plenty of power... when they ran right. They were a nightmare though.
The rest of them, I never liked. I've logged 150,000 miles on a 2001 with a 4.3, and I still say the same as I have for many years. They are slow.
