[93blackthunder]

Getting new one but have a ?. Will 95 tbi heads work on my 93 4.3 since there tbi too? That would be awesome.

They will work as long as there not a 96 up heads

Get heads off of a 1994/1995 Fullsize truck, they are gonna be CPI heads, bolt right up and add about 10HP over the TBI heads.

CPI Motors were only on S trucks

Gm used CPI HEADS on the 1994/1995 Fullsizes, they bolt right upto a TBI intake, easily identified by the raised "eyebrow" of the intake port.

[93blackthunder]

Lol can't afford v8 swap yet but am planning it. Why just 10 hp if 93 was rated at 165 and 95 was rated at 200

1994/1995 Fullsizes never used CPI heads and CPI Heads were exclusive to CPI motors but if you do find some CPI heads they will work

Honestly man, I'd go with a 350 at this point there all over the place just go to any junkyard or on craigslist.
