i have a 1967 283 with "327" camel back heads "they might be 283 power pack heads, i need to check my SN#"... i want to put the 283 back to the TBI that my 1989 silverado had to begin with.. is this possible???

 

i think the power pack head's had just at pointer in the middle of the square pad, instead of the double hump in pad on the later 60's head's .

 

Not for nothin' but Corvettes had Fuel Injection back in the '50s...

They're both an "L" block, right? Why not? See how the gaskets line up, for one. Worst come to worst, you might have to use the 89 heads so the TBI lines up.

 

its got the double humps.... and will 350 heads fit that small of a bore 283cid??? i heard that theres a spacer that makes it go from the 89 tbi and let it bolt to the 4 barrol intake... does that make sence?
