GM 4.3 compatibility questions

[Xoloski]

Ayuh,... It'll work, but the 4.3l has Alotta Gotcha's....
Block # for Block #,... No problem....
Year to Year,.. The Nightmares can begin....

Are there some guidlines here?
do I need the same year chevy as I have penta?
what are the major differences between years? I would think that a range of chevy engine blocks would work with addition of the volvo heads / cam / timing gear & chain set / intake / water pump / fuel pump / oil pan.

I have a friend with a cracked block penta, I want to swap in a chevy 4.3.
Is there a blog dedicated to this process?
Thanks,

Ayuh,... There's alota tiny changes in the 4.3l over the years, 'n I know only a few of 'em,...
Google will find ya alota info on 'em...
If ya go with the Same vintage, you'll have less problems..

No reason to change the parts I hi-lighted... They're the same as a pickup motor...
