4.3L to 305 swap

I've been searching, but was wondering if this is possible. The donor vehicle is a 1989 TBI 305 V8 from a caprice. The frame is getting close to being shot and i'm afraid the body on the car is going to quit before the engine does. The recipient is a 1989 s10 blazer with a 4.3L V6. i dont have all the specifics on the engine yet and am currently trying to figure if it has a spun bearing (whole nother problem). If the engine is shot, i'm debating this swap. Let me kow what you guys think. Thanks for the help.

yeah man you can do it you just need some headers and some moun adatpers an the tranny will blot right up no prblem hummmm i have a 94 an i am leanin to put a corvett rad inplace of the stock just in case it starts to over heat with the a/c on but hey man it was a project for me take your time and its easy as pie......you can get a kit off ebay with the headers and mount adpters and a 4x4 oil pan for like 212 on lower

you won't need the vette radiator.If you have a brass and copper core, you can have it recored with a 3 row HEI core. If you have a plastic and aluminum radiator ,the heavy duty version will take care of your needs
