Which is easier???????????

Which is easier, changing the engine, blown 4.3 or changing a cab. Both are 89 reg cab standard, second has a 2.8. Thanks

Re: Which is easier???????????

I've helped with a frame swap before and that was an '85 cab to a '75 frame. There were only a few wires and such to move over (the truck just isn't what it used to be -- it's something.... different).

Anyway, changing the motor would mean basically making sure to put all the wires and plugs back into place. Not that difficult, mind you, but a lot of work.

Why one or the other?

<font face="Comic Sans MS">Basically the engine should be easier to swap out, especially if you plan to put one of the same type and fuel delivery system in it's place... I would think that to be easier than swapping out cabs, the computer, possibly wiring, and so forth... Plus this way you get the good cab with the 4.3L instead of a good cab and a 2.8L... The 4.3 is preferrable if you can manage it...</font>

Re: Which is easier???????????

Ok here is the deal. I have an 89 with the 2.8 drivetrain is EXCELLENT, however the cab mounts are rotted the rocker panels, the cab corners ect. can not be fixed..........now I can get a 89 with a blown/siezed 4.3, totally shot but with a near mint frame/body Both 5 speed reg cab. So put the 2.8 into the 4.3 truck or the 4.3 cab on the 2.8 truck???????????? Thanks

<font face="Comic Sans MS">In that event, if it's like that, it's difficult to say... The transmissions have different bolt patterns so they will need to be swapped out as well... I'm not sure about whether the crossmembers are the same, or any of that other good stuff... Perhaps you could see if a parts yard would like to trade a 4.3L in good condition for the 2.8L and transmission, or something like that... You can probably find some good low mileage ones if you look around, etc... Definitely the way I'd try to go, before swapping in the 2.8L... The 2.8 is not a bad little engine despite what some say, but if you have the option, you'd probably get better mileage and be happier with the 4.3L, just because you have to usually hit the throttle on the 2.8 pretty hard to get it to do what you want (at least I personally did, whereas the 4.3, you'd probably hardly ever have to boot it to accelerate well)...

Of course this is just an opinion...</font>
