You're starting a project where a tremendous amount of the original driveline will be entirely unsuitable.
You're going to scrap everything from the radiator to the rear axle, plus the front springs. And that doesn't include repairs due to wear or negligence, like ball joints, idler arm, control arm bushings, rag joint, and so forth.
Re-think this project on a GMT400 that already has a big-block in it.
This is not helpful. So what if those components need changed...have you priced out what clapped out 454SS pickups are going for these days? Wear parts need replaced regardless of V6 or 454 starting platform, they should be addressed on a regular maintenance schedule. So that is a moot point.
Your negativity is just that, sometimes its okay to just not post your opinion.
OP:
1. What years of the GMT400 platform was a BBC offered and what Gen were they? All of them
2. Is it safe to assume a Gen IV BBC will bolt in on any 88-98 chassis with the proper factory motor mount frame perches (say from the early 90’s – 454SS truck, I’m assuming the bolt locations specifically the motor mounts and Bell housing location and pattern is the same between BBC generations – please correct me if I’m wrong) Yes(Yes)
3. Do the frame perches even have to be changed from the V6 version? I personally cannot answer this, but believe the 4.3L frame side mounts are similar if not the same.
4. Are headers readily available for this combo? Yes
