So how much would this proceure cost (engine, new gaskets if necessary, fluids, special reqiured tools that a normal toolset wouldn't have). I am doing an engine install in my Caddy soon so I will get the basic experience from that, but is this something I could do in my driveway with a few expensive tools or do I need to drop the engine instead of lift it out? I can take it to the school shop, but how long would it take to get all the necessary parts out, take the engine out, and put the new engine in and pull out?

You do it, and I'll volunteer bring car and motor and you got a deal Hmmm... I'll purchase a motor, you come to me, and I'll volunteer my car... if only I were in Ohio... That, and I have the 3.5L, I doubt that's a drop-in

When I had the engine replaced in mine, everyone said theres some kind of difference in the wiring harness. Is this true and if so, how did you overcome it?

Is this true and if so, how did you overcome it? depending upon the year of your classic you will have to swap the knock sensors between motors. in 95 the knock sensor is above the transmission, and 96 and above the knock sensor is under the intake manifold. but the old knock sensor hole remains on all 96-99 4.6 blocks, its just plugged. you remove the pulg and insert your knock sensor. if you have a 95 you will also have to swap your intake manifold onto any year 4.6 95-99. there are no wiring differneces between the two engines, as they truly are the same engine barring the displacement difference.

The 3.5L uses a 4T65-E. again you will be surpised what a simple engine harness swap will do. combined with a pcm change, and maybe a new cradle and mounts idont see much difficulty. trannies for these cars are fairly cheap do to GM's cookie cutter powertain usage. the high feature 3.5 is more expensive to replace than a 00-07 northstar, due to the 3.5's very limited usage. not to mention lack of manufacture.

What stops the 4T65-E from being used with a V8?

What stops the 4T65-E from being used with a V8? On our 5th 4T65-HD in the GTP 3.8L SC. The 4t80 is a brute compared to the 4T65

What stops the 4T65-E from being used with a V8? It's currently being used in every FWD car that GM produces with a 5.3 V8. The newer ones are obviously better than the older ones.

The newer ones are obviously better than the older ones. huh? are you serious, they have used a lighter transmission on a v8. maybe they make extreme use of torque management, i heard they overused it on the newer GTP's. to make up for lighter transmission usage. do you have any insight into that.

I ve already heard of problems on the GP forum with the LS-4 using this tranny. Yes torque management has taken on a life of its own. As with the older GTP the trans was the limiting factor in how much boost and torque the package would handle. Just a pulley upgrade alone is enough to kill the tranny. Intense can build a 465 to handle about anything you throw at it for about $3K.

This is great info, thanks for sharing. I do have a question regarding different year swaps. I was under the impression that an OBDI car i.e. my 95 would not be compatible with an OBDII car. something about the crank trigger having a different configuration. Is that incorrect? can a 95 OBDI be swapped with a 99 with no PCM issues?

what I would like to know is what is the actual difference between the bore inserts between the 4.0 and the 4.6? Is the wall thickness of the inserts the same but that the bore diameter is smaller on the 4.0?
Or do they use the same sleeve and just bore the sleeve larger for the 4.6. If that was the case, then a rebuild from a 4.0 to a 4.6 would achievable.
has anyone ever investigated this?
