Default Engine swapping.

Can anyone tell me if a V8 engine could be swapped with a n/a 3.8 from a 95 Bonne sle? Which is the biggest it can handle and such.

Just curious.

Straight answer, no.

If you are talking about putting a V-8 in our cars, in a FWD manner, you would go through way too many transmissions. Not even worth it.

If you are talking about putting a V-8 in our cars, in a RWD manner, this is where it is possible. However, we do NOT have a chassis on our cars. We have a Sub-frame in which the powertrain is all mounted to. There is also a little bit of strength in the back for the rear wheels. But other than that, all the regitity is placed on the body. And there is no way could have a RWD setup without a chassis. So, what does that entail? Well, it entails having a custom chassis built specifically to our cars. Modifying the body a little bit, to make it mount properly, and removing all of the old sub-frame whatnot. Then it would just be a matter of fitting the engine under the hood. I'm not sure about the 92+, but on my '89, I would certainly say it is a viable option to fit a small block V-8 in there. You can forget about a Big-block however.

This topic has been discussed before. Unless you have a whole heap of money, forget about it.

I'm sure he could tuck a caddy 4.5 or 4.9 pushrod V8 in there... The 4.9 was attached to the 4T60-E HD through 1994... Possibly 95... I forget what the last year was for the 4.9...

I think the C and H bodies are a lot alike.... I have heard of this being done...

But remember that the 4.9 made 200 Hp and 260 Ft lbs bone stock...

The 92-93 L67 or 3800 SC made 205 Hp and 265 Ft lbs

94-95 L67 was good for 225 hp and 275 Tq

96-03 L67 was good for 240 Hp and 280 Tq...<--- we have found this to be underrated

A few have done 260hp and 330tq

By the time you have dealt with all of this it may have been easier and cheaper to find a 96-98 SSEi Supercharged

Dropping in an Series II L67 would be easier, and you could prolly make just as much or more HP and TQ than any V8 you'd throw in there.

Bah, didn't think much was possible. I'll just convert it to RR and stick a V12 in the backseat/trunk

But, like I said, I was just curious. I'll probably end up getting that $3,000 turbocharger for power upgrade.

I just finished taking a 4.5 v8 out of my 1989 Caddy Deville. There is no way you could get that to fit, and still operate with factory reliabiity. It was enough of a pain to get it out of the Lac, I am not looking forward to putting the new one in. (1995 was the last year for the 4.9). I also looked into an early Aurora swap, also too much work. The L67 is the hands down choice.
