3800 Series I vs. Series II

[Flyby736]

Im sure you guys have heard this 1000 times but I cant find it in the forum so Ill just give it a shot. What are the differences between the 3800 Series I and Series II? L27 vs. L36 I want to know if any of the parts can be swapped from the Series II to a Series I....heads, intake manifold...Also does anybody know what it would take to put a Series I supercharger on a N/A Series I?

Thanks in advance

The block is completely different from the S1 to the S2. So bacially nothing will bolt up from one to another. S2 has a higher compression ratio also. 9:1 to 9.4:1.

 

As far as the S1 s/c swap, I want to do it once I get money. the blocks heads and crank are the same, except for the pistons, connecting rods, intake and the s/c. you would need the s/c, intake, the p/s pump and alt brackets. you will need a new harmonic balancer since there are 2 belts on the s/c motor. some tensioners off the s/c motor, and maybe a Memcal chip from the s/c computer.

 

BTW: It would be better to get the 94-95 s/c. better flow.

A friend of mine got a quote of 350 USD for a SI s/c installed. His friend may have been hooking him up or ripping him off with that.

 

Depending on your funds I would look into seeing about paying someone to do a L67 swap. Bigger aftermarket and more parts if something breaks.

The funds arent there for an L67, that was my first choice. Was it at a dealer or just a local shop?

Friend at a local shop.
