Block ?

[Sinister80mc]

ok I'm in the process of gathering parts for a project car it is a 1980 monte with the 3.8 carb turbo set up. I will be going sfi Ic turbo with it my question is what is interchangable ? Can I use the current block with later heads
I have searched and haven't found any clear answers. Thanks in advance for any help.

I guess you could use the complete shortblock and put the later heads on.

Keep in mind somewhere in that time frame they swiched the threads i think to metric, so I'm not sure what parts will work together.

I don't think that block will have the knock senser provision.

drill and tap the oil return line on your block just like the 109 block has the return line.....ive done it before and it works!!!!!!! :biggrin:

Or you can run a return to the oil pan. This works too if you don't want to drill the block.

I would think you could use the whole running short block.
