[Kingakeem17]

I have a 98 mark lsc what do I need to make the cobra heads to work?

What year?

Your existing "B" heads for the most part are the same with the exception of the intake cam.

Later "C" heads would require the matching intake, not sure if anything else is required.

96-98 cobras got the same B-heads as our Marks, and 99-04 cobras have newer C-heads...

So, for 96-98 cobra heads, nothing...and for 99-04 cobras, bunch of **** if I can remember so its better to drop a complete 03-04 cobra motor in

I thought it was the exhaust cam that was different

How did you get a j mod and stall corverter

Get?

You need to do some specific drilling of the separator plate in the transmission for the J mod. Do a search, everything to know is there.

To change the stall would require buying a new torque convertor with the stall of your choice.
