It's really just bolt in and go, hed be losing power though unless that roots blower is making like 5psi.
and the rods in a 97 cobra motor are just as weak as his 2v motor, not worth the swap in that case imo.
Recommend finding a terminator setup to drop in.

+1 go with a terminator motor instead or get a built two valve and slap the blower back on.

I have an 04 Cobra short block built (brand new internals...bought from JohnB) and I have a pair of 04 Cobra heads complete with cames. All you need is head gaskets, oil pan and an intake.
I have an 01 Cobra upper/lower intake too...
PM me if intersted.
