Not Shoe, but experience with Performers |

I wouldnt waste the gasket. Its certainly lighter, which is good, but I havent seen one FE run better with one. No worse, but no better. Matter of fact the difference between a CJ iron, or a PI alum and the Performer is so dramatic, you'd never run one if you did a before/after swap.
If you cut the plenum back, add a spacer, and do some port work they are OK, but for the cost of an RPM, F427, or PI you'll make more mid range AND believe it or not more torque.
Bottom line, they were designed in the times of the gas crucnhes and never worked so well, their RPM rating kept sales good for the low end crowd, but the RPM is a much better deal. Remember their competition was an SP2P, a manifold only good to about 4500 rpm, the Performer 390 may be OK on a 352 or 360, but dont expect much. As far as stock vs Performer, I'd probably run it if I knew I couldnt afford anything else, mostly for looks, but again ont expect much |
