........ Im not really interested in going into the engine,, just bolt ons that can be undone. Id like another 40-50 HP if possible. At least enough to take a GT500 easily. Since its close now that should put it over the top.
Now about those Roush Mustangs,,,
How about a Zex wet kit? All bolt on/in and at a 50# shot, should be very safe on the motor - if you run a slightly cooler plug (okay, 16 slightly cooler plugs).
That should give you the modest HP increase you want for around $1000.00.
