x out the stroker idea...
what kind of gains would i be looking at if i were to install better flowing mopar heads w/ 1.7ratio roller rockers, some headers, m1 intake, and a 52mm tb, i already have aftermarket exhaust. would replacing the cam be realistic?

 

Look at my sig and my jeep is fast. What you can do is just put a blower on there and you will have a ton of power. I would say get a cam that is around 500 lift and a either port your stock magnum heads or get a set of R/T heads. Then if you have an auto then a toque converter and a shift kit will help too.

5.2 V8 (Factory ratings 220hp@4400rpm/300lbft@3200rpm)

1. K&N FIPK: 13hp
2. Mopar ECU: 16hp
3. Kolak 3" catn'back exhaust: 13hp
4. Mike Leach headers/Y-pipe: 14hp
5. Autolite 3924 plugs: 3hp
6. Ported TB: 7hp/10lbft
7. Electric fan + ASP crank underdrive pulley: 8hp/9lbft
8. Speedtweaks IAT adjuster: 8hp

With the above mods, output should be about 295-300hp. Now the big stuff:

9. Mopar 2bbl MPI intake: 25hp/1lbft
10. Magnum R/T Stage 2 heads + CompCams 254HR-12 hydraulic roller camshaft + 1.7 roller rockers: 95hp
11. Vortech supercharger 89hp/65lbft over stock
12. 390ci stroker engine 215hp/190lbft over stock 5.2
13. Nitrous Express kit 50-150hp over stock


This is from Jeeps Unlimited and these number have been dyno tested so they are pretty right on the money.
