Lets play: Name that Dyno!
Lets see who can determine what you think the final hp/tq numbers would be given a specific engine/exhaust set-up:
Stock (per Mfg.) HP= 190 TQ = 240
Situation #1
Type of engine = L69
Engine/carb/intake/heads= Stock
Spark plugs/rotors/wires= changed in last 12 months
Headers =Hooker 2055 headers
Exhaust = Magnaflow 49 state cat converter and cat back. 3 inch pipes.
New hp #_____
New Tq #_____
Situation #2
Same as above but with ported 1.94/1.5 416 heads

Re: Lets play: Name that Dyno!
Stick it on a dyno and find out. I doubt the stock rating won't even match the dyno results.
Always is.

Re: Lets play: Name that Dyno!
It also depends on the brand of dyno.

Yes, theoretical or based on someone else's experience. Also trying to have fun with this at the same time...
It seems that these possible mods to the 305 run into a variety of hypothetical conclusions. I just want to see if anybody has first hand experience with these situations and can provide some data so there can be some expectation as to what to be expected.
