| i got a 89 iroc. 305 tpi. i currently have a hedmen headers, accel 8.8mm wires, hypertech chip (stage 2), open box, free mods, accel coils, flowmaster exhaust, tornado, air fowl with stock throttle body, b&m shifter, monster tach, posi, stock gears, modified mass air flow sensor. i was running 15's in hawaii. i was told that with these mods it suppose to be quicker. so what do you guys think with these mods? should i be in the 14's since we adjusted my cars timing. it was on 28 degrease. it was real off. so we adjusted it to 7 degrease. should my time be better now? |

Car: '85 Z28 Engine: 305 Transmission: WC T5, 3.23 posi | Is that 28 degrees base timing? If so that would cause some power loss. Base timing should be about what you set it at, on a stock motor. More modified motors may need more base timing though... |

Car: Check The Sig | tornado... gone
hypercrap chip... gone
timing... go to 10*.. thats about as far as that hypercrap is taking you... cant go much farther then that with out the ecu correcting you and setting it back. I need to find someone with an advanced timing light so i can start playing around.

Still working on what I want to do for the tip(s).
I used to have the 2.5" pipe w/out the cat and a crossflow
flowmaster, but my motor didn't like the restrictiveness of the
flowmaster. The car run's 100 times better now running just
the cat and no muffler... not to mention it sounds great!  |

Car: 4 Mopars total Engine: Pentastar power Transmission: T/F and New Process Axle/Gears: Three 8 3/4's & one 9 1/4 | Mike...just to let you know, it wasnt the Flowmaster that was restrictive on your car, it was the kinked up stock 2 1/4" pipe you were running. Of course its gonna run better with 3" all the way out. By the way...you gotta hear your old muffler on my 84. Sounds great. Might have woke it up a little bit too. See ya at the Pavs.

Joe | Joe... Just to let you know, I wasn't running 2 1/4" pipe. I had
2 1/2" piping throughout the entire set up. Besides, running
the 3" cat with the new piping sounds a lot better than that
cross flowmaster. *L* Too bad there's no room for a 40 series.
I'm glad you like my old muffler... I might be getting a dynomax
bullet put on...or I'm going to finish off the tip(s).

Hell, the stock exhaust on my 84 is choking it. And my L69 exhaust is a lot better than your old LG4 exhaust. What I wouldnt give to have my old Edelbrock headers and SLP catback back in my possesion. Im glad youre happy with your new exhaust, but if I were you, id be putting a muffler on that thing. BTW, you sure youre gonna use those headers? Ill be more than happy to take them off your hands. Gimme a call. Later man.

heres another view | thats kinda neat, but why wouldn't you just build a double hump cross member to do that instead of cutting up your frame rails?

First he has the spohn crossmember and torque arm. You have it easy because you have the lift bars. Also, he has an auto, and there isnt really much room to run the exhaust beside the auto's or make a double hump crossmember. I just swapped to a t-56 and had a custom crossmember made to clear my duals and it worked out pretty good, but I dont think it would have done any good with the auto.
