hp mods for 305
Re: hp mods for 305
Sounds like we aren't the ones that need to get our "hearsay" facts right Matt.
Be it the runners, or not, I may have that wrong, but I know it was from the intake manifolds design in whatever way. I coulda swore it had to do with the runners though.

^Indeed Jon; people on this board hear somthing weird and immediatly think you must be b/s'ing and it's so fricken annoying.
But I, as yourself, also thought that the problem was actually in the manifold itself. I *knew* it was intake-related though

Yea Matt, hate to burst your bubble, but every Camaro and Firebird from 82-02 that had a v8 used a chevy motor. The Firebird LG4 was identical to the Camaro LG4, as were all of the other V8 options.

I am very well aware of that

I just thought that *something* along the lines of the intake was different, causing some sort of obstruction.

I know it wasn't the actual intake, but was instead the plastic tubing. It's just kinda weird that just by screwing-up the plastic tubing, that much hp was lost

Re: hp mods for 305
You guys need to attend a car show or two and actually *look* at the under-hood differences!
As someone who has noodled with third-gens for going on fifteen years straight, I can tell you that for sure there is no difference in a TPI longblock engine, be it installed in a Pontiac or Chevrolet. However, Pontiac used their own electronic engine control and nduction system whereas Chevrolet used their own. They both used similar ECMs from AC Delco, but sometimes you'll find speed-density and electronic speedometers on the Pontiac whereas the Chevy still had mechanical speedometers and Mass Airflow sensors.
Chevrolet Camaros with their higher hoodline had a less restrictive ducting to the TPI whereas Pontiac put in a tube and routed it to a circular air cleaner assembly that was tucked up into the right corner of the fender. All horsepower differences were due to the induction plumbing and possibly the electronics and tuning. Whenever you talk aluminum or steel, however, the cars shared identical parts.

i do have to say that the only difference is the plastic that goes to the filter. man i need some of u guys to talk to a friend i have cause he has been tellin me that the firebird have more power than camaros so i told him that let me get my car put back together and then i will light him up, plus i am not puttin my car back together stock.
Re: hp mods for 305
[QUOTE=iansane]May I reiterate that "Ram Air" is a myth? The only benefit is fresh, cold air (which is an amazingly effective benefit).
well again, camaros get that fresh cold air from the plastic intake system it uses.

Re: hp mods for 305
Right, and you can do the same thing with the Firebird through the SLP cold-air induction kit that they sell. Or, you can get the rather cheaply made but effective solution at http://www.ramairhood.com and suck it straight off the front of your car. I must say though, when the idle air control circuit opens up, it sounds like the car grows a roots blower.
