Re: Crossfire mod.. plenum volume or enlarged TBIs first?

["Bruce Plecan" <nacelp@bright.net>]

Your now running the 747?.
What injectors?.
Ya, replumb the fuel pressure reg.s?.

You need to have the fuel up to snuff first.
If you overdo the air first then you can go lean, and start buying parts.

Did you cut the EGR tunnel out, and runner roofs back?.

| FYI, the car is an 82 Camaro with 350 crossfire, 450 lift 212 duration
cam,
| headers and high flow exhaust, 5 speed, 3.73 gears.
| Now with 7747 that I would like to start 101ing.
| The problem is, the car seems weak at WOT above 3-3.5k rpm, but my scanner
| and the dash mounted O2 show me between 800 and 900mv. The closest thing
| feeling wise to describe driving the car is a mid to late 70s camaro or
| monte carlo with 350 2bl. Feels strong less than 1/2 throttle, but doesn't
| feel any stronger at WOT than 1/2.
| Would a lid spacer to increase plenum volume and the stock TBIs help
| overcome this, or should I enlarge the TBIs?
| Would just enlarging the TBIs help without adding the spacer at the same
| time?
