I have an 88 iroc 305 with the 5-speed, and I was wondering where i should shift at, and what RPM's I should cruise at.

92 Firebird: L03 305 TBI, 700r4 auto
Idles at 600rpm
45mph: 1100 rpm
55mph: 1300 rpm
65mph: 1500 rpm
1st-2nd shift point: 3000rpm (normal?)
2nd-3rd shift point: 4250rpm
3rd-4th shift point: 4000rpm

All engines differ but my L69 likes it between 15000-27000 rpms.

Hey theres that blond again. Stop doing that to us.

He's got a manual, and you posted auto tranny information.

If you're trying to accelerate very fast, shift when you feel the engine isn't making any more power.

Cruise in 5th gear, unless you have to go 10 miles an hour, but that's not really cruising.

it will also depend on ur rear end. so maybe people should post that too

ummm.. shift when you reach the end of the power band.. that way, when you hit the next gear you'll be at the beginning of the power band, going up to the end again, and shift again, etc etc etc.. make sense? you should be able to feel it.. you don't need stats and numbers to tell you this.
