Who wants to see the dyno of an LB9?
Is it sacreligious to reference a gen I on an LS/LT site? Hope not.
Had a dyno day this weekend with some portland guys and put my '91 up on the rollers. Not too much done to it. Aftermarket manifold and an lt1 cam. Even the exhaust logs are stock. Same with the tune and as you can see at the bottom, the wideband is pegged out. I'm running pig rich most of the rpm band but I suck at tuning so that may stay that way for awhile.
224hp and 247ft/lbs

Amorget, what all did you have done to yours? Stock? There was another guy with another 305 that had TBI, intake manifold, headers, port work on the heads and just a slightly bigger cam that dyno'd 223/258 so I'm sure there's a bit more in there.

The lb9 and L98 is the first of the multi port fuel injected (TPI) fbods. The lb9 is the 5.0 boat anchor and the L98 is the standard 350.
Stock rating is I think 210 or 190 at the flywheel so I was impressed.
This is through a t56 so I don't know which would eat more power, I assume your 700r.
Wait...turbo? Whaaaaat?

FWIW, the 350's were 245 for 91.

I am still on the hunt (not very actively lately) for a 1991 or 92 Z-28. I miss my old 3rd Gens and with all the stuff you can do/available for them now, it would be sooooooo
