Dyno numbers?
I dynoed my standard Lt1 (93 mod) before the mods and it did about 250 rwhp (before any changes). The changes I`ve done are:
* comp cam 07-503-8 (Xtreme Energy series)
* new valve springs & retainers (matching springs to new cam)
* new Bosch design III injectors (from FIC) - 32 lb
* new tune from pcmforless.com
* Melrose longtube headers
* BB-tri flow 3" exhaust...
Just installed new chip today, and only did a short testride to check chip (so far so good)..
Anyone done a dyno with similar setup? Don´t know what to expect, but would like to see close to 300 rwhp...

don't know what cam specs are for yours, but a friend did a Hotcam, longtubes, tune on his Auto Z28 LT1 and hit 300rwhp, so I would think your would be at least this and probably more since you have a manual, and the cam is probably larger, & better exhaust.

Something isnt right.
Who adjusted your rockers? And did Alvin tune it for the injectors and Long Tubes?

Does that baseline seem low?
My 92 planted 278rwhp , only mods at the time were corsa catbacks and the SLP Triple claw intake............... through a auto ................ with 124k miles on the clock.

With a set of Borla Mufflers (not a full exhaust) , K&N and a chip I programmed, mine did what my sig says.

Before mods..
It's probably not clearly enough in first message (I'm not native english speaking guy).. the 250 rwhp was standard LT1 BEFORE any of listed mods.. I'm just interested to know if anybody has a dyno of his/her LT1 with similar mods, and what I should expect to see next time I will do another dyno run...
I hope to see 300+ rwhp...
