new motor swap dyno numbers :)
ok so i installed my motor.. and had it running on a driveability tune from john millican... i got a pretty good numbers.... 277.7@5800 rpm and 303.3 torque @ 2800..... again this is on a drive ability tune...
hehe and it was running about 13 to 1 on a/f....
mods
355
trickflow 23 degree heads with 1.5 roller rockers
comp cams magnum 292 cam, .501 lift, .244 duration on a 110 lsa...
stock lt1 intake with a bbk 58mm throttle body with 24 lbs injectors...
hooker 2055's and a 4 inch mufflex cat back...
with a good tune it should be well over 300
hehe
i need to see if i cant scan the dyno sheet

That is one huge cam for a 355 cubic inch motor. 244 degrees on the intake side!!! 13:1 should be pretty close on the A/F ratio. By the way with a cam that big your peak horsepower should be well into the 6000rpm range if not higher.
I would love to see the dyno graph. I assume this is with a manual transmission. If an auto I would assume a high stall. Allen

Above 5000rpm you are leaning out big time. More power to be had there and possible motor safety issue the way it is leaning out.

yea i think it might be in the chip.... will have it tuned here within a week or 2.... heck might even be the fact that i am running the stock lt1 fuel pressure regulator..... hehe and or mabye a fuel pump falling short... who knows but it sure did sound MEAN and scott settelmier-fbodyfather (SP) was impressed
hehe
