Default 347 Dyno Numbers

Just got an SCT chip and tune for my car, it is a 94GT with a N/A 347. I was hoping for better numbers but at the end here is where I am...
293.49hp @ 5300rpm and 333.49tq @ 4000rpm. Any thoughts, am I in the range or am I missing some horses? Thanks again!

Yes you are missing some horses. What heads are you using? I didn't see that in your signature....

Yea with a good h,c,i combo you would make a LOT more power.

Performer RPM with 2.02 valves, the cam is a Crane 2030, the clutch is in very good condition, about 20,000, just like the motor...

Wow you are missing about 100whp. My cammed/head 302 makes a lot more power than your 347. Are you SURE its a 347? Just have to ask... I'm building a 347 as we speak... It will be around the 380-400whp mark on pump gas.
I'm sorry to say, but those numbers are pretty disappointing :/
Let's figure out what's either missing or not working correctly.... What ignition are u running? What was ur timing set at?

Can you post the dyno slip including the air/fuel ratio throughout the run? Is the results from a dyno "tune" or just dynoing to check TQ/HP after your chip install? What cam are you running as I did not catch that? HP peaking at only 5300 it appears to be undercammed or something else choking the motor.

Not to sugarcoat things you do not have the right cam for a 347....

That a good cam for a 302.......

302 parts make 302 power......

Also i willing to bet your clutch is slipping

a KC will barely hold the power of a 302.....

Not being harsh or abusive just giving proven facts......

I am guessing thats 293 rwhp? so about 340 at the engine i would change the cam and what cc are your heads? you should be around 330 at the wheels with a 347 and those heads

Yes, I am sure it is a 347, I too was expecting around 380whp... I currently have an MSD 6al with a timing adjuster, set at 14deg. As for the shop I took it too, the owner seemed to think that 300-350 is pretty normal with my combo with 350 being generous?!?! I will definately look into it further as these are definately disappointing numbers...

I agree with you about the 302 parts, it just makes sense, I just wish I new that about the cam when I bought it... but as for the clutch I am 99.9% positive that it grabs, with no problems at that, I have had a clutch slip before on another car, definately no fun...

I can post the dyno slip tomorrow, but all it has is the hp, torque, mass air reading and air fuel ratio. All seemed fine, as for the cam, it has a Crane 2030. The guys at the shop seem to think that the heads are restricting flow to the motor. Thanks again!

Don't let the guy at the shop BS you.....

I built a 347 for a friend using those heads.....

and a custom cam & edlebrock rpm manifold

Granted the heads and intake had a little work done to them nothing major.....

that motor sent 430+ to the wheels......

some else to consider you are running relatively low compression on that motor......

I would def have a talk with that shop and if THEY were the ones who built your motor, discuss further options as to why they would think a 347 stroker would make less power IF not the Same power as a mild 302. Maybe it was their "custom" tune at a VERY conservative tune? I personally would be coming UNGLUED if I spent that amount of $ and get less power... If I can find my old dyno sheet from last summer, ill post it for you. I had a 302 with basic H/C/I with ignition and made 320whp on a 95 degree day in TX. There are a few guys in TX with the TrickFlow topend kit making 340whp.
PM me if you need help
