here are my mods...(350 LT1)
Ported heads the flow 255cfm on the intake, 194cfm exhaust. CC 305 cam, electric water pump, hooker long tubes, Ram air, borla exhaust, 1.6 rr's, comp R lifters...etc etc. You guys get the idea.

The numbers: 335rwhp, 310rwtq up to 5900rpm with an average air-fuel ratio of 12.7.

Are these normal numbers? What could be wrong? Are my heads crap? (I heard talk of the short turn radius being messed up) Why am I making such low torque numbers?

The car has been tunned (off the dyno) to run pretty well using LT1 edit, and the car ran 13.9 @ 103mph with just a borla catback, K&N and hypertech if that gives you anymore insight.

Thanks, I'm pretty dissapointed for the kind of money I have invested...I hoped for at least 350rwhp and tq.

Hey Andy,

My question is do you have any logs or can you get some?

But i will also move this to LT1 as this doesnt fit the Adv Tech forum. Thanks.

 

What kind of dyno was it run on? A Dynojet, or a Mustang? A Mustang dyno will read lower because it puts a load on the engine.

But, your numbers sound about right for a CC305 with a mid-level port job. Torque is a little low, but not ridiculously so.

Go and run at the track. Your MPH will tell you more about the power you're making than a dyno can.
