Mine Dyno'd 412/390 at the wheels and ran a 11.19 at the Track..by far I Dyno'd alot lower than the Engine has, but my curve looked more normal..well closer to what most people's have.

I would say if you want to call people out to learn how to build an Engine..a retard can take a wrench and assemble and Engine. It takes the brains and the skill to understand how everything works. Compare your HP to TQ numbers..something is definately off, I'm putting my money on the Dyno. If that part of it's messing up, you will get some interesting readings.

My first pull got me 404hp, like 17billion Torque. If I had that much it would of broke the Dyno and the shockwave of that explosion would've dropped every girls panties within a 5-mile radius.

Calm it down a little bro..

ok so tofay i took everyone advise and got on a dyno jet and i put down 367rwhp & 416.8rwtq so i still believe my dynos are accurate (only thing i did was fix exhaust leak) so the numbers are right. but i will keep you guys posted on my dyno after injectors and tune ALso my track video will be posted when i finnally go. and sorry if i came off as a dick on my last couple of posts but just trying to let everyone know im not lying. like i said it pulls harded than i even thought it would but it is what it is...

I would stop dynoing your car until you get the injectors/tune. You're going WAY lean on that dyno sheet in the high 5k range when you max the injectors.

Get a new dyno/tuner

Im running stock injectors on a LE2/GM-847 setup and its making power all the way to 6800 and not going lean.

I'm assuming you boosted the fuel pressure or something?

stock injectors are not going to work with that without some serious modification.

The only thing im running is a 255lph Pump. Ive seen plenty of people run stock injectors w/ heads/cam setup and have a flat air/fuel curve. Im not sayin it wouldnt hurt for a bigger set, and im not sayin there isnt a few ponies to be gained, all that im sayin is there is something wrong with this guys setup....I dont feel the numbers are true. That torque number is awful high for a stock cubic inch motor. And by changing injectors that he isnt going to gain 50 whp.

It all depends on the car/setup though and the condition things are in. If the injectors are old/worn out, etc they are not going to work as well. On my 94 car I did a scan and at high 5k rpms my stockers were at 90% dc at a near stock power level. If I had done heads and cam and left them untouched, they would have been way maxed out.

On the other hand some people find the stockers work up to 400rwhp or so, and that's generally considered to be their theoretical limit.

I agree he's not going to gain 50 hp by changing the injectors, and I already said there's no way he will get close to 400 with that cam anyway. But it's clear his car is not running right from that dyno sheet. Since he has stock injectors with no tuning, I'd be willing to bet that is the problem.

sorry, but there's just no way you are getting 400rwhp out of the 503 cam.

no one said your car couldn't be fast. You don't need huge dyno numbers to run well at the track. I'm sure everyone here knows that. I just don't think you are going to get 400rwhp, that's all.

If you can find some dyno graphs of other other N/A 350s making almost 420ft lbs at the wheels then maybe people will believe the numbers.

450 rwhp from a cc305. Sorry not gonna happen, not without some spray or a blower. It's just not there, even with the best heads and tune.

With some good ported heads and supporting tune, honestly I would feel like a lucky dog to get 410-415 with the cam that I have.
