Damn, that is about the same combo I have and I am also hoping for 300 RWHP when I go to the dyno. Hope I'm not dissappointed. Have you gotten any times on the new heads yet??? I was running a 13.5 with the trickflows, stock TPI, and 2.73. Now I have the runners, base, plenum ported, and 3.42 and am also looking for 12s. Let us know how you come out at the track.

that does seem a little low. Are these 23lb injectors?

 

Hmm, seems really low to me too. I guess that's LTR TPI for ya though, several others are getting these kinds of numbers with the LTRs...

Since your HP is peaking so low, I would think that your torque is dropping sharply well before 5000 RPM. I'd guess that it might be a lack of airflow, the 190s may be a tad small for a 350 pumping out so much power, plus the Crane Cam may not have the duration it needs to produce power at the higher RPMs.

Just my guessing,

Jason

 

not bad, about what an LT1 with a couple of bolt on's puts out. but, problem i'm seeing is a cam barely any improvement over an LT1. with them heads, alot more can be had by putting much more cam in it. would be nice to see some numbers if you can get them though from the oxygen sensor under a wot pass. 300hp at the tires is very possible, but that is a rather small cam.

 

I don't think you would want to step up the cam much more at all unless you're going w/ a better, shorter runner intake setup. This engine is all low end w/ the long tube runner setup and a cam w/ a lot of duration isn't going to help there...

Hey guys, have you read the hard rock camaro articles in the article section of this site? It made over 330 hp to the wheels and it had long tube runners and the zz-9 cam. BadcamaroRS, even with your runners and cam you should be over 300 rwhp. I'd say your problem is with your fuel delivery to the engine, like maybe bad injectors or something, cause you should defineitely be making more power. That's just my opinion from what I've read on some of these car sites.

 

ive got 24# injectors id really like to see what i could get out of the ltr set up but if i knew the mini ram or super ram would take care of this i would get one im jus trying to get all the input before i drop anther $1000+ on the street i win races all the time thats what surprised me when i saw the #s i was running 13.5@104.66 last year with stock heads im bafled
