His newest dyno is the blue lines if I read his post right. The blue lines were cut short for what reason?

so the heads would drop that much, i thought that was the whole point of having the heads ported, no not knocking lloyd at all and the work he does, but i'm just wondering why would make the eldelbrock heads even after porting flow so low?

idk call up eldelbrock and ask them why their intake they spent years developing looses HP over a non-ported stocker. I wonder what llyod has to say about their heads since he knows his ****. all I know is that eldelbrock is junk on LT1's(which my mustang fanatic machinist didn't like hearing )

I feel what you are saying but they are not just edelbrock heads anymore, they are ported LE2 heads which is a big difference. I'm awaiting on lloyds response as well i'm sure he can give me an answer, great guy to deal with. I know dyno's can be decieving but that's really low edelbrock heads or not, you can get 327rwhp from pretty much bolt ons from a LT1 i'm sure definetly from ported LE2 setup. We will just have to wait and see

A friend of mine said that it may be the fuel pressur regulator, any chance of that? I don't have an aftermarket one at all. Woulden't the tuner have seen that it's not getting enough fuel ?

We really need to see the A/F read out, It really shows more usefull info than the dyno graph. You may have an issue as simple as a clogged fuel filter choking your engine out. And I dony care what anyone here says there is no way you should be losing 140 ft lbs. of torque from 2.5k to 4.5k... A v-8 torque curve should be a plateau. The car in my sig has 375 ft lbs from 2k to 6.5k, with a peak of 392 @ 4300. Look into the fuel situation... Change the filter, and look into a good pump. -Chris

I'm sure they are better than they were out of the box, but they are still major junk in my opinion.

I dont have any experience with edelbrocks, but they are 170cc? Arent the stock heads 185cc? le2's are usually around 205cc, im not sure if lloyd opens the edelbrocks up that far. I think ported stockers would be the better option.

I agree with the grob, the o2's have nothing to do with your problem. And as a matter of fact, if there is anything wrong with the o2's, they will tell you for sure ( ses light )

yes but the smaller runners will hit their max flo long before larger ones, you have a larger cam than me, on smaller heads...... think about it. that being said, lloyd would have not set you up with that combo if it wasnt gunna work, I still think your problem is with the fuel system. G/L
