Edelbrock CNC lingenfelter Head EDL61969 Heads, What's the Story?

Does anyone know about these heads?

P/N EDL61969

I have recently been made aware of these heads from Edelbrock. I'd like to do a H/C in the future. They sound like a good product. I've already looked at the Edelbrock webpage. Their posted flow numbers look good. I have made enquiries on other forums. But there wasn't much feedback. Now I see that Lingenfelter has their heads as their own CNC'd heads. Flow numbers look good. But again there doesn't seem to be much discussion on the LS1 forums. I'm wondering if these heads are associated with Lingenfelter. Also, perhaps Edelbrock provides the castings and Lingenfelter does the CNC then the heads become a Lingenfelter product? What's the story?

Is anybody running these heads? Does someone have some feedback? Any tuner or speed shop feedback?

Thanks in advance.

Nah. I'd only use tried and true stuff.

Ported LS6 heads or a couple aftermarket heads like Dart 205cc/225cc or Trickflow 215cc heads.

As far as those Edelbrock heads go, they show that they are 202cc, which makes me wonder how much they were actually massaged. Stock is 200cc. I wouldn't do it.

Heads/Cam I'd do a set of ported LS6s from AI or Larry Meaux with a Futral F13 or F14 or for aftermarket (if money isn't an issue) the Trickflows (or Darts for less $$) with a Futral F13 or F14.

Thanks for the feedback. I live in Kalifornia, home of the Smog Nazis. So I like this product for it's CARB EO #. I know about AFRs (which are 205s) but my opinionated tuner does like AFR (I know :rolleyes:) But he knows his stuff in a land with a lot of knowledgible tuners.

I could go with some ported LS6 heads. But actually the smaller runners help with the low end torque. I am worried that the ported runners of an LS6 head will widen them and slow down the airflow. I need to do more research.

Again I appreciate your input. I haven't been getting much info about these heads.

If you're in Cali, then I'd definitely get some ported LS6 heads. Those are "factory" heads and won't bring up any issues during an inspection. Check out AI www.advancedinduction.com or Larry Meaux (I'd check out AI first.. Larry Meaux is much more race-oriented and you'll be waiting 6-10 months for a set of heads)

"Low-end torque" on an LS1? Haha. These motors are detuned race motors. Peak torque on a stock motor is over 4000 rpm. :D

Port size has little to do with low end torque. Even less so when talking about a 10-20cc runner difference.

Edelbrock has always made quality products. That's their trademark. Another one of their trademarks is that their product underperforms when comparing to others in the market. I am NOT a head porter by any means, but the raw castings I saw on the Edelbrock truck at an NHRA event years ago looked very poor. True, they were raw castings, but I've seen AFR raw castings too ;)
