Edelbrock Heads (Lingenfelter) ?????
In the July 2006 issue of GM High-Tech Performance, page 20.
These new heads have a cc of 65 and are ported (ofcourse).
Valves are 2.02 intake and 1.57 exhaust.
Intake runners are 202cc intake and 83cc exhaust.
Heads flow 300.5 at 600-inch lift and exhaust flow of 216.9 cfm.
Car is stock has lid,filter and Magnaflow exhaust. (STOCK CAM)
My question is how do these heads get 52 more hp ? Is it just porting and bigger valves ? 65cc is the same as ls1 head cc.
If I ported my LS1 heads (241) the same and put the same size valves in, would I get 52 more hp ?

I wonder if the port design is a little different. I haven't seen them in person, and I hadn't read that issue of GM HT perf, but do the combustion chambers look the same? Are the bowls the same? I could see with those kind of numbers @ 600 lift. Should run pretty good... Not sure 52 hp but it could.

Just put a set on my car, they are an extremely nice piece, the cnc work is unbelievable... I didnt get a chance to dyno yet, just put a tune in it to make it idle so i could move it around.. put in a cam to so we'll see what kind of numbers it makes

the heads are really nice and they do flow those numbers we had them independantly flowed when we did the install, they are a high quality piece, just that Edelbrock was late getting to the market , they did alot of resarch and testing before they released the heads to the public

It has two BIG names and I'm sure that it will live up to the Legend that is with those names. Every body was hot on them until the Darts showed up and then everybody stopped talking about them and then reverted to the old standby AFR's. I think everybody is in trouble now that the big bore motors are hitting the streets. We are gonna want bigger valves 'cause we can. Also the L92 heads flow like hell and are cheap as ****. Once the aussie manifold comes available and some of the porters work there magic it'll be a whole new world for us. Also the LS7 heads are in the mix too.

i worked with Tim on the head install, and they where a very very nice head, i run afr's on my car, however if the Edlbroke where out when i bought heads, i would have bought them in a second over the afr's

Why do you prefer the Edelbrok heads over the AFR?

if there a improvement over the stockers like the edelbrock heads on my gen 1 small block (etec220's) then id say these heads would deffinitly be top notch desing and power increase. the heads on my gen 1 gave more hp then any other 2 mods i did to that car.i didnt go big on the cam at all though.

Thats dam good!!
Does he still have stock cam ? I'm really liking these heads.
Off the top of my head, I don't think I have ever seen a set of heads with the same compression ratio like the Edelbrock give 54 hp.(GM high tech performance)
