Edelbrock heads and cam package for the LT1? Has anyone read this yet? See link below for install and dyno.

200cc heads? Maybe an alternative casting for porting?

 

Proof positive it is a sad little package. Not even the wonders of magazine lies can make it look acceptable.

 

all I need to see are Edelbrock, and LT1... and I know it can't be good.

 

did u read the sad flow #'s on the in take side . did not know those heads sucked that bad . exhausts seamed to look good

 

Its not a very impressive setup. In the article it states that the stock motor put out 249 hp at the wheels, with the Edelbrock setup it made 283. You can get a much better setup elsewhere for the same cost.

 

Your much better off with a set of ported stockers and a cam.. And it would be alot cheaper also.. :-/

 

IMO your better off getting a custom grind cam, and some dyno tuning. should run a hell of a lot better than that Edelbrock pakcage.

 

I'm not interested in purchasing this package. It may be a good option for someone considering an LT4 upgrade in a simple bolt in package that appears stock. I just thought I'd share the info with everyone. I am curious how the 200cc Edelbrock heads will work for porting. They may turn out to be a good alternative to the LT4 stock castings.

 

Bwahahahahahaha!!!!! wait, wait.........ahhahahahahah!!!!

Is this a joke? $2300 later and they're up 34 ponies after a head and cam swap. That is so incredibly pathetic.

 

You guys are failing to see the modifications made here. The heads are 170cc and are on par with the stock pieces. The cam is a 218/218 .525/.525 lift. They reused the stock rocker arms and all other stock hardware except timing set. So basically the only things this 94 Z28 have are a set of hooker 1 5/8" shorty headers with a 3" hi flow cat into a 3" Corsa for exhaust, SLP CAI, BBK 52mm TB, tiny *** cam, basically stock replacement heads, and no tuning or anything else! The car is making 283 at the wheels through a 2800 stalled auto. Not bad for basically the worst of all bolt ons for power. I bet with some long tubes, injectors, head work, and a tune they could pull 340 out of that little *** cam.

 

On top of the $2300 that was already spent for the package, porting, tuning, and misc items will add up fast close to if not over $3k. Sort of pointless when you have some guys running ported stockers along with a nice cam hitting over 400RWHP with a little under $2k. But yes like you said that might make a good little package by porting the heads, and getting the supporting parts.

 

I wish Edelbrock would have modeled the ports off their sbc vic heads.

 

You are the one missing the fact these are sold as performance and that a true bolton car(as in stock cam) can be expected to make similar numbers.
People talk like 1 5/8 is a bad thing granted long tubes would be better but for a motor like this 1 5/8" tubes are the right choice. I run 1 5/8" midlength round port headers and easily put another 100rwhp down thru a 3400 stall.

It is sad but there are going to be A LOT of guys with faith in a name and no amount of reality will shake it.
Edelbrock made good gen 1 parts with the LT1 though GM left a lot less room for as cast improvement and that is why they are struggling to make worthwhile parts. A decade ago they had the integrity to admit it when they admitted defeat on the LT1 intake the first time around .

 

Would be smart on their part to do so. There is just no real market for the LT1 anymore.

 

I will agree that there is more power to be had and that these are being portrayed as more than they are. I don't agree that the parts are subpar. The small intake port they have kept on these heads make them excellent for the numbers an independent test showed. Even at 28" that is a decent increase for unmolested stock castings. For that heads and cam combo I would have never even dreamed of a 52mm TB so that is added cost to the overall picture. They are using stock steel rocker arms and we all know the benefits of a full fulcrum roller rocker. There is hp left on the table in almost every aspect of this EXCEPT the heads. They perform to their level and I see much higher than stock casting numbers in these when ported. The castings say to have .300 more port wall. On the valves in these heads I could see 270cfm or more on a well known porters bench. These heads will require much less work as material around the gasket surfaces is already at its portable size. Bowl work and overall surface work is all they need to outflow a stock casting. These heads fully assembled require no machine work or new valves/springs. You buy these heads for 1000$ and put 500$ into some Lloyd Elliot port work and these will be cheaper than buying LT4 heads and trying to have them outfitted with all the needed work and parts.
