Opinions, are the Edelbrock FE heads worth the price for street motors or is doing a good port polish job on the stock heads enough? I got a set of tall port GTs out of a 69 now but no port work done, valve seats have been done. RV cam but thinking of doing a full roller conversion.

We got blue thunder , I donot like edelbrocks. I got a friend that runs blue thunder on his 64 and holds record in nhra. Paul Adams. He runs bt . I just listen when they talk as blue thunder is said will run better right out of the box that eldelbrock after you work on them for the money. I have never ran edelbrocks so I could not say. A good set of iron heads for half the money are scj 6090-N for the street. Add a tunnelwedge 2/4 intake and it will scream.

Thanks for the info. I'll have to check them out. Do you have recommendation on where/who to buy from???

Ive been told the edelbrocks are worth 20hp out of the box over any regular production head. Couple that with weight savings. Down the road they can be worked on. For something thats never going to be timed (track) BT's are overkill, IMHO.

I think you would need to run the matched Performer RPM cam to really see anything from them in a stock 390 configuration. I run a roller cam, lifters, rockers....so it's a little cheating. I am sure Blue Thunder rock, they were just a lot more money at the time.

Spent what I saved on other motor parts.

Whatever heads you run if you add alot of hp to a motor that the bottom end has not been beefed up you may loose the block. A good set of any kind of heads add alot of hp to a motor, my opinion the heads is where most power comes from. As stated below survival motor sports will have blue thunder but looking at their web side one cannot pin the price down. You can call the shop and talk to the owner Barry Robotnick and he will school you on heads if you wish to buy a set from him, gather up ya change before you call.
If I can help you donot mind asking .

Does the edelbrock efi intake fit with blue thunder heads? I like them cause the 86cc chamber will help me drop compression for a forced induction application.
Call Barry at Survival. He's an FE specialist... retired engineer from Federal Mogul, builds competitive engines for the Engine Masters competition, is a super nice guy, and I've never heard anyone say anything bad about him. I've dealt with him for small items, and never a problem.

Reviving my old post:

So I've decided to use a 428FE that I rebuilt a number of years ago for my currently project. It has zero miles on it. It currently has a rebuilt set of stock cast heads for the 67 year. I plan on using a MR dual quad intake I have and setting up a custom fuel injection setup already in the works. My questions are now where to spend some modest amount of money wisely. I already have new roller rockers and roller lifters that can be installed so a custom roller cam is a must. Would it be worth doing heads or perhaps one of the latest stroker kits to up the displacement? This will be in a 67 Cougar backed by a 4 speed, never raced and mostly just street driven. Doing both heads, cam, and stroker kit would be nice but I've got to spend a good chunk on body and paint and since it's a street car I wonder where the best money would be spent?

Opinions?

Going back to your original question, I pulled the 390 out of my 67, bored it .030 and installed a 428CJ crank and Mercury 410 pistons. I asked my engine builder what would be the best route to go for the top end and he suggested the Edelbrock Performer RPM heads and intake. I also got a matching cam and Holley 750 carb, Harland Sharpe roller rockers, hydraulic lifters, all new accessories, and an electronic ignition system. He said for the money I was spending it was the best combination of parts for a street car that wasn't going to see the track.

Unfortunately, I can't tell you how well it works because the motor isn't finished yet.

Big power is in the heads, however, with your intended use, if you get it breathing deep it'll be a high RPM motor, which doesn't sound like your intent

I'd build a nice mild stroker, it'll bring torque way up and if you ever decide to upgrade later a head swap is easier than doing the opposite.

There are not too many options, but if you shop around you can get some good deals. It'll be a couple grand in parts and balancing whatever you do, but you'll never regret it if the car is worth putting the money in.

FWIW, I run an EFI 489 cid FE based off a 427 block, and a carbed 445 FE based of a 390 that will eventually get EFI as well.

Additionally, generally you do not NEED a custom cam to run EFI, modern systems are not as fussy with overlap as the early OEM stuff, let us know here if you need any help choosing parts

Final comment, regarding your high port GT heads, those are very limiting without additional work and will be at least 50 hp behind a set of stock CJs or Edelbrocks. A C8AE-H can only support about 425 HP. They flow horribly and require a unique header for both bolt pattern and exhaust port location. Post your current head casting number before you spend a penny on a stroker. In addition to the ports and exhaust, the wrong FE head could make it so that you can't get the compression you want either (without custom pistons)
