How much weight is saved with aluminum heads?

Could somebody please refresh my memory, what is the total weight savings with the running of aluminum heads, all other things being equal?

Folks are going through lots of bucks to try to get good power out the the 4.6 modular engines in the Thunderbird and I'm wondering why I couldn't drop a bullet proof big block in there with as much aluminum as I can get on it to save weight? They did come equipped with a 5.0 so that would make more sense to build, I guess. The big block just makes so much torque and it runs effortlessly while making big power, those smaller engines always sound like they're about to blow up. That freaking 89 Tbird I bought the wife is a great handling car, I wouldn't want to ruin that with too much weight, though. I suppose I could use that same pricipal and run aluminum heads and intake on the 302 and build a light weight small block to suit the car better. Any strong opinions on the subject? Thanks, Roy

4.6 weighs to much itself. I read an Edelbrock add once that claimed 70 pounds difference in their heads vs. the cast iron.

I weighed my Kaase SCJ's when I did my rebuild. They were 60# lighter than the iron heads, on the bathroom scale I used. I don't remember all the specific weights, but do remember Heads, Aluminum Intake, & Aluminum Water Pump took off 100# from the iron parts. But I do think my aluminum fined valve covers were WAY heavier than stock.

Never seen a 4.6L with cast iron heads... I assume you intended to say BBF since Edelbrock does not make a head for the 4.6L ?

Do you know how much a 4.6L ford weighs, since you feel it is too much ?

I think what I stated was simple enough to figure out, especially for one such as yourself :roll:

I was stating a 4.6 weighs to much to consider it over a 460, it is not that much lighter esp a 460 with aluminum heads. I don't know overall weight, I do know block is 154 (iron) and heads are 44each. So A bbf block is like 220 and the aluminum heads about 40each. So what is the crank weight of the 4.6 I don't know, or the extra weight of the cams. Considering the size I imagine the intake weight is similar. The fact is that sbf and mod's are not as much lighter as people think. Even a 2.3L is not as much lighter as most think. Are you going to enlighten us all again?:roll:

I was stating the Edelbrock 460 heads are 70lbs less a pair.

No, you can stay unenlightened :roll:

I just hope others here will do some independent research before accepting your statement that the 4.6L is too heavy.

Most anybody here who reads my posts knows I only like 4 bangers/6 bangers/ and big blocks. So no matter what a small block or modular is just a door stop to me. Don't believe me? Come over to the garage and look what my doorstop is.

I see no reason to ever use a 4.6 unless it is already in there.

500 hp 4.6L's are pretty common nowadays. 600-750+hp doesn't take much more effort. They're nothing to sneeze at.

I have seen 750hp supercharged 4.6L's and they don't last long at all, not the ones I have seen (and built by a pro 4.6 builder), that is with forged cranks, steel rods, and aftermarket blocks. I kind of figure for that money I would want something to last, esp. with $200 an hour tunning cost. Fast yes, something to sneeze at yes. It is no different then the rice burner engines; fast today gone tomorrow. But it is pointless to fight over.

670lbs? The BBF is a bit lighter than that I think? Seems like it would have to be since the listed weight of a stock iron headed 460 is 720lbs.
