1957plymouthhemi Several years ago I weighed some SBF parts on a 351W when I was trying to shave some weight the numbers will be close for a 302.

Edlebrock Aluminum heads saved 25 pounds per head (50 pounds)

Edelbrock aluminum intake saved 40 pounds (will probably be a little less for a 302. say 35 pounds)

Aluminum water pump 7 pounds

AFB instead of Holley 5 pounds

Headers and stock early style the headers actually weighed 4 pounds more although they were full legnth headers. Shorty headers would probably save a couple of pounds.

Yes I am. And yes your right however the only question I posted was about "How light can I get a SBF". Thats what I'm interested in.
I don't mind the thread taking a turn or two along the way. But all I'm really interested in is the SBF weight.

Thats what makes me think the SBF would be a good choice. I can think of other more interesting swaps but the SBF wins in being practical.

OneMoreTime going from 340 to 450 lbs is not that great a change but if you like aluminum heads and manifold along with some shorty headers will save some pounds. Using the aod is a good idea as you can get a complete package from a donor ford product and just go ahead with the swap..myself i would not loose any sleep over the weight difference as those cars handle well and are sturdy in their construction..

How light can a SBF get? w/iron block.

Still trying to figure out the best engine and trans to install in my 66 Volvo Amazon. If I start out with a fairly stock SBF its weighs 450 lbs.
(correct me if I'm wrong)
The stock 4 banger is around 340.
Wondering if anyone has seen a chart with aluminum heads, headers etc.
lowers the weight?
Since I'll be adding also an ATM (AOD) the lower the weight up front the better.
Just in the planning stages.
Thoughts welcome!
