Weight of Engine I6 vs V8

I am hoping someone out there knows what the mass of a V8 and an I6 long motor is. I.E., How much heavier is the V8?

cheers....

Hmm 50kg more with V8 packing aluminium heads? Sounds a bit high.

Have a look at the specs Ford lists for the current Fairlane Ghia.

http://www.ford.com.au/showroom/pass...Fact_Sheet.asp

Difference is 16kg in favour of the I6.

Factors to consider here. I6 used here is VCT version so maybe regular I6 is lighter? V8 used has iron heads. Deduct 20-25kg if aluminium heads are used. Manual comparison may work out more favourably for I6 what with possible difference in weight of flywheel, clutch and transmission.

5 pounds? That all? Is that because you've got a more compact block with a V arrangement? Maybe I should be looking at a getting a 302 instead of doing up the 250.

Re: Weight of Engine I6 vs V8

im pretty sure its because the i6 was not designed as a performance motor and was put together to last, were the windsor 302 had a lot of designing befor putting together and they were just able to chop alot of weight out of it
when you take a 302 apart everything is small compared to a 250 conrods are much thinner,
the trick to hi revs is less weight and they found a strong and light way to do it with the windsor
good motors
