An iron FE block weighs from 195-210 lbs and an aluminum Pond FE block weighs 120-125 for a weight saving of aprox 75 lbs ---also Edelbrock heads will save 50 lbs over iron Ford heads--------

An iron 351 w is near 575 and a Dart iron block/alum heads at 465-470-

I guess that my point is that everybody wants to talk weight differance but has no idea where or how the differance is-----I've weighed everything in an engine including the nuts and washers, narrowed studs, amounts of coolant/oil system capacity makes, weight of hoses/fittings for remote coolers/filters(Ihave run race engines without oil filters to save weight of filters and oil in them)

Usually the mounting location of components(including engine /trans location) in both for/back AND height can/will effect handling/traction more than just basic weight differances--------

Anyway--sorry to hijack a thread about w or modular

You typed a lot of words but you failed to ever address the weight. If you have this much information on weights, why not share them? Why make your message so cryptic? We can find bare block weights everywhere, that isn't hard to do. And we can find 351w crate engine weights everywhere, again, not hard to do. Head and intake weights? Yep, still not hard to do. Why compare a bare block to a crate engine/long block?

In your experience, how much more does a similarly equipped 351w weigh compared to the 390 FE? How about the 460? You came in here to ask the question of weight difference when you could have apparently come out and said it from the start. So go ahead...just get to it and post the weights. If you have the information you could have stated in your first reply to this thread and this discussion could have easily been wrapped up.

Not sure if this will clarify anything but this chart on engine weights is pretty interesting. I pasted part of it below. Looks like an iron FE is about 125 lbs more than an iron 351W.
