Small Block to Big Bolck Comparison

[Mikecolosprings]

Anybody know the weights of Empty 5.0L ford Small Block and the 7.5L ford Big Block

I am not sure what you mean by empty weights! An average 302 weighs @460 lbs. and an average 460 weighs @720 lbs. Of course aluminum heads, intakes, oil pans, etc. etc. will alter the final weight of the engine. Hope this helps.

By Empty I mean Block only.

[NASACastang]

A stock 302 weighs @ 150lbs "empty" and a 460 weighs @260lbs "empty" Again this will vary depending on early or late model thin wall castings or comparisons to aftermarket or Ford Performace Parts blocks.
