Re: Small Block weight v. Big Block weight?
if youre comparing same displacement the small block will be a better choice.
if you want less weight the small block is a better choice.
If you want big power and speed the big block is a better choice.
adding aluminum heads and intake manifold, mini starter and waterpump to the big block greatly reduces its weight and makes it perfectly manageable.
its a 150lbs difference.some dont like that much extra weight sitting in the front. others dont mind it. as far as speed goes, im sure the 20hp you need to overcome that weight can be found somewhere in the extra 120 or so cubic inches you have to work with.
oh yeah, im sure the small block would be easier to work on though cuz it wont be hogging up all the space in your engine bay
for the price of am all aluminum 427 you can probably build a hemi headed 557 making somewhere near 1000hp.
