Small Block/Big Block weight issue

[1HighK5]

I know this question has probably been asked a million times but I can't seem to find the answer, Not to good at look'n. Any way what is the weight difference between a Big Block and Small block and will it make my lift sag if I put a Big Block in my truck. The 305 is almost dead I can't help but be a "Throttle Jockey"

not too much difference. 110Lbs or so. Well worth the weight difference

It all depends what you're doing with it. I have thought about doing a LS1 in my race blazer just to get another hundred pounds off the front end over my current 400. Still, it's hard to beat the 400 on a cost basis vs. changing over to the big-block.

when I dropped in my big block, it dropped the nose a little over 1/4"
