Engine weight

Hello, I have a 79 Vette w/ a stock L48. I am going to replace it w/ a 383 aluminum head motor w/ aluminum intake. My question is, what do these two engines weigh? I am trying to find out the difference in weight between the 383 and the 350. Thanks, Al

I have searched for engine weight info before with not much luck. maybe you will have better luck with just finding the difference in iron heads and aluminum heads? thats the only difference isnt it?

Haven't actually weighed one, but am comfortable with the 535# estimate I've been using for an iron SB 350 w/alum intake, tho that appears slightly high according to previous posts here.

Evidently you are still using the 535 lbs. reported for a 59 C1 283 w/Al. intake.
