C8 Big Block

"Cast up new heads", it's just that easy. I wonder what the weight difference is with a cast iron block?

Dart BBC----4.25" bore 280 lbs., 4.5" bore 260 lbs.
World Products BBC----approx. 270 lbs.
Brodix Aluminum BBC----160 lbs.

GM production 350----181-187 lbs.
Dart SHP block--------175 lbs.

"the LT1 and the LT2 weigh the same, 472 pounds with fluids. The extra weight comes in part from the block-mounted oil tank and the redesigned crankshaft, which has a slightly longer nose to accommodate the scavenger"


"a 454 with aluminum waterpump,heads, and intake you can get down near 650LBS"

Yeah, given what he's spent on the car and all the custom parts, I'm a bit perplexed why he didn't just spend a bit more of his pocket change and get an aluminum block. It would make for a better vehicle weight comparison after he got everything put back together.
