Big Block vs Poly

I found some numbers on engine weight, for the Poly, LA and B Engine.

273-318-340 LA - 525lbs
360 - 550lbs
B Engine - 620 lbs
RB Engine - 670lbs

B Engine with aluminum heads, intake, water pump housing about -530lbs
Poly with LA block and aluminum intake - 530lbs
LA with aluminum head and intake - 455lbs

So with the Poly/LA hybrid, and the B engine the same weight or so, the B engine has the advantage with the extra cubic inches.

I already have a Small Block Stroker in another vehicle. So I don't want to build another one for this project. I can get the weight of a B Engine down to about the same weight as a production Small block, so that shouldn't be to bad. Along with moving the battery to the trunk and a set of fiberglass fenders I picked up for a couple of bucks. I think I can get a Big Block to handle just fine.
