I'm thinking if I use aluminum heads, intake, etc on the B motor that the diffrence would'nt be that great, but I really dont know. Anybody have some info on the weight difference between the two? thanks!

I strongly suspect that a fully lightened B or RB for that matter (alum heads, headers, alum intake, alum WP, light weight starter, etc.) is LIGHTER than a fully dressed, all cast iron small block. It'd sure be nice to know for sure.

Take that same weight off a 360 and you even further ahead of the game.

Oh well, until someone actually measures the difference..... Oh, and of course you'd be ahead with the same weight saving measures on a small block. The question here is can you make a big block weigh the same or less than a stock, all factory small block c/w with all accessories and I still believe the answer is yes.

I'd say it wouldn't be that great but you are wanting exact. Someone here will know to the T. www.bigblockdart.com and www.forabodiesonly.com. Obviously the heads & the headers are what's really going to help you. live every 24 hour block of time like it's your last day on earth

I know how the car handles with the stock 273, so the aluminum headed 400 should not feel that much different...except for about 200 more lbs of torque !!!...lol
