Need some weight information

[tyoneal]

Hello, I am planning how the weight will be distributed on my car. If possible, I would like some information on the weight of various componants.

What is the weight for a sbc with Aluminum Heads/Iron Block?

What is the weight of the different accesories? a/c compressor, Power steering pump, Alternator

What is the weight of a sbc AL. block/AL. heads?

What is the weight of a BBC with Iron block/Al heads?

What is the weight of a BBC with AL block/AL heads? (World products says 471 pounds, does this sound right with most AL BBC blocks)
--------------------------------------

What is the Front/Back weight distribution (in %) of a 69 Camaro with a sbc, Fe block and AL Heads?

Same question sbc AL Block, AL heads?

Same question BBC Fe Block, AL heads?

Same question BBC Al block, Al Heads?

Assume Standard Mounting location of the engine
----------------------------------------

Does the type of transmission have any real impact on the ratio?

Thanks in Advance,

It has been a long time since I thought about a big and small block chevy.

Interesting. I'm guessing that the difference in LS1 weights are due to flex plate versus flywheel? Also, from the weights comparison, I'd guess that the SBC's don't include the weight of the flywheel?
