408 or 540? I have recently purchased a 99 Z28 roller, and had originally planned on a 540-572 BBC/TH400, but have been doubting myself lately. I would like to end up drag racing in a 10.5 class(outlaw, etc.). I was wondering if all who have raced, if the 540 would be worth the extra $$ and hassle over a stroker LS1? Thanks
**EDIT** make the 408 a TURBOCHARGED 408

To me, I love BB a lot more and think that they have a lot more potential because of cid. I would definately go with either the 540 or 572 but that's just me. I think the TH400 is the best overall tranny too. A friend of mine is running a 454 w/TH400, Moser rear, etc and running high 9's in the quarter and it's NA so I think anything's possible with more cubes.

I only doubted the BBC because of the added weight, and the gauges would have to be changed. I never have had a big block car, but I LOVE the way they sound, and the monstrous torque/hp they make.
i think it would be awfully tight working on a BBC in an ls1 car - unless you do a tube chassis.... i think staying w/ a big inch, small block that was intended to fit in that car would be the best way to go.
my opinion.

But fwiw I think Sardog46 is building a 408 based 10.5 outlaw car with his WS6. Might want to pm him for info regarding the setup. Could be of use to you.
