Can a 400BBM w/cheap aluminum heads compete/dominate against the street LS?

Sorry for the delay. Anyways some basics about 13.5 - 14.0 comp a modern solid lifter cam about 268 - 274 dur @ .050 some decent rods (eagle or such) single plane tall manifold 950 carb. should be a killer set up, now a 8 inch convertor a set of small slicks should be over the top for most ls's. It would be a cheap build and easy on parts. Look for used convertor, manifold and carb. slicks and use a trans shield. You will just love it. And a stroker is always great if you got the extra $$$. And it is fully streetable.
My 451 is close to thous numbers. I believe a little less compression. (Block was not decked to build. Thus pistons are a tick in the hole.) I'm guessing around 12.5:1. Running to a 1050 E-85 metered Holley 4150 style carb. (E-85 to accommodate the higher compression.)

The jury is still out on my thoughts of E-85? Does go thru more fuel. And needs flushing more frequent. Smells a little funny? Lol. But in Minnesota? ALOT cheaper than race gas.
