E-street vs Promaxx vs 440 Source

And this is exactly why I mentioned the stroker kit... If he had that much displacement he could probably get away with the heads that he has no problem and have a great foundation...
But this is a how do I get there on heads thread...

I've got the concrete head but 318 is dead set on his bragging rights for what he can get done with an old used bottom end... With a 512 stroker kit you can fart 500 horsepower LOL...
Braggin' rights??? Get outta here...... I don't overbuild to compensate for bad tuning
