470 stroker shopping list

I do not think that E85 is a good option. I built a normally aspirated, single 4bbl 500" stroker with 13.5:1 compression, and ran it on E85. It made 928 HP.

I can get a small block street stroker to go over 600 HP on pump premium. I will never again build an engine for myself that I cannot run on pump 91 octane. No more E85 for me.
