max compression for 93 octane
2 questions- anyone know the max compression i could in my 351W with aluminum heads on 93 octane?? do you think it would be worth it to run higher compression and use octane booster??

you can build a 351 to run on somewhat high compression and pump gas, but you need the advice of a pro engine builder to pick the right combination of internal parts to make it all work correctly without fear of detonation on pump gas. I think about 10.5:1 like MD already said is about as far as you can go and be safe, but it easy to get the wrong combination, so get some pro advice. You might try talking to www.coasthigh.com or www.dssracing.com to see what they would recommend.

well the hondas can as they have knock sensors to cut timing out of each cyl..his ford can not do this ..so the 10.0-10.5-1 would be about it..why worry about going any more?.. the lil hp you get from it with all the hassle isn't worth it

Everytime I think of Summit I think of that guy with a mullet on the toilet in front of his trailer ordering parts for his Camero... haven't seen that pic in a long time...
