With the topmount, sc61,E85, that should be no problem. The rods/piston combo, with stock sleeves should be fine. The E85 will allow you to add more timing and boost, and still keep it safe.

with E85 it should be much safer to do so

That sounds like a great setup...i would have no hesitation pushing it over 400whp. Its all in the tune and since you're running E85, that gives you even more potential to make power.

whats a good tuner around the Northern Indiana area. he was gonna have Superdave from the Whipfactory but i was told he moved to Florida? So now we are back on the hunt for a tuner that makes power with good Reputation.. Jeff Evans and Tony1 we would loved to be tuned by them but too far for travel must be done over a weekend

10.0:1 CP Pistons, Eagle rods, 81.5mm B18c1, stock sleeves and GSR head. E85 fuel tuned with S300. 400whp and 331tq. So far so good. As long as the tuning is good he should be just fine with stock sleeves. 450+whp might be pushing it though. Click on the links below to see my dyno graph.
