was shifting the car at 6000 and thought the traps at 6200
I will assume this engine is gonna make more power than the last one.. if so you will most likely go a bit higher in the revs.... so what kind of duration are you thinking

I am guessing you will be shifting at 6800 and running low 10's now

Ok lol I do not ! will not run it that hard. 10.90 is just fine .in fact I thought I would shift this lower..be easy on it .live awhile
You wouldnt be running it much harder than your old engine... a few revs wont hurt that(not unless its got stock rods)... but if you have aftermarket decent rods then I wouldnt worry at all even if you went to 6800.... hell Jamie... you sound like you want to idle to the finish line... LOL

You have two choices, use it or not use it I would make sure it was alittle on the rich side with the E85 and not to much timing and go bracket racing Who did or who is going to do your E85 Carb? I had AJ Castilini(SP?) do mine, it is real sensitive on the dyno to jetting, one jet size either way would make it lose power BTW, E85 and bracket racing are made foe each other, hardly any change in ET from early morning to late afternoon Don't tell anyone else that though AKA I would worry about te main webbing on any stock 440 block if you decide to RPM it much above 7000 RPM on the edge on the tune up Run it slightly fat and don't push the total timing and you should be okay

I did't mean for this to happen. I got a good deal on this short block. so I bought it. He told me it had 12.5 to 1 with his 75cc heads. LOL wrong ! and it had small domes on it. so now I am try to do the best I can with what I got.
Your thinking is correct, that if you optimize this combination you will likely be over the limit of a stock block unless you go easy. But going easy is tough to do when you want to see what it can do. Why not take the domes off and rebalance?

Why not put a bigger cam in it, back the timing out a little and rev it to maybe 63-400. That way you're within your comfort zone but will still probably run mid 10's. I shift my .590 at around 6300 with nearly 13.1 comp, trap at 6700 and it's pulling like a train. Mick

The CR is not to high,and its perfect to run E85 and even better to run alcohol.I think you would like the alcohol better than the E85 and it would make a lot more torque,more torque=more power/speed with out having to raise the RPM level.
