Default Pump gas?

I have kicked around the notion that when my current motor has "dried up" that I would entertain the idea of a crate engine. My biggest question is that I want to keep the car able to run on 87 Octane "regular pump gas."
Is is possible to find a 400hp crate which is able to run on regular pump gas (87 octane)?

I bought mine straight from Dereby performance who builds the engines that year 1 sells. I went to the shop in Texas and watched them dyno it. We did it with their carb and dist. Then we switched to my carb and dist and dynoed it again. Great motor and company.

I pulled the trigger on this engine today - Y1 told me 2 weeks minimum, 3 weeks likely, definitely less than a month. I am very excited.
I am putting this engine in w a T56 6 speed trans out of a 95 Camaro.
I asked and they said the engine is internally balanced, 1 piece seal crankshaft.
I know the LT1 engine has balancing weight on the factory flywheel, so what should I do for a flywheel? Just get it balanced?

This motor will do great with a factory to small stall converter. That is what I was told by derebery before i bought the motor. A 3000 stall sucks on the street my old motor had it and did not do crap until 3000 when the converter would flash had to have it due to the big cam edlebrock performer rpm cam.

How does a loose converter effect horsepower on the dyno?Once the converter flashes your horsepower should be the same,unless the flash rpm is higher in the rpm band in respect to the engines HP output. Are all these Year One engines dynoed?When those Hp figures are given are they dynoed with accessories?Anybody have any RWHP numbers for this engine?I am not trying to bash this engine but the #S seem so high for such a small $ amount.

Got my engine already!!! (Less than a week turnaround time).
411hp,426tq.
I noticed that the supplied flywheel has a balancing weight.
Y1 told me the engine was internally balanced before I ordered it.
Im no engine guru, but if theres a weight on the flywheel, that means its balanced externally, right? I need to know so I can get the correct flywheel for the T56 conversion. Does anybody know more about this engines balance?

Flexplates are balanced like all things by the use of weights. Some have little weights, some have big weights. Flywheels used with internally balanced engines are zero balanced. This means a flywheel and engine are in balance whether they are together or not. It also means the zero-balanced flywheel can be indexed on the crankshaft in any position without affecting the balance of the whole assembly.
