Uhhh that is a very broad, speculative question. Cam specs? CR? Pipe sizing? Lots of additional info needed

Maybe 225 at the wheels.

Why are you boring it 0.040" over?

Re: L98 Horse power????

I had edelbrock shorties, edelbrock alum heads, zz9 cam shaft, mini ram intake, 30lb injectors, 52mm throttle body and electric water pump, and a perfect tune, and only put down 292 to the rear wheels. So your going to need quite a bit more to reach that 300rwhp mark
