700 Hp on NA pump gas

No boost because it is not necessary and adds complexity to something that is WAY complex already.
I have been in touch with Scott @ Eatmon race parts, and an R5/P7 build, being the top of the bar, does this quite easily. 10.5:1 745HP 540 ftlbs and only 358CID!
I have found a TBI unit that can fuel this with data logging and other features that may simplify my life.
I am not ready to pull the trigger on this yet, there may be some space (height) constraints involved.
I also found a 700HP R3/W2 build the does this but the comp ratio is high (13.2:1) no telling what the DCR is though. They are both about the same cost.
I did confirm with TCI that the bell housing will bolt to the R5 block.
This is just the beginning of the process.
