I personally have sprayed 250 through a single nozzle on my stock bottom end LM7. However i do have a fairly large cam in my engine to do so. You will want to watch your plugs and pull enough timing (Around 10 Degrees to start). I would recommend running a 8 range NGK spark plug.

not sure which way to go for a trans. I just picked up a new trans specialties glide with 4500 stall and a brake and i have 4.10s. But the car now has 2pumps in the cell from the previous owner and he just drew the extra fuel from the cell for the spray on the last motor. Its going to have a set of ported 806 heads and a NX3 cam. that should love the shot.
