If the engine has a dog box with flat shift then the very narrow power is only a problem coming off the line and the power management needed to reduce the hit in first.
I quoted for a 800hp drag engine for South Africa in a MK2 escort he thought it was too much money and spent double it trying to achieve it and had too small a power band and went slower as always fell off boost in the launch /1 gear power management.
A 1300hp engine is very cool 😎
