*If* you could buy one of those engines it wouldn't fit, it's nearly twice as long as a 13B engine and it's variable intake would require an incredible amount of fabrication work to fit under the bonnet. You'd have better luck on all fronts with a 20B engine.
a 26b is usually make from 650-1600hp depending on set up.
