What's wrong with the current Vortec 454 fuel rail injection system? I hear it's upgradable with Furd Injectors and such. It's not like the 350 Vortec with a spider assembly under the intake. It's my understanding it has fuel rails that the injectors can be changed and such? And then chip it, blah blah blah? Or am I missing something? Will it not bolt onto an 8.1?
No, that assembly will not bolt to an 8.1. The top ends do not swap betwix the traditional big block and the 8.1. When you say current, you realize the Vortec 7400 was out of production by 2001, don't you?
He could however swap it onto his current 454. But if he is going that far I would source a complete engine. They are the last iteration with all the goodies like roller cams and very nice flowing heads. More aftermarket support than a 8.1 also.
