want to bulid a new big block out of an old one

hey, i have a 454 short block that i would like to run a square port head with, but the thing is i want to twin turbo it and i know that fuel injection is going to be better for that. what i want to know is how i should go about doing this. is there a way to fit some vett stuff on a big block? or dose some one have a race ready kit for a very good price.

i have another question aswell. what all can u pull from the vetts (any year) that take little or now work to make fit on a 66 chevelle?

the main goal with this car is to build a old car with the latest and graetest technolagy GM has to offer on there cars stock or after market.

thanks for the help
