Yeah I thought about that!
But it is alot more involved than people think.
Like which accessory drive to use? The 4th Gen F-body, the Vette or the truck? Problems in hooking up a workable AC and power sterring unit. Remember this is for a DD. I am not getting into the wiring harness issues.
This one issue when it comes to LSx conversion that no seems to talk about much is the transplant LSx engine itself. What is its history ??How many mile does it really has. How was it maintained??
You see you can't in could conscience just pluck in an unknown engine in a car that you and your family are going to ride in without a good engine rebuild. Even in that last episode of Horsepower TV they went about how to do a total rebuild of a late model Mopar 5.7 liter Hemi coming out of a wrecked Chrysler product into a muscle car. That where the cost really goes up.
I have come to the conclusion that is is easier to build a rad LTx than to change all those ancillary components.

thw 18 degree stuff you could do but you would have to run a little valve an same with a 15 degree head.then you would kill the power of what it should be due to that fact..you could try an notch the tops of the bores to fit a lil larger valve in it..remember the sb2.2 heads are a 12 degree head an n2o daves heads had like a 2.15 intake which is small for a sb2.2 head an even small for 18 degree heads..just keep that in mind its not like your using a 4.155-4.20 bore your working with a 4.03
