i did one a few years ago - 3.23's and a 4 speed :

kb 400 pistons

stock rebuild on the heads

crane cam 4.80 lift intake 494 lift exhaust - I cant go to the web site anymore for more specs..lol

anyway other then those 2 changes the rebuild was stock and it ran mid 13's @ 104 in an E body.

Keep in mind it needs to be blueprinted, the deck heights and head volumes need to be corrected.

here are 2 vids of the car in action
