Just my 2 cents, but....
To go 6.40's without nitrous, you'll need W-2 or some other good aftermarket head with other complimentary parts. Obviously we don't know what all is in the engine now. But more importantly, you'll probably need quite a few upgrades to the safety side of the project. At 9.99 and faster in the 1/4 (forgot the 1/8 mile break), you'll need an SFI 5 driving suit, balancer, flexplate, probably rollbar and chassis upgrades, etc. You need to get a rule book for more specific info. While it's do-able, just SS leaf springs are not the best set-up for that ET.

Welcome back & good luck!
