Has been great. I did some changes yesterday. I removed the 625 AFB and replaced it with a dual feed 750 Holley 4160 along with a one inch spacer. I also replaced the factory distributor with a Jegs machined unit. From what I have read it is the same Mallory piece that Mopar Performance used to put out. The carburetor really woke the motor up!

I have 15" of vacuum at a rowdy 875 rpm idle (in neutral) and the motor revs right now. I drove it for the fist time earlier today and it is a beast. Instant power. No bogs, no lags, no stutters. Severe case of wheel hop, but I was expecting that from the beginning.

I am very pleased with how it has turned out. I am going to run it up to Wichita Dyno (http://www.wichitadyno.com/) next week and get the final tune done and have some real world HP numbers.
