Looking for advice on a blueprint engine.

If you're changing transmissions I'd recommend something with an overdrive. We're putting a similar engine in a Camaro this winter and my buddy is going with a 700R4. It's an easy swap and is going to allow him to use a little more gear for around town fun and still be able to take it out on the highway. Just my two cents...
With the 3.07 first gear helps get things rolling. Depends on expectations.
PHR magazine went through a 1984 Malibu wagon that had a leaky 305 4 barrel engine and TH200 transmission. They rebuilt the engine with a 3.75 stroker crank for 334 CID and installed a 700R4. It was under 16 seconds in the 1/4 with 2.56 gears. Fuel economy was real good. Now in a truck, 3.42 gears would be good.
