bigd65,
I have a four swirl hole carb spacer/adapter on my truck. The spacer made a difference on the low end torque. I can cruise at low rpms with out any problems. Currently I'm waiting for delivery of my new intake, an Eldelbrock AirGap intake. I can't wait to see how much of a difference this will make on performance. The new dual plane intake should work great. After the 305 reaches the end of its life, the intake will be fitted to a 383 Stroker. I plan on buy a crate 383 with about 400+ horses. That should plant the rubber on the street fairly well with a differential locker.
