Hard start after engine warms up - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've asked this before but have tried a few different things. So I swapped the 305 in my truck out for a mild 350 and it hasn't been drivable since. Engine will start and run pretty good but once it's been ran awhile it will turn over super slow. I've tried a newer battery, I've had my starter rebuilt and i've bumped my initial timing down to 12 degrees. Then engine is pretty mild stock bottom end a mild cam dual plane intake headers etc.. so I don't think it that's I need a mini starter. Anybody have any suggestions/is there a way to test the starter wiring?
