engine feels weak.

put a different engine in my gmc(see sig) and it feels really weak. i didnt expect a rocket, but it should have some more grunt. when i boot on it 2 kick the tranny down, there is a nast backfire outta the carb. its crazy. timing is 8 btdc. the truck seems like it doesnt wanna rev past about 3500 when i shift it manually. if i try to take it further, the backfire is back. i dunoo what 2 do. the carb seems to be tuned right, but im not sure. it revs fine in neutral, but under load it goes funky. thanx in advance
