I just put a motor in my car with a big cam and its the same cam i used in my last motor but it had heads. Both are stock motors. It will rev ok at high rpms but around 1000 I cant hardly get it to do anything. very bad throttle response and when i put it in gear and try to power brake it wont even turn the tires at wot. it also wont hardly idle. please help me i'm lost with this.
