With modding the head of the blaster of my grandfathers (was mine), will it improve any low end power? Even just a little would help, everytime I put it in 1st gear, it will put for a sec, then it just dies cause it dont have any low end. I could go and buy a 13T spocket if I wanted to, I just wanted to know. I also can afford to run on 93 octane, but i really dont wanna run race 110 gas. Its $4.92/ gallon here.
