Starter is on the driver side on my jeep 5.9l
hp per cid and rpm
1 hp per cid is kind of the middle ground of performance engines compromise between mild to wild something like a 224 cam airgap 650/750 carb 9:1 cr and headers with a powerband 1000-5000 rpm and a 5500 rpm ish redline with mild stall and 3.23-3.91 gears. Under that more like a truck powerband stock gear and stall and over that goes towards streetstrip to full race engines. eg. 1.25 hp per cid is a healthy street strip type engine with aftermarket heads 235-245 cam airgap/single plane intake 750 plus carb 10-11:1 cr 3000-4500 stall 4.10-4.56 gears etc.. 2500-6000 rpm powerband 6500-7000 ish redline.
Heads are gonna be the main deciding factor of how much power you can make.
