Pick me a mini starter

Yup, compression, correct; but with more cubes, you are compressing more air & at some point an under-powered starter will struggle.
 
On another note, after speaking with Indy, for kicks I went to Mancini to check out their starters. After looking at the Mancini starters, I wandered into the Mancini PowerMaster section. The 9523 is listed at $316.99 + shipping there so I looked into the same starter at Summit - $289.99 and free shipping. Even if Mancini matched the price (As for product pricing we match summit on ALL main line brand products to be competitive in pricing to get you the best pricing. Outrageous shipping fee from Mancini Racing post #67) you're still looking at shipping...

Now back to our regularly scheduled thread re: Pick Me A Starter.

but it has to be noted that on a v8 you have 8 cylinders and just one needs to fire to start the party
gotta be easier to start than a 4 or a 6
more friction/compression to overcome but way more points in the 4 stroke cycle to actually start
harder to turn but quicker to start...
Torque and then by association any gearing in the starter and the ratio of ring gear to pinion come into play..
my starter runs fast my engine turns slower than yours mine has a 25 mm 9 tooth pinion your has a 34/5/6 dunno bigger pinion running on a similarly sized ring gear
if you used my starter with your pinion you'd use more current, the starter would run slower and get hotter, your engine is bigger it has more cylinders and the gearing has an impact

so i can see why torque is key
because that leads to consistency in engine rotation, speed aint the be-all and end-all like it would be if the engine had a magneto style ignition we aint starting a lawn mower
The ignition has its own battery supply which is good enough for the length of time the starter should be running

The starter recently crapped out on my 408 and I purchased a Summit brand HP mini starter and it spins my 10:1 (200 psi cranking pressure) like it’s a worn out 4 cylinder. To top it off the battery is over 5 years old and I can tell it’s not as strong as it used to be. It cost around $130 if I remember correctly. I wouldn’t be afraid to use it on your 528 seeing how it works on mine
