Pick me a mini starter

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
