Main cap girdles re-discussed
600hp, waste of money and time putting a girdle on a SB mopar.
SB ford OEM blocks were NEVER designed for 1000hp and cut themselves in half no matter what bandaid is put on them. Try that 1000hp with a production based mopar, get the same results, broken blocks. Only a matter of time.
Girdles on a SB mopar do nothing to stop the issues of the block breaking or cap walk.
Want peace of mind, buy a better block if you can find one.
