is the starter painted,especially the mounting pad?and the block?may be a bad ground.you using starter mounting bolts w/ the knurls on them?

dont buy MSD starters , this is the result. yes they were shimmed correctly.

whoops..

nice!


total junk


wasted

557 cid, 650 hp, 9.3 compression. starter bendix's half the time wouldnt come out all the way, buzzing the ring gear. put the exact ring gear back on and used some new tilton super starters and havent had a problem since. MSD told me they had problems with them, then when they found out i wanted labor time to pull 2 boat engines they lied and said they never had problems with them. then after six months of avoiding me the best they could they agreed to pay 2K for the repairs. which they reneged on 24 hours later. keep in mind this ruined my once a year boating vacation and knocked out over half my summers boating. took ten years to save and build these engines. MSD products are crap. btw at least summit stepped up and refunded the starters that MSD still had in their possession. screw their ignitions too, been using daytona cd-1 boxes, they are great.

Thanks! - Did you do the (+) from the battery to starter? Or other cables also?
