The staggered pattern mini starter off a 98 c1500 5.7 supposedly takes a metric shank and my 400 sbc has standard threads. Supposedly Scoggin Dickey makes bolts for this. I cant find them. All the local parts stores had blank stares when asked.

Maybe the threads on the 98 5.7 are standard too? Did you ask for a bolt for that application, just to look at it? from a Chevy dealerMy fabulous web page

I think this thread kinda speaks to what you are asking? Measure yours up is what I'd say.

No, none of the parts stores had them in stock. Havent been to a dealer yet, Im usually asleep 9-5. Google threads showed the 5.7 was metric but the threads where close enough to thread in, but would back out often.Si vis pacem, para bellumComment

The "people" that said that on that forum generally knows his stuff...he's on all the mag forums and don't give crap advice, none that I've seen for 3 years or so. JM$.02Originally posted by kyhunter89 View Post
I don't remember which pitches but I do know that there is an NC SAE, maybe like 7/16, and a larger metric pitch, like 1.25 or 1.0 that will thread into the other's hole but they will be noticably wobbly.
ok so i'm backin the wrong guy and prolly fos...sorryComment

I don't know the answer, but I do know that that statement is BS....I have an 87 block, it's definitely not metric threads.Originally posted by kyhunter89 View Post
I was reading somewhere recently about how the late 90s big block starter is really small and light, and it works on the old blocks, but you need to buy (stock late 90s) bolts from the dealer because the aftermarket ones don't work.
I'd start at a dealer and see what happens. Sleep is overrated.My fabulous web page

Someone on a corvette forum posted the same starter as I have and putting it on an older block and they gave him this number. Anyone care to double check?
Not sure if it has a metric shank...
GM part number is 12338064

I guess I am missing the point in this thread. If you have the metric 10mm bolt the holes for the bolts are gonna be .3937 in the nose. If you have the american nose its gonna be .375 (both plus or minus the tolerance) which is why the knurl does not come in contact with the starter case and loosens. If you need to use the metric starter and get metric bolts, you need to tap out the 3/8-16 american bolt thread to 10mm. Otherwise you would need a sleeve for the american bolt instead or drill the starter nose and press in a piece of steel tubing with a .375 ID.
A bolt with a .3937 shank and .375 thread might be made, but I doubt it.Last edited by anotheridiot; August 5, 2012, 07:27 AM.Comment

The right way to do it is to get a long metric bolt and spend an hour on the lathe, cutting knurling threading the end to fit just right. yeah rightMy fabulous web page
