small block chevy starters

I picked up a starter for my engine but the mounting holes are different. The starter I purchased has diagonal mounting holes, but my block has holes accross from each other.

I need to exchange the starter but am unsure what to ask for.

The engine is a crate replacement 5.7

 

If the block has 3 bolt holes in it then it should mount up you might have to shim it a little? or get one from the med to late 70s trucks or cars they should be the same.
Good luck.

 

I've found two starters, one with bolts across one bolts Diagnal. I think thats to match starter to flywheel.

 

You need to see which flywheel you have. You may have to go with a mini starter .

 

you need to know what diameter flywheel/flexplate you have . the staright across starter is for a 153 tooth 12-3/4" diameter. the staggered is for 168 tooth 14" diameter

your block should have 3 holes so either starter can be used

what diameter flywheel did you put on it?

 

If you have a starter laying around that has the correct snout on it just change snouts no big deal

 

The starter I took out (it wasnt working) had the straight accross type.

I guess what I meant to ask is what do I tell the parts counter dude?

What is the correct application for the straight accross starter?

 

1962 and newer V8's have three starter bolt holes in the block. Only two are used to mount the starter. Starter end castings vary with flywheel diameter. The starter casting with bolts in line (at right angle to the engine certerline) is for 153 tooth Flywheel. The starter casting with bolts offset from a right angle to the crank is for the 168 tooth flywheel. Just ask for anything from these years..

 

Guess at it like i do. My guess would be, let's say a 69 Malibu with a 307 and a Powerglide would have the smaller flex plate, and a starter with directly opposing bolt holes like the one you described

 

Groucho has the answer, the two basic types used in the 60s-70s are:

the small flywheel with the straight across holes, one long and one short bolt. Used on 6 cyl and small V8s.

the large flywheel with diagonal bolts, both long. Used on bigger V8s.

 

Thanks all!

 

Two questions

1-did you turn the old starter in? If not there's the right snout just change it. It's not that big a deal to change snouts. That's the only difference in them

2--If you turned it in why didn't you check before you left the store that you had the correct starter?

 

my non trad starter has eight mounting holes,
my late sixties block has three
and my ancient safety bellhousing has two...

 

for a straigth across 153 tooth flywheel starter try Napa # 246-4785

 

I plan on keeping this car I'm working on for a while... So, I paid the $44 for a lifetime warranty starter at autozone. I didnt have the old one out yet. It was from my driveline donar car, a 1987 Caprice with a recent 5.7 4 bolt crate motor and 700-R4. I initialy ordered for this application, but the bolt hole pattern is different. The block has the 3 holes, but the snouts do look different. I'm going to return this one and ask for a '69 307 / glide/ small flywheel and bring in the old starter to match up.

Thanks yall, your help is much appreciated.
