The hamburger starter just quit on me. I ended up purchasing a Jegs 10040 pro start'r. Nice unit but the fit with a 153 tooth small flex plate is not exactly a good one. I did figure out how to get it to fit on the motor now after removing some material from the mounting block to clear the oil pan rail. Then I had to cut the end off the mounting bolt for the starter motor itself and file some more off of that area. Now the gear is .250 away from the flex plate and the spec is .060"-.140". The interesting thing is there are some test marks on the pinion that are only .250" deep and that is about what I have now for engagement into the flex plate. I am not sure if I should bother getting .125" more engagement or just run it.

i had a similar experience with my Summit starter. .250" was all i could get. its right about where the factory starter was engaging so i left it alone.

The CSR starter only engages .250+/- .010 On mine with 13:1 +/- .2
I don't think you have a problem as long at engages and lets off quickly.


How did you attach the starter on a 400 block?

Mine has no provisions for a straight pattern.

Had to use the outer bolt and bolt the other to the motor plate horizontal with shims and works well!

10 sec and Adam,
The run in test marks on the gear are exactly .250" so maybe it is ok as is. Both of yours have the same amount of engagement.

This starter is far from JUNK! Take a look at the specs that thing will turn over an 18 to one motor. It is just not a perfect fit with a 153 tooth flex plate. A 168 would have been a slam dunk but hey it is hot rodding so you have to machine stuff sometimes.

The boss is there on the 400 block for the straight starter mounting hole. When I was building it I just carefully measured then drilled and tapped the hole with no problems at all. The motor plate mounting seems cool and if it works well I guess it is ok. You could always drill the hole any time the boss is there for it. Then you would have a 3 bolt starter. Cool

Like Paul, I drilled out the block to accept the starter. Has worked fine for a bunch of years. I have a tilton starter.

I was so worried about everything else I never looked until the engine was in the car and bolting the starter on. LOL
That was the last thing I was concerned about until I tried to put the inner bolt in. LOL
That was an oh fu## moment.
