MOTOR PLATE , FLEX PLATE AND TORQUE CONVERTOR BOLT UP.

George:
Drill a hole. Mine ended up behind the oil filter.

Yes, make the hole large enough so you can get your fingers around the bolt head to insert the bolt through the flex plate hole.

Don't make the spacers so large that there is not play between the torque converter and the transmission pump. With the spacers in place you should still be able to move the torque converter back and forward 1/8 of an inch.

dreracecar:
You can put 2 - 2" dia holes on either side of the crank hole for venting, which you should do because it gets hot in there, and thats your access to the converter bolts. You should also use ARP converter bolts as their head is thinner which gives more room between the head and motor plate. Some converters are built knowing that a 1/4" motor plate is being use and the spacers are already welded to the converter flange.I get to my bolts from the right hand (starter)side so as not to deal with the oil filter and that I am right handed.

JrFuel Hayden:
We have nutserts in the flexplate and just run the converter bolts in from the converter side. No clearance issues with motor plate, plus we buy our converters to consider motor plate thickness.
We have set-up our converter swap process so we can swap converters in 25 minutes, you know between rounds, except for the semi/ final round because they tend to push the time for the finals.

Have Fun

coupemerc:
Jon, I am doing the same thing as you. What torque are you using for the converter bolts into the nutserts? Are you also using Loctite? Thanks.
