MOTOR PLATE , FLEX PLATE AND TORQUE CONVERTOR BOLT UP.

(1/3) > >>

grapro:
I just bolted my sfi flex plate on my sbc and noticed that it is fairly tight to the engine plate not giving enough room to bolt the convertor up. Looking online I notice some people sell a spacer for the crank but i'm not sure if this is what I should use. What do most people do or am I doing something wrong?

fuel749:
How thick is your engine plate? With a common 1/4" plate there should be room enough for the bolt heads, but you will need access/vent holes in the motorplate to get the bolts in. 1/4" spacers between the converter and flex plate unless your converter manufacturer provided taller mounting pads.

Are you saying that once the flex plate is bolted up the heads of the bolts that hold the torque converter hit the engine plate,

or

You cannot get the bolts for the torque converter into the flex plate because there is no room between the flex plate and the engine plate?

grapro:
You hit the nail on the head.
Yes I cannot get the bolts for the torque converter into the flex plate because there is no room between the flex plate and the engine plate?

grapro:
Sorry one more question, are you allowed to drill ahole in the motor plate to put the bolts in? Because if you are I can do this and just add the spacers to push the convertor all the way in so it is engaged.
