I am in the process of rebuilding the motor in my 1970 GTO and lost the bolts that go to bolt the motor mounts to the block I think they are 7/16-14x1" ??? So I look on Summit Racing why is there 6 bolts in the ARP 190-3102 kit and I only need 4 It would be nice to find a chart on bolt sizes & Lengths

Hello

because the later/newer engines need 3 per side ..to hold to the block .. U shaped bracket and
5 bosses on the block ... you have 2 ..in the pic .. early engine ??
I have a correct set of 4 originals with cross cut heads like water pump bolts for mount to block
give me a call tomorrow
I will get a set out to you
any other hardware ??
