I AM GOING TO INSTALL THE ENGINE IN MY 61. SHOULD I BOLT THE FRONT MOTOR MOUNTS TO THE CROSS BRACE ON THE ENGINE FIRST AND THEN BOLT THE MOUNTS TO THE FRAME? THANKS, JOE

Re: C1 ENGINE INSTALATION
Joe, Although the AIM and the service manual both say to assemble the brackets to the front mounting plate and then install the assembly - on my 56, I bolted the brackets to the frame first and snugged up the hardware, set the rubber mounts on the brackets, and lowered the engine onto the rubber mounts. After installation, I torqued the bracket bolts. The engine has no vibrations or other abnormalities. Steve -

Re: C1 ENGINE INSTALATION
I second Steve & Ed's advice - I've place many an engine in the early year cars both with and without the body's in place - makes no difference - it's easier to set the cross brace on the mounts than try to bolt the mounts on the frame dangling the engine from a hoist. Good Luck - JohnComment

Re: C1 ENGINE INSTALATION
In the Corvette Restorer Vol 20 # 3 the cover picture shows on the assembly line
that the engine mounts were bolted to the frame and the engine lowwered to these
mounts.Comment

Re: C1 ENGINE INSTALATION
The procedure outlined in the A.I.M. (by Engineering) was intended to compensate for anticipated major width variation across the frame rails, which could cause excessive lateral stress on the upper mounts; as soon as St. Louis found that the anticipated level of variation didn't exist, they built it the easiest way that worked best for them (as production guys are inclined to do ). If the two long upper mount bolts go in vertically, don't worry about it; I've never seen one that needed lateral shimming.Comment

Re: C1 ENGINE INSTALATION
Donald, I've never even thought to look at an assembly line photo - it's interesting that the AIM and the ST-12 give a convoluted installation procedure involving shims and all and the engines weren't installed that way on the line. SteveComment
