I've got a set of 7.450 pushrods that'll just be laying around ( wrong length) and I've got the stock un hardened pushrods in my cam only car (torquer 2). Is it possible to use them in the cam only car ?

 

Without measuring the cam only car there is no way to tell. PR length is not a variable you can eyeball - it is measured as it would also be dependent on what lifters are currently installed.

 

One bad shift can bend those stock p-rods...get some hardened ones the correct length

 

I think those will be too long if you still have stock heads, they would put too much preload on the lifters. I would try and get some hardened of the right length, like previously stated it doesn't take much to bend the stock ones.
