I took this once before if memory serves me correctly they was all 20-40 degrees range difference but will double check when I get the chance
No water in oil no oil in rad what would you consider cold far as temp range wise
I wouldn't think so I never messed with it when I was in there the 10k miles I put on it I didn't have any issue just happened outta the blue...
Got a 1984 359 13speed 3.90 rears Its a cummins recon motor just done a inflame laid down just under 10k miles after inflame now it has no power...
