Will this radiator work?

My 68 Barracuda is eventually going from a slant six to a 360. I have a 22" radiator from my 66 Sport Fury that had a poly 318. A third row was added to the radiator. Will this work in the Barracuda as far as cooling goes? Will it be enough? I know I have to check the fit as well but, after having 2 cars in a row with cooling problems (68 Fury with 318 and the 66 Sport Fury with the older 318) I'm gun shy when it comes to cooling (p.s. I did "everything" and spent a lot of money to have the problems with the other cars fixed to no avail). Thanks
