You really have already good parts for a good engine.
The AFR heads are really the best for there price.
You could put the 331 kit in your 289 block if you like.
The 5.0 HO has cylinderwalls with a length of 13cm.
I have seen two 289 blocks whitch have the same lenght.
The mare, that you can not build a stroker with a 289 block is not correct.
You must messure your cylinderwalls to check this out, if the are 13cm long, you can stroke the block.
I do not have any problem with the body of my car. Mine is a groundup restored and really solid car. If yours also, dont worry about the body.
You are right, the cooling is a problem if you use your power all the time.
With cruising speed or normal traffic speed I have no temperature problems. But I will put spacers under the hood to lift it in the back.
This helps the engine really mutch.
I would not intend to make so much power. My goal is to get round about
300 DIN PS ( 325 to 350 HP I think) but power from idle.
Next week I go on the dyno, the power from idle, I reallly have :-)))))).
The engine is like my old 260 in his character, only twice.
Have a nice time and a nice ride.
