I've read on a couple of forums that you don't actually need to use high temp paint on an engine block as it doesn't get nearly as hot as the exhaust manifold or brakes.
Someone also said that the block wouldn't get as hot as the exterior paintwork might on a very hot summers day and you never see exterior paint cracking or flaking unless it's exposed for a couple of decades to high heat in a hot climate.
So, before I go and paint my block, what's everyones experience of this?
Should I use high temp paint or will normal paint be OK?
