Can an evo engine be mounted in a twin cam frame? Would it be a simple bolt on ro are there significant primary drive issues, engine mount issues, etc?

 

Why would you want that? Evo frames are a dime a dozen. If you have an evo layin around, cheap enough to find a frame for it.

 

Evo motors mount to the transmission different than twin cams. You would need an evo era trans to make it work.....In a dyna anyway

 

Better fire up the welder, you have a bit of work to do
