I am redoing my motor in my car this year. I plan on getting a used block and building the motor from there. I found a 302 block but it is out of an econoline van. The guy said he had two of them. One van was an 86 and the other was a 90. My ?? is if there is any problems using these blocks in a 1990 Mustang if I just use the block and have it machined for what I will use it for. One person told me the blocks were different the other said it would work. Any suggestions are appreciated
