One Block Too Many Options. Please Help
OK well it starts like this. I have an 1980 mustang coup. It has in it a 3.3 straight six. I am building up a 1985 302 and of course want as much power as i can get. But only power that will be good for streed aplication. I need to keep it under controle to some degree.
So here is some of the problems. Do i put on the 351C V2 heads (already decided against v4 because it is too drage strip and not street) or do i get a afermarket head that would require no adaption for my motor.
Do i get a 331 stroker kit or leave it the way it is. This question is bothering me alot. i just don't know if it is worth the extra money. i want a really good working engine but not something that is so close to the edge.
I already plan on changing the cams and rockers but like i said the two main problems are the heads and crank.
If people have information about these options and would like to help me from making big mistakes i would be very thankful.

You have to decide what your plans are for the car and how much will you be driving it. Once that is decided then you can build the motor to what you need. Oh also how fast you want to go.
Hope this helps!!

there is no such thing as too far, especially since you are only using it around twon by the sounds of it. if you want to use a stock 302 block I would recomend using an 86 or newer....they are a little stronger than 85 and older ones. take a look through a summit catalog and read some build up in magizines. you should aim for 450-500hp at the most..these blocks can't handle much more than that, even with a main and valve train girdle they are only good to about 600hp. i suggest getting yourself a nice 331 long block from DSS or CHP with AFR heads and the ,aim girdle option....a very good bang for your buck proven to run hard and strong for a long time...

you seem like a pretty smart guy when it comes to most stuff but on this occasion you are wrong. Don't feel bad, most people don't realize there is a difference, let alone a considerable one. I didn't either until I came across this article.

Don't believe everything you read. I've worked at machine shops, built many engines and there is no difference. Just look at the casting numbers on the blocks, above the starter. There is NO difference, I have an '85 302 block in my car and I didnt notice any difference in main or deck thicknesses anywhere. There is no difference in 85-97 302 blocks.
