Why not build a regular 360? there's lots of articles in all of the latest mopar mags. The crate engines are good, but you can probably build a conventional 360 for less money and it will be less hassle, unless you can't find a good machine shop near you. cores should be easy to find, and just phone edelbrock etc. for a combo and you might be surprised!
Well I have considered doing that as well as the 318 stroker build but I've come to the conclusion that where I live the machining and magnaflux etc would come close to if not more then the cost of the shortblock, then theres all the performance upgrade parts so thats why I decided to go with the shortblock. Plus the shortblock has 390 HP witch is real close to what i want 400-425HP. The shortblock is around $1,400 usd so I think that would be close to $1,700 cnd, I already have 360 J heads and an Edlebrock LD 340 intake so you can see why it's a good way to go for me.
