318 build. what would you do?

Yep long story short is that yuou will spend as much or more on the 318. As soon as you decide to go much more than stock, I would get a used engine for $100-200 from a junker or someone selling one. Make sure your convertor and balancer are for the 360 external balance type and build the 360.

No replacment for displacement!
You will have an instant 50-60 HP and 60 or so more ftlbs torque all things being equal.
318s rev higher tho. im planning on makin a 384 stroker. 4 inch crank. flat top pistons. then maybe bore it .30 over with flat tops. 509/292 cam. i have a 650 edelbrock but i might get a 750 Holley. 727 automatic.. with a 4 inch crank it wont rev as high but it should have torque out the wazzoo. im just lookin for insight on what you guys would maybe do. but i dont want another engine for it. i have nowhere to ifnd a 360/340 for it. got a 440 but thats just too much trouble
