Inputs on a home built 318 for red light to red light fun

Id get a 340/360. Youd need the top end from one of those engines anyway, If you are scrounging up half of a 340/360 why not just get the whole thing...:)
Why can’t you just freakin help the guy out building what he’s got instead of being a jerk?

Better yet, give him a complete 360 for free since it seems like there is no issue for YOU to do a swap. For sure you must have a spare 360 ready to run or build in your stash.
