Do I go with the 318 or the 360?

[dirty white boy]

The converters can interchange with the correct flexplate.

yes and theres other ways to skin that cat,..was pointing out that it needs to be considered and thought out with in his plans...

OP, you have put out a start to good info but there are a lot of missing pieces to get past the most general advice that has come so far.

Get the following info as preciesely as you can:
- Cam maker and PN
- Intake manifold
- Heads and any head work
- Carb make/model would be nice

BTW, a 318 with the KB pistons will generate some pretty good cylinder cranking pressures and that will give you good torque at lower RPM's versus a stock bottom end 360 with the pistons down in the hole.

Also what was done to the heads will be more critical on the 318? If stock, it is not gonna get ANYWHERE near to 425 HP.

I have a family friend who is a VERY knowledgeable person on any and all things Mopar and he himself inspected everything on both motors inside and out so they both check out—aside from trying to check the validity of the engines do you guys have anything to say about daily driver performance?—and if you’re going to ask me well why didn’t you ask your friend if he knows so much about mopars, I wanted to post here to get as many different perspectives as possible on what they would daily drive if they were in my position

I can't speak for others, but I can't say much more for the daily driver question without the info asked, particularly about the cam. The cam can make it a piece of crap for daily driver, or it can make it great. The main thing about a daily driver is that it should have a wide torque band reaching down to the lower RPM ranges. Too big of a cam in either engine will kill that.

Do you think you can find out at least the cam info on both motors? The right cam and the KB167 pistons in the 318 would make me hands-down choose the 318 over the stock, low compression 360 with too big of a cam.
