Are you sure there 2.92 gears?
What size tire?
What’s the goal?
Spirited driver?

Yes, almost 100%. I just asked again on the Aussie FB page to confirm and unless my Chargers been optioned thats what it will have. Is that an unusual ratio in the US?
Im not home to look at tyre size, 15" anyway.
The goal is to put under $1000 into this engine in as short a time frame as I can, get it installed before the summer and the new baby comes along. :O A goal I do have in mind is lots of fun and also when the 340 is rebuilt have a nice motor to sell to off-set the cost of the 340 Build. So when I do come to sell, and as previously mentioned if Im having lots of fun with this 360 then the 340 might get pushed further down the road, but estmates on figures would help the sale I think? Not so many 360's or 340's for that matter in the UK.

The KB-107 @ zero deck and a .040 gasket will come in at (or right close to a) 9.8-1 ratio. A small cam can cause detonation issues. A thicker head gasket may have to be employed or skip the block decking to zero.

A dome piston will make matters worse.

Those KB-107's look perfect if I bother going down that road. What are you considering a small Cam here? Would the 340 one be OK? Or maybe a Comp Cams 274H would maybe be better?
