Add 273's, 340's & 360's to the "318 Race" ?

Well, I threw out numbers that I think will be close on the 273, 340 and 360. I'm hoping the others will chime in and let me know their thoughts. Maybe .5 isn't enough for the 340? If you bore a 318 out .030 you get docked .4, so maybe a .5 isn't enough?? After all, 318's are noth'n, and everyone is told to get a 340 or 360... maybe there should be more of a difference ?? LOL

• Like last year, when it's all settled, I'll start a new thread with the first post being the penalty box, participants (we add as we go) and what is a "street car".

I think your close.
The reason you said you did .4 on an over bore 318 is mainly better pistons.

Id leave as is cant be to far off.
We see
Always can fine tune it next year.

Im not doubting your picks when I said I hope I get into 12 with 2.96. They do say these create engine are capable of low 12 with good gears. So a set of 4.10 - 4.30 would get me in low 12 both with your penalty box and reality. So I think your on the right track.
