13.3's to 11.8's to Forget it...

So, that big stack of time slips are all from that one hot combo you built?
The one you ran 11’s with?
If so, nice job!!

But.....if that stack is from various iterations where you pulled it apart to change things around...... I don’t consider that the same as running one combo for “season after season”.

When I had my roller cammed 448 in my heap running 10’s, that combo remained unchanged for 3 seasons of bracket racing.
A couple hundred passes........ no changes to anything.
(That was my attempt at running 10’s. Went 10.91 right off the trailer).

But, I still say that for the amount of 11-sec passes(well...... attempts at 11’s) 318will will make in a season...... a stock 360 short block in good condition would be “no problem” at the required power level for the target goal.
He’s going to change something around with it after a season anyway.
