Anybody ever swapped out a heavy( stock) rotating assy for lighter aftermarket?

Sounds to me like a piston swap for the stroker is a better option.
Get it down into pump gas territory, put in a cam that isn’t set on “kill”.
Makes for a nice low maintenance mid-range racer...... that can be used on the street with no worries.

I don’t see a lighter bobweight, with no other changes, doing much to lower the ET.

current 360 “ might” be 10 to 1. Its even that because i skinned the heads to 58cc and run an 028 gasket. All factory internals.
The 418 is zero deck flattops. Be roughly 12.7 to 1 with 58cc head.
The other factor is me. I know me... lol
If i swapped in that 418 i would go to a roller and likely Trick flows as well. Block is tubed already for a roller. It gets to “ where do you stop” been there, done that.
My current convertor is a little loose, cam is a couple sizes too big.
If i take this 360 out at the end of the season( will have raced it 4 years at that point) i can swap in an aftermarket flattop zero deck deal. Now i al closer to an actual 11.5/ 12 to 1. deal. Now the cam works way better, and so does the convertor.
I am positive those changes would easily get the car in the 10’s.... plenty enough to tickle me.
I have been fast in the past.... lol. Life changes.
Can sell the 418 and more than pay for the freshen/ upgrade and keep the heads i have( which still could be a good bit better)
Make any sense now?

bTW.... last two season, couple valve lashes and oil change. Zero other engine maintenance needed. Love it that way
