When to upgrade rod bolts?
« on: September 19, 2017 - 10:03:12 am »
When do you deem it necessary to upgrade rod bolts? An rpm level? A power level? Depends on stroke? Always replace them?

Asking in general sense, but my specific case is b-engine rods & crank.

'97 Ram 1500 Sport 4x4-Bright Red 318 magnum
'67 Belvedere II-Dark Blue 318 Auto, now owned by my brother
'73 Challenger Rallye-B5 318 Auto, had a 360 in it, SOLD :(
'42 Harley Davidson 42WLA-U.S. army green 45ci flathead
'71 Challenger R/T-B5 383 Auto, now 400 powered and rusty!

If your rebuilding the engine replace the bolts....Personally I polish way the parting line on the rods too.... But since I do it myself all it costs me is my time...

and use ones that may be stronger than you need, because you may increase
engine power in the future.
