Some M1 porting pictures and flow numbers

A big thanks and no worries, this forum and every MoPar brother out there always needs a little more information on their engine. There’s just not enough information out there to truly make the best choice possible and if you can’t get the exact part due to them not being made or being just plain old expensive, you just don’t know where you stand. It’s hard to make an informative choice when there’s no information.

Having the intake test before and after porting was a good chapter on the MoPar M1 single plane we all needed and I had zero issues with waiting on it in any way shape or form since like everyone else, I wondered and had to know.

As a final note, I had the amazing and crazy weird luck of being fortunate of not only meeting & breaking bread with @George Jets but also being introduced to another friend of his where we hit it off awesomely at the MoPars of Breavare (MOB) county car show and swap meet.

I met Charlie Servidio (Say, Sir-Video) who some may know from this forum as doing R&D work for David Vizard and the “Mission Impossible” 318 build. We are now hanging out playing with cylinder heads and flow testing them and intake manifolds. So stay tuned to my YouTube channel as well as Charlie’s YouTube channel. You’ll get the best meat and potatoes from Charlie’s channel.

As a final word, don’t race flow benches, just use the before and after results to help better understand what’s going on.

Stay tuned to Pittsburghracer and his work.


John, thanks again. On behalf of this forum and MoPar brothers out there, this information was sorely needed because it was missing.
