Crower 272/272 Cams, Prothane Mounts, and Balance Delete... How bad vibration???

Anarchology · 10-06-2008, 01:15 AM

I saw an ad off of this site pointing to a damn good price on some Crower 272 cams ($350). I can't beat that price, and probably going to take that up. As it sits, the engine is out of the car and ready to slap it in in minutes, since I'm in my garage right now.

I have a set of Prothane Motor/Trans Mounts going into the car either way, and I deleted the balance shaft after the front one ate the bearing giving me a bunch of hell. I understand that deleting the balance shaft adds some vibration, and I would figure that the Prothane Mounts would only intensify it.

I'm contemplating buying the Crower Cams RIGHT NOW... as in minutes from now. I'm wondering how bad of vibration am I going to expect. Now, I'm not a novice when it comes to cammed cars. I've owned a couple 350 3rd Gen and LT1 cammed F-Bodies. A little car shaking isn't much of an issue for me.

So my question is... am I looking at tolerable but somewhat noticeable vibration, or teeth chattering shaking from this setup????

I have 264s on a 2.3 stroker with balance delete and prothane mounts. It vibrates but its not excessive. At low RPMs the car vibrates a little bit but at around 1100 it settles out. Your still going to have that mandatory "where is that coming from" interior rattle.

Thanks man. That is what I was looking for. I'm used to that feeling in the f-bodies, so the Talon shouldn't surprise me all too much. I was just wondering if it was some kind of unbearable vibration that would make me go insane.

Just ordered the Crower Cams and they will be on on their way very shortly. Can't wait to rock my project with some power and a good sound... for a 4-banger, that is!

Ya it sounds pretty mean. The virbations arent unbearable, but you will notice it after a long drive when you step out. But to me it was almost the same as before i built my motor because it vibrated also. Hope this helps and good luck on the build!
