Where did it make 434, and was that with open exhaust? Can you post the dyno sheet?


Ill post the dyno sheet tonight. Unfortuanetly my home computer blocks this site, so Ill post a photo of it later from my phone. Exhaust was open and do you mean at what RPM did it make that power?

When you or anyone has done one of these big cams are you addressing the OEM rocker bearing failure with one of these upgrade kits or using a aftermarket rocker?

Migs- When installing a cam, you definitely want to install a trunion kit. I would even install them in a stock application as the needle bearings have a tendency of coming out of the cages and destroying engines. There's a guy on the SS forum that had a relatively low mileage failure on a stock engine.

Whatever you do, don't get the Comp kit. There seems to be as many failures as installations. I would go with Straub, which gets rid of the needle bearings all together. CHE also makes a bushed kit, but it doesn't seem as nice as the Straub kit in my opinion. This is a big thread, but worth the read. The CHE kit is discussed near the end of the thread. Post #9 shows what happens with the Comp kits.

The stock rockers are actually very strong, so there's no need to replace them in most situations.

Does look good and just a slight cost increase to get rid of the bearings completely

Any idea why the giant drop off at 6500? Are you using a stock type MAF?

That's where it shifted. I had mentioned in the first post HPtuners would no longer lock the car in 4th gear. So that was a 3rd gear pull and the dip is tbe car shifting in to 4th
