Low power/low vacuum

When I tear it all apart, I'll be borrowing a degree wheel and dial indicator to make sure it's correct.

Since the front cover's coming off, I'm going to put in a new harmonic balancer instead of the one with 250k miles that's currently installed. Any feedback on the Dayco Powerbond 'Premium' ($60) vs 'Street Performance' ($160) units?

Picked up the stock replacement balancer and a new motorcraft cam synchronizer. Had a conversation today with both the machine shop that did the work on the engine and COMP Cams. Both think I have the wrong cam somehow. Ugh...

Longer pushrods, low vacuum, low power, everything is pointing that way. It would not surprise me one bit if it was the wrong part in the right box.

Got the cam out.

Not only was it the wrong part number, but it's not even the right brand. Trick flow with a lot more duration. I bought it from Amazon. My guess is somebody returned it in the Comp box, and Amazon sold it as new rather than a warehouse deal. Complete insanity.

Good lord .585 lift on that cam and its for an ls. No wonder you need longer pushrods and your power sucked. The E303's are only .498 with 110 lobe separation. Just absolutely sucks someone screwed you over.

Really amazing it even ran as well as it did.

Funny it even fit really.

Amazon is taking care of it. I'm glad - not sure I would have believed my own story from their side.

I have had nothing but good experiences when having to return items on amazon.

Comp swears they don't produce cams for Trick Flow so the only explanation is a customer swapping the cam and sending it back to Amazon. Honestly, impressed at their packing job. I never had a hint that I was opening a box for the second time. Instructions, comp stickers, etc were totally clean and the cam looked mint. Frustrating, but at least Amazon is handling it at no cost to me

How's that correct cam working for ya? At some point I'm going to be looking into some power adders...

 

[Craig0320]

I know the new cam is in. I think there still is a few things to button up to get it running.

 

[fastpakr]

That's correct - the camshaft is slid into place, but I haven't had much time to work on it since.

Understandable... my Geo Tracker blew a head gasket in July of 2017, I've had the parts for over a year, a 2 weekend project (pull head first weekend, get head serviced and installed the next weekend) has taken about a year and a half... and I haven't even touched it other than doing a compression test...
