if i were here and this far in i would definitely be doing the cobra engineering mod for the tensioner.
Thank you for the input. I did talk to my tuner and he said comp stage 3's won't be a problem so I'm taking his word for it. A few years ago I did comp stage 3 cams on my 2v and with a tune it drove good. Now I just need to decide if I'm going to need a low pressure bypass valve for the Whipple or just stick with the stock one. My tuner is very good.^^Good advice on the passenger side secondary tensioner. It helps maintain timing accuracy while the engine is running. Also, you can get better accuracy with an 18" degree wheel. https://www.summitracing.com/int/parts/mor-62191 although I don't know how feasible that is with the engine in the car.
The cams you listed have a lot of duration. The idle will sound awesome but be prepeared for driveability issues below 2000 RPM (bucking, stumbling, stalling) and high IAT2 temps when driving in city traffic. They say a good tuner can mitigate some of those issues. I recently swapped from Crower Stage 4 cams (236/244 duration) down to stage 2 (222/222 duration) because I was tired of the issues and didn't have access to a local tuner to help deal with it. Now it drives perfect with the help of an tune by Kevin Dunn!
That's good to hear. Thanks for chiming in. I'll have more updates this weekend. I'm ordering the cobra engineering tensioner this morning.I just tested my bypass, for different reasons, and I remember by 5lbs mine was open. Not fully open but enough to be effective. Hopefully that's the case for you
Once everything is moved out of the way it's not that bad.I give you major props for doing that in the car. It looks really crowded.
This exact picture is what I used to set up everything. They key is it shows enough room to get the dial indicator. Thanks! I'm all set up and ready to start rotating the engine and get some numbers.You can definitely do it in the engine bay. It's just a PITA. I always prefer to do it on the engine stand when possible but when I was working out some annoying issues with various cam degrees I re-did mine in the car every few days till I figured out what I needed to and had them running properly. You have to tear off a bunch of stuff but after doing it a few times this is a one day job.
I think it's a hard process to learn in the engine bay if its your first time doing it but it can be done. Look for consistency. If you pull the chains off and put them back and re-check they should still be degreed spot on. If not you have some error somewhere in your process.

Comp cams stage 3. I was going to install them according to what is speced on the cards. I'm open to opinions on that.As usual Ed has some great info on degreeing with adjustable cam gears.

What are the cam specs? Now's a good time to study where to set the cams so you don't end up hating your car.
