Hey! Long time 1FastBrick! Good to hear from you. That's true man. I probably need to actually make a build thread too. I hope to get an update video on the Camaro this week.

Haha Yea, I haven't been on tech enough lately. On this thread, I've just been watching the show.

 

Well so I did a cam swap this weekend and put in a cam Rob specd for me. Specs are 230/250 117. The old cam was a 218/239 115 (for sale btw).

Interestingly the new one seems to be more stable and easier to tune. It wants a lot more air at idle, which is nice because it means my screaming TB isn't as loud any more since I can open the set screw. The mid range feels much stronger with no loss of low end. I haven't really revved it to see how the high end responds but I anticipate much better.

Fueling is interesting. It wants less fuel in the low end, which is what I expected, and some in the mid range, but under boost at any rpm it wants more fuel. That one caught me off guard a little bit. Overall I am very happy with the swap and cant wait to test it out. I am taking it gingerly to see how the pinned waterpump holds up.

 

Glad to hear your setup likes the new cam

 

As you start to lean on it harder the difference will only become bigger!

 

Im not sure if I said it clearly, but overall this cam drives smoother and the engine just seems more comfortable overall, which surprised me because it is a good bit larger than the one it replaced.

I measured the IW OD crank pulley two different ways and came to a minimum diameter (bottom of the grooves on the ribs) of 7.90". I also measured the stock truck pulley as 7.240". So hopefully if someone really needs the measurement here it is

 

Atomic, I been keeping up with your build. Really good info for us dumb dumb. Thanks

 

I wanna hear this new cam.

 

New cam video while I was getting gas


The guy at the place where I got the firewood complimented it haha. I had to do a bunch of 3 point turns and it didnt stall once, so I am pretty happy about that. Idle rpm is about 850rpm.

Current exhaust setup is speed engineering 1 3/4 headers, homemade dual 3" to 4" y pipe, and big diesel type flo-pro 4" muffler to a 4" tailpipe.

Not really happy with the exhaust, just doesnt sound that good. Whenever I save up enough for the ARH 2" headers I want to redo the whole thing and put dual 3.5" cutouts off the header collectors and run dual 2.5" or something back to stock muffler.

 

Sounds great!

 

Sounds like it is idling very nice! I'm curious to see some times out of this thing now. My cam sounds dang near stock. I hope it performs half as good as your old setup. I can't wait for summer up here to finally get some high boost numbers out of mine.

I think it would be awesome to try different setups on the same motor.
