Here's one of the threads I read recently http://speedtalk.com/forum/viewtopic.php?f=1&t=30927 It's got a lot of "opinion", but some legitimate experience talking as well. Here's one that has some discussion of the cams we are actually running and touches on dcr also. http://www.fullsizechevy.com/forum/g...-searched.html

So, I did get my base line power numbers on Friday. 147HP/232TQ, which is about what I was expecting. Using 30% drivetrain loss, which I think is pretty accurate, you get 210HP/331TQ at the crank.

Jeff, will you post a link to one of my videos?

Here's the one where it was spinning on the rollers, not sure how he did that but it surprised the crap outta me!

Well, I hope everyone here believes in better late than never. It's been WAY too long since I've updated this thread, but here it goes.

For the cam I ended up going with a roller cam pulled out of a Ramjet 350 crate engine. I think that I paid $50-60 shipped? I can't remember for sure as that was back in May. This cam specs 196 I/206 E @.050 adv duration with a 109 LSA and .431 I/.451 E lift w/1.5 rockers or .460 I/.481 E w/1.6's. I am running the stock 1.5 stamped steel rockers for now, but I'm planning on swapping to 1.6 full roller rockers as money allows, which won't be anytime soon.

Notice the tight LSA this cam has. The tight LSA builds torque quicker, and with the mild overall specs of the cam, won't make for too much overlap. Check out the dyno on the Ramjet 350 here: http://www.chevrolet.com/performance...m-jet-350.html This engine has plenty of grunt down low which I need, and also peaks HP around 5100-5200 RPM. After a ton of research and consulting my brother Jim (Compulsion2Mod), I decided it was a great budget cam for my project.

I realize that this cam won't make my engine a Ramjet 350, but I think it will still work great for my application. More to follow...

The long term goals for this engine now include TPI and a 411 computer swap, both of which I already have. I think the stock TPI system won't be quite enough to support my setup. This and the fact that I don't have all the parts, most importantly the harness, for the 411 swap, is forcing that part of the project to be postponed till a later date.

I decided to go ahead and swap the heads and cam, and I'll do the other parts whenever I can. Here are the pics:

If you have a lift and you're working on a truck or SUV, a great trick is to pull the wheels and lower it to the ground.



Intake, accessories, and water pump removed. I would've documented this process, but it's BORING and I'm sure everyone here has seen it/done it many times.



Yummy! Apparently this is why you should actually CHANGE YOUR OIL! It's crazy how gunked up this engine is/was. I got this engine in a free Suburban that I got from one of my sisters. I knew that none of the maintenance had been done, but she literally gave it to me running and driving with some gas in the tank. So the price was right and I swapped it in the K5.

I pulled the valve covers shortly after I installed it in my K5 and oil came pouring out. The reason you might ask? The drain back holes in the heads were so plugged up that the oil couldn't drain back to the pan!

While I was having fun scraping goop out of the lifter valley, Jim hooked me up with a fresh coat of Chevy Orange on the heads.

Also note the upgraded valve springs on these heads. I was fortunate to get these thrown in when I got them from Jim. It's hard to believe that this mild engine needs upgraded springs, but the stock units are only rated to 4,500 RPM and very low lift.
