      Have you had a conversation with the cam designer yet? I'd let that person guide you the most towards a compression that can work well. Tell them what heads, hp(block) limits you have, the main factors etc, and rely on them to guide you to the best combo. I'd bet most would suggest a compression in the high 9's, like 9.7, but few would recommend 10:1 or more.

      Pushing the compression up does improve the all around grunt, normal driving, and limits boost which can be good for the block.

      Most people calculate compression ratio from basic specs of their parts. That ends up with an error I hear, of easily half a point off. You can do that for the parts you have, and use those for the cam designer, and deciding on tweaks during the build. Such as the head gasket, quench, head shaving, block decking etc.

      Lets review what has happened with the so called internet experts I have dealt with over the years of failures with this motor. I'm not in a hurry to blame, but these are facts.

      1. New motor goes in, it leaks from the rear main. The rear main was not installed properly, and also the cam position sensor (Distributor gear eats its self immediately).
      2. Numerous rebuilds including aluminum head/cam combo purchased from a so called expert. This turns out to be a fail as the springs were not matched to the cam. As far as I'm concerned, this is an absolute fail, and no return business will go that way.

      My opinion: These internet experts reputation precedes them and they are not really putting the attention in to the smaller guy (me) builds that they should. I went to them as I expected things to be done properly. They were not.

      To answer your question. Making power requires higher compression. period. Yes you purchase a cam that bleeds off the required compression to use with pump gas. Yes, my builder has cam selection software (That's all the so called 'pro's use anyway). My preference is to use an OTS cam if there is a profile that fits my build closely.

      This is case closed. I have proven this to myself thru my own experiences.

      There is always a possibility I will get an 'I told you so', but I am the one betting money against it. No one else.

      We will all see what this motor makes for power on an engine dyno once complete. Yes there will be losses once its in my motor with a different intake manifold, but we also know there will be a huge pickup with boost added.

      that and the internet "experts" will most likely wipe their hands if something goes wrong. its always better if you can walk up to someone in a shop and say "this is what i need/want. what is out there.". it also better if its in person as well because if everything goes south, you get to go back to the guy, and drag him across the counter (yes, i have done that once). the guy that is doing dons motor, i recommended him to don because he has done some work for me, and i know others that have had work done by him and swear by him. i didnt know this, but there are a few speed shops here that send their motors to him as well. a couple of them were also in drag week (one guy if you want to google is sheldon root who was doing monster wheel stands in a chevy acadian)

      My motor is getting some love finally.
      Here's some pics of it getting the line bore done.
      Next is clearance for the larger hv pump and stroker clearance.
      Hopefully by the end of the weekend the bottom end is well on its way to completion.

      After the bottom end is done are you getting it back to install the top end?
      Do you think it will still be cold out when it ready for installation?

      How cold is cold up there? We're in the low 30's at night already, and highs may reach 50 most days. We only got about a week of Fall, it went from the upper 80's to the 50's that fast.

      Its cold here too, same thing, went from summer to winter with only about a week of Fall.
      Today is a high of 29, tomorrow is supposed to go up to 35.
      Not anywhere near as cold as it is in Canada though I'm sure.

      Dono, how cold is it there today?

      The motor is going to be completely assembled (oil pump, heads, rockers, valve covers...... )and dynoed by the builder before I take possession of it.

      I'll just need to do stuff like add the headers, and the efi intake before dropping it in. This way. we all know the motor is solid.

      I do have a garage that can be heated and be reasonably comfortable to work in. My wife will just have to park outside for a week or so (I don't want to rush anything as I'm getting old and lazy).

      The heads will still need to have the chambers re-worked, the bowls worked, and the ports smoothed using a flow bench. Then the cam will need to be matched to the heads/bore/stroke of the motor and ordered.

      It's just nice to see I'm finally in the front of the queue and getting some loving.

      edit: It has warmed up to about 26 degrees Fahrenheit. Its actually pretty warm right now. Unfortunately, that brought the wind with it. My garage is really well insulated. I do wish it had a heated floor though. I'm a suck when it comes to cold.

      i'm already bugging him that we WILL get the motor in no matter how cold it is outside. ive also told dono that if he hears noises coming from the garage in the middle of the night, it might just be me putting the motor in just to hear it run in the truck!

      Sorry Gman, I missed your post.
      I'm looking for around 450 to the wheels. A nice strong torque curve starting low in the rpm range is really what I want rather than peek hp.

      There are lots of reasons why I think this is actually a bit aggressive.

      End of the day, I just want a fun truck that isn't eating thrust bearings. As long as I have that trans cooler line pressure under control, I'm sure I will be ok. The hv oil pump will be added insurance. The machinist isn't concerned at all with making it fit. He's going to split the difference in height and mill half off the block, and half off the pump mount (Assuming there is enough meat on the pump mount). Then, make sure the pump feed hole matches perfectly. I think this is going to be more work than he is telling me. I'm just happy he's willing (and excited) to do it.

      I have to say, I'm excited to get everything together and see what the motor will do with that higher stall torque converter. Even though my other torque converter was a 2400 stall, I think it was just too tight. Hopefully this one nails it.

      Just thought of this, he has the oil pump drive shaft right? He’s going to have to do some machining on it to

      Yup, your right. He's already prepared to do that also. He's not absolutely sure it will need shortening as there's lots of play, but he is ready to do it if necessary. I'm betting that hardened shaft wont be easy to shorten.

      450 sounds like a great healthy number. Should take daily abuse, erm.... use, for a long time.

      Who knows, he might have it done by the end of next week. Was going to also say, I’m off during the week of Christmas, if your not heading to saskscratchyourass, I can give you a hand without any problems

      I love the pictures, that's eye candy for gear heads.

      For the power to be a lower range than top end, have you sized the turbo on the smaller side? That adjustment can help a lot, choosing a turbo that begins to run out of breath before the shift, and spools up quicker in the low rpm's.

      Yup, turbo is smallish and runs out of breath early. That will give my more boost down low.

      Tim, I'll be heading to Regina to visit my family.

      Interestingly enough, Regina stands for 'Queen'
      Regina also just happens to rhyme with ??gina.

      And.....Instant HV oil pump!
      Checking the pump drive will have to wait till the Cam Position sensor (Or a distributor) goes on.
