Simon

I'd like to see those ingots

Are they enough for the 408. I am interested.

I'm leaning towards some Dart Pro 1 225cc with 62cc chambers. I should be around 11.7 cr A cam grind of 232/236 595/602 114 1.75:1 Pro-Magnum Rocker Arm Kit with 5/16" Flat guide plates Pro Magnum Hydraulic Roller Lifters Hi-Tech™ Pushrods 7.4" x 5/16" Spoke to Dart today, great sevice. They told me their head is good for .625 lift and would be a great choice for the 408 (0.030). I'm just not sure I want to leave a sinble Beehive spring on. What do you guys think?

Comp Cams has some great service so far. Spoke to them twice today and they gave me answers. Can't say that about others i've been trying to reach for a week now... Their cam help line is very nice and their warranty managers very comprehensive. A++

I was very surprised by a mazdaspeed 6 once. They are AWD! with 270 hp. Nonetheless, I ran with one at the track and you better have a good reaction time if you want to be faster. I was faster.

0-60 in 4.68 secs isn't that something!!!

I have no problem idling or driving in traffic with my Yank 3000. Actually, you gotta run about 100 miles before everything gets in place but after that I just let go the brake and start moving forward. It depends how bad the traffic is...hell if my yank stalls at 3400 behind the 408 it's even better (plenty for me). It's also good to know that a low CR 408 feels faster than a supercharged 364! I will know around jan 7 if i'll be ok with the 0.030 bore and start picking parts from there. It's kinda hard to build a motor between Christmas and New Year's but gives me time to think about the setup which is nice. I didn't know that I could go that high with the compression ratio 12.2:1 that's alot! Quik, how was your gas mileage with you 244/248 combo and 11.1 cr? I was also considering a set of Dart heads.

The damage in the cylinder :

Just did...after

I never thought I'd see this

Here is what the cylinder looks like, only one got damaged. Their only high compression kits are for a 4.005, 4.030 and 4.125 bore. I just wanted to go bigger because of the scratch but how much you guys think i'll need. I know it's not easy to see but I gotta know before I purchase. My idea was to have the biggest bore in hand before I take it to the machine shop so we can clear that mark for good.

ok...I knew there had to be something lol it seemed too easy. I gotta know before I buy my kit... how much oversize max can we do with the LQ9 block??? I was just about to order the rotating assembly, it should be here within 7 days...

We are getting somewhere, I think this is what i'll do (same cam, same stall) but I will bore it at 4.125 because my ring cylinder is quite damaged and I don't want to have surprises when boring at only 0.030. I could always throw my TBTC which still layin' around in my garage but even then I think my Yank is way better than my jobber TBTC. 2bseen got a setup similar and runs 12.14 from his sig as quoted by him : "Well right or wrong this is the cam I got for my 408. Comp xer 230/234 595/601 114. I had my shift points at 6300 with the old motor and will be alittle higher we this one. I am running 2.05/1.60 valves with 10.8 to 1 compression. 2003 Chevy SS blue with a few other colors 11.49 at 117.29 mph Old setup/ New motor 12.14 n/a at 109mph. Showing hemis the tailgate soon. Check the vin its a 6.0." Still gotta decide on heads though.

Krambo, it is a shop that will build the engine but I want to keep control over the parts that will be in there because so little people know that much about the SSS. Just to give an idea, I find my truck a bit unideal for DD BUT I don't really have a choice since I practically have some engine damage. I just find it money wise to go 408 since I have to do all this anyway. The stall is going to stay in there until the new tranny failure that is for sure, a new cam isn't out of the question but I have so many thing that broke that I have to be careful not to blow "the budget" . BTW Eagle pruducts has a nice application page for their kits : Eagle Rotating Assemblies To go for a 11:1 ratio would only require to have 68CC LS6 "Style" heads from Patriot 2035 Assy. 2.08"/1.60"/68cc I thought that the 408 had more torque on the bottom end than the 6.0 is that right? Still wondering why i'd have to go higher on the stall. It just gets on my nerves sometimes...

Nice, 7 replies in couple hours...keep them coming. Are you saying I should lower my stall or have a bigger one?

After doing some reading about the 408 I decided to go that route. The truck is my DD so I need it to be quiet and fast. I will stay N/A for now but MAYBE go with a bit of N2O later on. I'd like to see some low 13's, high 12's. I've decided to go with the Eagle kit, new heads, new rockers, new lifters, new pushrods, same cam, same stall. I'm kinda new to this engine building thing but here is what I thought: Eagle kit 4.030 bore stroke 4.000" -2cc flat top pistons. Patriot Stage III heads 2019 Assy 2.08"/1.60"/72cc for a CR of 10.6 Injectors don't know the size in line fuel pump bigger oil pump double roller timing chain I'm very open to suggestions especially about heads or anything. Thanks.

That looks to me like a SRT-10 but couple years later... they should have keep up with dodge at the same time, makes me feel retarded.

You shouldn't have any problems selling that truck. Just clean it good price it right and place an add in truck trader. The fully loaded will help you alot.

Gee, how come I was sold that at the same moment than my cam with 591??? edit, I just found they are rated at .600 lift max, quite close to what I have

Hey guys I think it's time for me to say it's Simon lol

If i knew before, i would have changed them...look at me now!

Yes I have a blue stripe on them... About the motor, it's gotta be more powerful for sure but it is still my DD so I don't know if 408 is too much. Is 383 possible? I guess anything is since i'll be doing oversize and can buy the pistons for it... and maybe rods...if they are bent...

Just came back, it is a spring that broke and the valve is broken in two and all the parts are stuck in the head...the piston has the side of the valve nailed in and the cylinder is marked pretty bad. I think I'll need to oversize but don't know how much. how much oversize is needed for a 370 and for a 408 and what kind of piston or overhauled stuff I need?

Thanks for your support guys! I heard that there would be a recall from Comp Cam is that possible? I know now that it is from the top we'll se as the covers are removed...

Well, I was going to an appointment this morning when I suddenly hear a loud bang from the motor. I realize that I lost about 75% of the power and the big bang is occcuring at every rotation of the motor. Still don't know what it could be...I made a search but came up with nothing similar. Had the truck towed. To start the motor back, I needed to give close to full throttle to get it going and then it would die and not idle. All that with the great bang. I was thinking it would be a valve that fell in the cylinder but i'm not sure anymore. I think it's more from the bottom... Does anyone know what's happening?
