I am preparing to do a cam/timing chain and custom computer with program to run to 7000 rpm I will shift at 6800 I am also installing a LS6 intake egr delete 2001 LT headers. I am upgrading the rod bolts on the bottem to prevent one from coming loose. I was wondering who else has done this upgrade I would like to run the cats to do my part to protect the OZONE but if not I could ditch them for 15HP end result a streetable low 12s high 11s My question is am I overlooking something. I will be running Mobil 1 5w30 for oil. This operation will begin early winter and be completed March so I have a little time. Thanks

Sounds good, but why the rod bolts? I have heard no bad news about our rods coming loose. The only week link in our bottom end is the coke can pistons. If you plan on running it up to 7000 rpms which means if you miss a shift well over 7000 you might want to consider new springs,retainers, and some hardened rods. This is just what I would do if it was my car and my money. Other than that it sounds like a very medium setup. I have seen alot more radical setups that are still streetable. Have you considered getting the heads ported, or atleast the intake and exhaust ports matched?

Well whatever you do it will be a good fun time. Good luck....

Just remember you have some serious traction so you might want to get on the STAR purchase:0 I know that when I get my traction issue resolved I will be breaking something....... Just a thought

If you're gonna dive into the lower end, definately get some new pistons. ...ARE is having a GP right now I think. And...since you have the heads off, you might as well have them milled .060 to raise the compression to around 11.0:1.

Also if you're gonna spin that high, I'd invest about $150 in a ported / polished oil pump. ARE and MMS seem to be having the best ones out there so far.

As far as the timing chain, I'd go with the Cloyes gears and a Jwis chain. It is a really good combo, and for the money you're spending it would be a wise investment. KaTech has the best price on the chain and gears.

Sounds like a pretty nice set-up, just take your time and do the research and make sure you have the right parts the first time. Anyone can put a bunch of pieces together, but putting the "right" pieces together is the key

Tony is going through Katech cloyes timing chain is the one they reccomended. I am getting stage II heads but thinking about stage III w 2.08/1.60 SS valves and no CC 941 springs he told me they would be OK I would rather spend extra on the head work rather than change them every year. It is a $600 difference between the two and 20hp. I will be putting studs in the block to hold the heads in place. So if I blow the cookies out of this one. I will have the stuff to build at least a 382 stroker. I would rather wait on the pistons I have 15000 miles on the car. I am on the lookout for a clutch for a spare .I could run what I have until it is dialed in giving me a known cheap weak link I am not ready to do the rearend. It was reccomended to use the new rod bolts when turning 6600+ to prevent a rod bearings from spinning. I also like the Idea about the oil pump.Thanks!!! A solid belt tensioner is also on order. I already blew 1 belt and was also reccomended at these RPM's. This is a complete tested kit running consistant low 11's high 10s. I am setting my goals kinda low and raise them later. Price for this kit is about $5000 for parts only seems steep but It is complete and running 480-520 HP. The cam is also a custom grind.

The Cloyes chain is just a stock chain, the only thing different about their setup are the gears. Get the Jwis chain from KaTech...it's well worth the extra few bucks.

Other than that, sounds really nice.

Thanks I will do that. What about heads II or III I must be able to drive 400 miles at a time. I plan on keeping 3.42 for now. When I upgrade the rear it will be 3.73.

I'd go with stage 2 heads... the stage 3 heads are designed for larger displacement (primarily bored) motors. On a stock displacement motor the larger valves in the stage 3 heads are going to be shrouded. Spend the money on some other mods

FWIW, I have a set of Cartek Stage 2 heads on the way

You are wasting your time and money by going from 3.42 to 3.73 gears, there is not that much difference. If you're going to do gears I'd definately recommend 4.10s and it really won't hurt your gas mileage that much...a couple MPGs.

Are you going LS1 or LS6 cartech heads? I guess great minds think alike. I am required to take 7 hour trips on the bahn to visit the inlaws this is the logic behind the 3.42 gears. Are you doing the LS6 intake?

They are LS6 castings. The 3.42s really are not bad gears, my point is that if you are going to swap them out, go steeper than 3.73s. There is not enough difference from 3.42 to 3.73 gears in my opinion to make it worth the cost. 4.10 will make a much bigger improvement and like I said, will only be a few hundred RPMs higher at cruising speed.

With 3.42 gears 80 MPH is at 1800 RPMs, with 3.73 gears 80 MPH is at 1950 RPMs and with 4.10 gears 80 is at 2150 RPMs. As you can see there is only 350 RPM difference from 3.42 to 4.10 gears at 80 MPH. Obviously this is only a "snapshot" of the change though.

Here is a gear ratio calculator for you to plug your own numbers in to.

Thanks and it makes since. I will get through this engine pump up, and I am sure this viscous will continue. Are you doing a complete kit or one piece at a time? Originally I was going with just a cam/springs pushrod package (then I started checking springs and got nervous thanks to you. I will be running a large cam and I do not want to blow springs. Now I am up to a complete top rebuild. Oh well I am having fun and I plan on bagging a 396 next spring when he has it dialed in that TOY thing sounds nasty.LOL

You "may" bag a 396. Sounds like you just wanna be Top Dawg. Well stand in line because there is a bigger fish
on the horizon.....
S/C 383 650+rwhp demon.........

And lets not forget little ole me. 396 w/ the strange
whine to it........she won't be NA for long if you keep
messin w/ me..........T-76
May no longer be a Top dawg thang but a whose got the deeper pockets thang...........

Damn John... I just got done doing a waterpump tonight .. Is yours going out also? LOL.....J/K See you tomorrow for the cam install..... Should be fun...

you want some cheese with that wine?

Sorry, I guess it was a differant wine.

anymore of this, and I will break out my top secret icon!!!!

I am making my own kit I did some pretty thorough research and spent numerous hours on the phone talking to the smart guys and running desktop dyno numbers, researching cams and heads, etc. I finally came up with my "ultimate" set-up within my (the wifes) budget.

I am doing most of the work myself to further save money to buy more parts

Glad I made you aware of the springs deal before you made a costly mistake. I know too many people here in NC that have blown alot of money repairing the damage caused by broken 941 springs.

I am a firm believer in spending a few extra bucks (oil pump, timing chain, etc)to save you lots of bucks (rebuilding motor) later.

Good luck with the cam install this weekend. I will be at Rockingham most of the weekend, but if you need some advice or online help, just let me know.

Thanks Jamey I am sure it will go ok... The damn crank pulley is all I am worried about... and maybe the lifters falling... I bought all new gaskets and a crank bolt.. I will have all the right tools so I will not be ghettoing it...... I will let you know how it went........

The lifters are not a problem, just make sure you spin you cam a few times before pulling it!!!

I didn't use anything to hold mine up...I pulled my old cam and slid the new one in RIGHT after. I was kind of worried too

The pulley was really easy, I used a 3 arm 4 inch puller. I bought a 6 inch one first, but it was too big to fit, so I bought the smaller one.

I also got my spring compressor from Sears (Craftsman) for $16.00 and it worked perfectly even on #8. No clearance issues or anything.

I must have been daydreaming, cuz I didnt realize you were going to do a cam. Outstanding man, and I hope it goes great. Now maybe those LT1's wont pick on you...J/K

Damn Jamey, whats next? about a .90 overbore with 16:1 pistons spinning to 10K?

Hope everything comes up roses. And if your going to Rockingham to run, the kick azz!!!!!!!!!

later guys
Rob

hmmmmmmm....that's not a bad idea!!!
Actually have some pistons on the way too

What's next?
- Hal Shocks
- 9 Bolt with 4.11s
- and something with a strange whine (notice no headers) (and no George, my water pump is just fine )



I hope so too
I'm shooting to break into the 11's. I removed the rear seats, spare tire/jack & front sway bar. I'll also be running skinnies and 10.5 inch slicks. Wish my rear end (both of them(if I break one my wife will kick the other )) good luck.

I am just playing it is not about being top dawg, It is thinking you are. I am sure there are people out there that want to bag the Hawk. It is all fun for me and if I get set back then I asked for it by talking smack. Who has the 383 with a bad waterpump? is he registerd yet? As far as deep pockets go I am pullin fuzz right now. John you should put a hurtin on me with what you got once you get it dialed in. I think LOL
