Ive done research on this board for a while noe and im going to go with an f13 cam. So far im going to get a ls6 ported and polished oil pump, ls2 timming chain, ls6 intake, ported tb, tr55 plugs, and new wires but not sure which ones. Im also getting full exhaust, gmmg, lt's, ory. The one thing i am having some problems with is springs for the cam. I am an every day driver so i most likely have to go duals. Im wondering if these will work http://www.jegs.com/cgi-bin/ncommerc...58&prmenbr=361

Also what length rods should i go with 7.400's? Ive heard i should be fine with the stock rockers with maybe a bearing mod. Also titanium retainers. And after everything is all said and done a tune. Will i be ok with this? my car has 13000 miles on it so i dont think ill need lifters or anything. Im gonna save up some money and ease on launches wen i go to the track every once and a while till i can get a 12 bolt or 9'' with some mt streets or so. How prepared do you think ill be with this list?

you want 7.400 pushrods unless you get milled heads or a cam with a smaller centerline. You would be ok with stock length but you could get some aftermarket pushrods that are 7.400's. That will work with the FM13.

That sounds like you got just about everything you need. Don't worry about the lifters, they can handle it. I have heard some horror stories about the Comp R lifters. You would have to pull the heads off the motor, and it looks to me like you were not planning on doing this.

Double springs would be a good choice for this cam as far as insurance goes.
Comp 921's or Patriot Golds.

Are those springs ok though? And just buy retainers the same diam. ?

Most of the time you can get a packaged deal if you get it all through one company or sponsor.

well im buying stuff here and there for people that dont need this and that. All im missing right now is the cam, springs and retainers. I think i found some nice 7.4 hardened rods for 80$

That is a good price. You might be able to find that cam on the boards used as well. Place a want add. That is the way to do it!

so you think those springs that i posted the link above will be adequete?

yeah the dual ones go to .650 lift, which is great for a cam that is near .600 realisticly.
your good bro. Make sure that you get some TI retainers though for sure. Lighten your valvetrain at the same time as helping to prevent spring issues in the future.

FUN LS1

Just about any dual springs should be adequate, if you're going to change them every 20,000 miles, like you're supposed to. The lift on that cam is .595/.585, so those .650-lift Crane springs are going to be OK. One thing you might ask about is noise. Some springs have a reputation for turning your LS1 into a sewing machine, but I don't know about the Cranes.

Yea i am going to but im not sure what size retainers to get for those springs. what do you think just a 1.275 size retainer? and what about the seats?

If you order through Jegs, they can probably tell you. personally i would get springs and retainers through Thunder Racing. But that is just me

i think i may go with a set of manley springs from them part number 131-221426-16 and the matching titanium retainers because the comp cam 921 kit is way to expensive.

FUN LS1

Sounds good. Those are the springs Futral packages in their Dual Spring upgrade for the Cam kit. And I'm hip on the 921s, man, way too expensive!

should i also get a 160 thermostat?

orangeapeel

iTrader: (18)

I know, I stuck with 918's. But we will see when i am forced to get the duals.

Thermostat = yes.
Anythin while you are in there replace. Water pump if you got the bling for an electric one.

But i have heard that by making your car run as cool as a 160 thermo. your not leating the oil get hot enough to boil away any moisture in it. Isnt this true and depleat the life of your motor?

If you plan on getting a tune they can set it for whatever you want according to what you have installed, that will just allow you to go that low. I bet it will be around 180-185.

Anyone else have ideas?

I was also thinking about getting the rocker arm mod done by harland and nasty for my stock rockers. Would do you think?

OK, I have the F13 with the manley spring kit. First, the Manley kit will work fine and its a good spring kit. PRC, Patriot, etc are also good springs. Now, I recommend checking installed height with the manleys because I chose to shim them. You may need to as well.

As for pushrods, if you have stock heads/gaskets/rocker arms I recommend 7.425" pushrods, which is what I am using. 7.400" pushrods will do the job though.
