LS1 Head/Cam package idea...

[Uncle Paul]

Just kind of testing the waters with this idea.
I have a set of heads that I am going to port/polish myself, then take the heads to a machine shop to have them decked, 5 angle valve job and flowed.
I will then assemble them with Comp Cams 978 dual valve springs (good to .650 lift), new valve stem seals and new steel retainers.
Along with the pair of heads I will be selling a custom grind cam (RPM-6) the specs are 242/248 .612/.615 114 lsa.
To give you an idea of the power that cam puts down:
Stock LS1
Stock heads
Long tubes
True Duals
Intake
Pulley
Ported TB/MAF
Automatic
8.8 Ford Rear end

It put down 347rwhp/365tq unlocked and that was on a Mustang Dyno. (Figure around 360-375 on a Dynojet)

That is pretty impressive for a cam only car!
Now add some better flowing heads to the mix, proper tuning and you have yourself a 400rwhp+ car easily. :D

I am planning on selling this head/cam package for $1500 (uninstalled, for installed price it will have to depend on the situation, parts needed and so on.)

I was wanting to know what you guys thought of that price. I think that is pretty reasonable. :D

Doesn't sound unreasonable at all to me.

I hate to be the one to knock something, but.....

For the size of that cam, I would hope it put down more than that. I put down 400 to the rear wheels w/cam only and decked heads(make up for piston valve reliefs, -4cc, forged motor). I have full bolt-ons and everything, but still. My cam has 12 degrees less intake and 16 degrees less exhaust, and only has ~600 lift on both sides.

Brandon runs a cam almost that same size in a 408, and it idles beautifully and puts down 470rwhp w/stock heads and an LS6 intake.


I think thats a real fair price for a setup, no doubt, but you may want to re-evaluate the cam choice, especially for a 346.

[Uncle Paul]

I agree, it didn't put down a huge number on his car but if you were to run that cam through a M6 with a stock rear end (which is considerably less weight than a Ford 8.8 inch rear) then 400rwhp is easily reachable on a cam only car. :D

The only reason that cam is part of the package is because it is the only cam I have that is currently sitting on the shelf.
I have a smaller one on the way, but that is going in the wife's car.

Ok I really want to do a H/C swap on my car, I haven't looked much into prices and etc...I would love to install myself as I have all the tools and the experience to do so. (former GM Tech) But I have no garage etc...If lets say when I get my tax return etc...and a little cash gathered up in the next couple months. If I buy a h/c setup would somebody be willing to help(provide garage) with install etc...I live in IL remember that.

If you were willing to make the drive to Nashville, I can rent out my time and space for ya. :D
I can even supply the spare guest room for ya.
Of course I will need to run you through a thorough background check first. :D

Just visiting here from 3rdgen.org, it's good to see that LS1 guys arguing about rear wheel dyno numbers is universal :wink:

[cyphur_traq]

lol.....no arguement here, just pointing something out.

rwhp is only one measurement of a cars potential/power fwiw, but since its the only one he posted its the only one i could comment about ;)

[Uncle Paul]

I have been tempted to stick that cam in the wife's car and throw it on the dyno to see what a cam only M6 car will put done with that cam.:idea:
But with her heavy foot, it probably wouldn't be a great idea.

If I come across another used cam though, I will definitely snag it.
That way I can offer more than one choice.
:D

All the bolt ons F11 cam through a 4.10's in a stock 10 bolt 408/390,. Alan Futral did the tune. It runs like stink and on Nitto's with my lame ass driving on a 1.9/2.0 60ft 12.3's/12.4's @116-117 mph. Just #'s

[Uncle Paul]

Those are some great numbers! :D

I was looking at the specs of the cam I posted and realized that I put up the wrong one.
That is the cam I have in Rally right now, the one on the shelf is a little different.
I want to say it is a 246/248 .615/.615 117LSA +0
It's a sleeper cam. :D
It was made for a cam only Nitrous car and I just realized that I do not have HP numbers for what he put down with this cam on the spray.
He did mention that the cam sounds completely stock though. Almost no lope compared to a stock cam. It was very "daily driver" friendly.
