So if you want a small lift cam and mild springs you maybe able to keep your AFM lifters... Never seen it actually done.

So DoD is the technology, the AFM lifter is how that technology "works".

Thanks for that information. I did not know that. I am also getting ready to change out my cam. I am going with a kit from Jannetty Racing. I would like to do the work myself, since I do not trust anyone in Las Vegas, but i have yet to find a step by step process. So looks like I am taking it out of state for the work.

I do have another question regarding camshaft work on the LT1.


One shop says they need to drop the motor to install the camshaft properly





What's the truth behind that?

Not properly, just easier.... while many people have done it without dropping the engine... you'll find shops prefer taking the engine out.

I changed two cams now from the front....

Makes perfect sense if you’re also upgrading to forged internals.

I have 2 packages i'm comparing from different companies.
- CAI, TB, Cam, Headers, install, tune = $8,750 ish


That's starting to come in at about $90/hp... does that sound accurate?

[Umbriel]

I paid:

$1200 for headers and CAI
$2600 for cam kit and converter
$2500 for intall
$700 for tune

That got me right around 100 rwhp. Car ran 11.2 in the heat and 2000 DA.

Doesn't that put you right in the ballpark of a supercharger? Why even open the motor. Bolt the charger on and go

[oldman]

For me it is a hobby, all the labor =$free. I liked going FBO to heads, cam, base supercharger => forged engine D1X supercharger. I'll tell you straight off my mid level build far exceded any ability to hook that to the ground on any tire less than a drag radial 00 wear...

Basically did the cam for the 32% fuel lobe so when I supercharge it I will have enough fuel. I have already put a supercharger on it.

I love working on my car... I did everything myself... even the blower (this with a friend) but heads and cam... it's just too far out my league... If I had some guide, I would do it, but not comfortable enough by myself. If not I would've been H/C a long time ago... just hurts so much money on labor and me being as picky as I am... I would only trust one guy to touch it and he's in NC so besides labor.... shipping fees too... so literally I'd be spending more on getting the H/C installed than actually the kit itself.

[oldman]

yep now that I'm retired. I was thinking of going into business something like "your dad's help". I would showup at your house for $50 bucks an hour (I'm cheap and slow)... LOL and do whatever project you wanted me to "help" with. I would not do a project on my own, I would only do projects that I know well: 440 Mopar, 340 Mopar, SB Chevy, Integra, K20 Civic, and Mini S. Could do just about everything. Or B, take the cushy retirement and to Colorado and .....

I am in the same boat. I do all the work on my car. The cam is a bit out of my league, unless there are detailed instructions on how to, then i am game. There is no one, in Las Vegas, that I trust and the only shop in Calif, does not so installs anymore. Yes this is VERY CRAZY, but I might be willing to ship my car to Jannetty Racing.
