More Mods, More Help, More Posts from Luerja....Supercharger time
How can i find out what cam I have? I have been trying to figure out exactly what i have as far as the engine goes. I do know it is a GM crate moter built in mexico and have the part numbers and have identified the intake, heads and block but thats about it.
And if i don't have enough to do on the car, I now have the Install of a B&M 144 Supercharger so it is important to find out what Pistons and cam i have before i find out the hard way. I know if i pull one of the heads and drop the pan I can see what pistons I have but is there a way to tell the cam specs?
I did get a hold of GM and they could not find the build records for my engine.....Then i asked him if they had had the build records for my 72 convertible and he laughed.
Thanks in advance for all the help.... I'm sure this is not my last post on this install
If anyone can make it over here who knows how to set these things up I am willing to cook live Dungeness Crab, Steak, Maine Lobster, You name it you got it….I just need some expertise help before I pull a MsVetteMan on my engine…. ( just Kidding MsVetteMan)
I think I just really need help to do this right… Oh ya there is beer here too…
Posting a thread is like fishing.... you throw your lure there and watch watch it go down to the bottom and have to real it up again.... (no pun on my name there)
But this is a two part question here folks....I am am not going to make you eat my fresh Dungeness Crab and drink some beer but.... first question is how can i find out my cam specs and pistons.... I have done some reading and there is a number stamped on the piston........Bottom if it is after market and top if its factory....Right?
My perfectly running car will be down as soon as i take off the heads to i get this blower on but if the specs of the engine don't match up then i have to pull the motor and redo the engine.....but engine specs are not my specialty and need some help here..
Jim-Is this the $1200 Goodwrench engine special you have? I have owned these motors before, and the cam was first thing I pulled. Also if your going to run a supercharger, you're not going to want the heads or pistons either, so there's no need to waste time checking specs on them. The block and crank should be OK depending on the mileage, but hopefully someone wiser on the subject of supercharging will speak up
I'm just over the bridge(San Mateo/Hayward), so if you need help I'll see what I can arrange

No this is sapose to be some (383 something), (fastburn heads), (dual plane intake) $4995.00 motor purchased back in 2004.
So who knows?... it has excellent low end torque and a very nice sounding engine.
Is that carb supposed to be a doubl pumper. What did you do to it? You have two metering blocks on one side.
I'd venture that the item in question is a fuel bowl extension. The carb is clearly not a double pumper, thus the vacuum controller for the secondaries.

...and NONE on the other!?!
That is a vacuum secondary carb originaly so it is a single pumper. Look for the numbers stamped into the choke horn and it can be identified as to what is was originaly. Not sure what it is now.

How does it run at WOT?
-Mark.
It runs like a scalded dog out of a hole....lol
But the carb didn't come with the engine...so no big deal there.... I have a Holley 700 Blower Carb with the B&M 144 so that will be replaced.
Man, if you can't find the specs on your 2004 Goodwrench, I can forget finding out anything on my '96 Goodwrench
Nice engine though and even nicer plans!
Dou you know if your drivetrain and such are up for the blowers power?
I have new trailing arms and fresh rebuilt Rear hub assemblies from Van Steel. New u-joints on the half shafts and that’s all i know so far. The clutch is good but I think that may have to be replaced a better one down the road with this new found power but I don't plan on abusing this car all that much.
That blower intake will not work on the 383 in that picture. The engine pictured has Fast burn heads, notice there is only 8 bolts that holds the intake on. Different bolt pattern. You either have to go back to a conventional head or try to find a blower intake with the vortec port and bolt pattern. Weiand makes one, not sure if it will work with your old blower though.

Thanks, I already have the part on order. My B&M 144 is the same as the Weiand 142 so parts and gaskets will be interchangable.
I just need to make sure I don't have too much compression and the correct cam and pistons so it all plays nicely together.

Just listen for a ping, then you'll know.
My aftermarket pistons have part numbers stamped on the bottom, with the oil pan off they're easy to see. Don't know where the numbers are on GM pistons.
As for the cam I don't know what to tell you... You might be able to measure actual lift with a micrometer but there is still no way to measure lobe separation or duration.
And you can always look for a part number and google it. But then again, why waste the time? Cams are only a few hundred bucks and you know that with a more suitable cam you'll make much more power. The odds of this cam working perfectly in a blower app. are slim to none.
Also, if the compression is too high, this stuff might help. My friend uses it on his blown 625hp 95 Cobra.
