Sorry, I should have added the following: I purchased their W2 Econo setup, which included the shafts, they are 3/8".
They also have offset 3/8" shafts, which I actually exchanged the center drilled shafts for as the B3 geometry correction specs called for 0.100" offset.
I have no idea what the original MP part# might be...but why not look up the likes of Harland Sharp and get either the center driller, or the offset shafts???
A bit of a follow-up on this discussion. There was a decent discussion on Speed-Talk about this, take a look here:
Comp QXI Lobes
More specifically, the comment by Mike Jones (Jones Cam Designs) highlights (his opinion anyways) the challenge with CompCam's fast ramps:
"...The issue is the...
What a superb timing to ask this question!!!
So I've been running a custom ground Comp Cams hydraulic roller cam (see attached spec sheet) in a 408 W2 stroker build here. Car is a summer cruiser though, so far from a daily drivers. However, I have put on a serious amount of engine RPMs given...
As the title says: 2920 W2 intake manifold is what I'm looking for.
I do not care how nice or ugly that thing is, my sole goal is to convert the carb mounting pad to a spread bore pattern (to accept my 9800 TQ) and literally do a comparison to the adapter plate installation (where the intake...
I won't argue what you say, but I will at the same time re-state what was already linked to in this thread, that being: FelPro has a very specific recommendation for HOW to install their seals (see attached PDF), and they in fact call for that off-set placement.
My point was only to state that...
Take a look at the attached pic, that's how I always set up my Felpro seal. The lip of the seal is positioned correctly as well.
Having said that, I have a continuous small leak today that I previously did NOT have on prior builds. The leak started right from the get-go, it hasn't increased...
LOL, here comes nuthin'...
Alright, so I did say earlier that this 9800 series carb is a test-bed, right?
What this means is that I have several base plates that I use, the key difference between these being the primary throttle plates have an air bypass holes drilled. I typically switch these...
So I had originally thought of adapting the W2 intake to a spread-bore setup, but sort of 'chickened out' seeing as I did not know to what extent reworking that intake top would impact the 'designed-in' flow characteristics.
I've attached a couple of photos of what I'm talking about:
1) the...
OK, a brief update as I got a chance to try out a few things last night:
1) AV dashpot
- disconnected it, basically to rule out some kind of a mechanical obstruction that might perhaps impact the ability of the AV to open completely
RESULT => no change, there was a bit of a stumble actually...
I think we are saying the same thing here, the key point being: the larger orifice at the same inlet fuel pressure will take a slight longer amount of time to completely shut OFF the fuel flow. Subsequently to account for this extra fuel volume the float level must be set differently (lower in...
Agreed, I will give it a go. I was going to do a test-run w/ the dashpot being totally disconnected first (just easier to do), but we've had a few rainy/wet days here and I haven't been able to take the car out.
I find this very interesting. I mean consider the process of filling a car's gas...
Let me clarify: it's not that it just instantaneously flops OPEN. You can tell that the airflow demand is actually what pulls it completely open.
Note the following: I had originally ran with a very light '1 turn past AV closed' setting, and with the high stall converter and 4.10 gearing I was...
NICE!!!
I figured the 9801, despite the small 1-3/8" primary size, would be a great fit for my stroker motor which spends about 99% of it's time handling street "chores".
For '***** & giggles' I have the CS-4846SA Comp all boxed up and will eventually try it...but seeing as that is a race...
