If they are running the largest crank pulley it seems like they would already be running the 8 rib setup...

 

Why? The largest one we could fit was about an 8.5" crank pulley and not have any waterpump contact issues.

We're almost done, running around town all friday and today for parts, this sux
Btw, the heater hoses hit the charger intake elbow, so much that they have to be pulled out of the way for installation.
We'll be done with the charger install today, dyno it, then do the cam, then dyno it.


The 383 was a 9.5compression engine, forged, cam, blah blah. It runs very strong! But, we built the engine for more, we would just like to work the engine to it's fullest potential.

I'll have to look into that front drive kit, may be the only way to go.

 

I guess I can say that I've seen a larger crank pulley on a 6 rib setup.

 

 

so ready for this.....

 

That looks great. Cant wait to see some results.

 

This is why I dont care for the front drive on the maggie's, You could always have the blower drive gears re-cut to change the drive ratio...........

 

TTT,

Forgot to post up the results,

Recap:
5.3L Tahoe
TVS1900 appx 6-7psi
Small cam, headers

Truck put out 428hp and xxxtq (i'll post up graph later).
Get this, since the Maggies put out so much lowend torque, I chose a cam that had more topend. Max power was about 7,000rpms, yikes. Pulls like a sob on the topend, it's real hiway killer!
It also ran a 106mph in the 1/4 with big *** 22's(i think) Rockstars.
That should be good for a very low 13sec, possibly a high 12sec.

later,
allen

 

7000 rpms with a 5.3 tahoe damn....

I don't even rev my solid roller 427 that high.

 

Those are some dam good numbers!
