Since I know there's a TON of experience on here:

Does anyone have a rough estimate of how much torque and horsepower I might have gained on a mildly built 289, in switching from a stock 4bbl intake to a Weiand Stealth intake?

I know it saved me about 20 lbs in weight.

Thanks guys.

It definitely depends on how the rest of your car is setup. More info is required.

If you don't want that old intake anymore let me know cause I know someone who wants one.

The cam is a Crane Cam P/N 363941

It's a 484/512, rocker arm ratio of 1.6.

The heads have been ported and polished with oversized chevy valves installed, as well as a 3 angle ( i think) valve job.

Annd I believe the block is bored .030 over.

Any more info needed? Thanks guys!

66MoneyPit- I have no use for the old intake. Just let me know. If you want pics send me your email and I'll get you some.
