Weiand Stealth Intakes

The 12 is for DOVE head ports the 21 is bigger for CJ size ports, other than the flanges the are the same

In my opinion ... there is NEVER any reason to buy a new 8012 manifold.
It won't fit a CJ head yet the CJ manifold will fit with the smaller D0VE size ports and not lose any power; even with the port mismatch.

Just Commenting :

Best Price on FleaBay  New 8012 - $223.95

$35.00 more for the privilege of CJ ports

What engine combination are thinking of putting this manifold on and for what vehicle and what vehicle usage?

They re-flanged the CJ intake for those unaware people who read to many magazines or think the ports just need to match.

Buy whatever you want ... other than a few bucks there is no difference in performance. Now that 8012 won't cover Cobra Jet ports at a later time and is more difficult to sell.

If this is the right one, it's a 100 bucks more, just a thought. If you like low oil pressure at idle on a hot engine and noise the Rhoads are the ticket. 4" exhaust, Hmm there goes some low end torque I bet.

This may help you with the three barrel on some intakes.

I look at a lot of old Holley stuff and that is the first one I've seen also. As long as you get the back barrels to clear you should be good. Be careful with the vacuum pod they are pricey too.

What is the first gear ratio in your Doug Nash? Sounds like a cool ride by the way.

Hard to say on the gears, depends what you want to do I guess. The 3.27 and a 3.25 in the rear come to 10.62 in first. A C6 would be about 8/1 in first for comparison. A 2.75 out back with the 3.27 would make for a nice freeway cruiser and still have a pretty stout take-off. Check your PM's I sent a little 3Bbl. info you might like.

Or put taller tires. From the way you described the ride I was envisioning big soft compound Mickey's tubbed in with the 4" tail pipes coming out the back. That 3.25 3.27 first is about the same as a 4.30 with a C6 in low. Building a big block/manual transmission ride like this and trying to set it up to hook with regular street tires seems kind of counter productive to me.

Run alot of cam and big exhaust (4" ), and maybe an aluminum flywheel,  kill bottom end torque and I might have enough traction for street tires. I think depending on tire size, this would top out in 1st gear at about 40 - 45 mph.  I used 3.25 because that's what I have siting on the shelf. I have other 9" jackpots, but they are all numerically higher. I may put this together and then have to hunt for 3.00 or 2.79's

27" (L-60)Tire 3.25 Rear 3.27 First Gear 6,000 RPM=45MPH  

With the 2.95 First Gear at 6,000RPM it comes to 50MPH

MPH= TH X RPM Divided by GR and then divided by 336

Should have snagged those Hoosiers.
