Easy fix You are getting bargains I paid nearly $500 for a used one a couple week ago that was similar!!

No Sir = those are 1971 340 production carbs. The Competition Series are 850 and 1000 race carbs that are completely different animals. (I have been hoarding one of each).

Many of the 71 carbs were replaced under warranty by 72 carbs by the dealers. This was because of drivability issues! This helps to explain why they are hard to find. I do not recommend them for a daily driver The best performance calibrations were the 9800 followed by 9801/9810/9811 all...

Expect to pay $500 to $800 for a used core without any work on it.

The 71 are totally unique. They are faster on our stockers by 1 to 2 MPH The only carbs that are nearly as fast are the "Super Quad" 9800 carb. The next best are 9801/9810/9811. The reasons are too complicated to go thru hear and only of interest to Stock and Superstock Racers. The all require...

Are not the Green bearings weaker on side load and not as desirable as stock bearings for a street driver? That is what I heard years ago. I run them on the race cars and never had an incident and no seal.

I assume that they are Wheel studs = Perhaps for a different year or brake. The A body wheel Studs that I have ever seen that were lefts were 7/16 NOT 1/2.

We usually use Aftermarket Caps unless it is a pretty low HP Deal! We have broken several stock caps = No power adders either added!

In our Sonic testing the early 360 Blocks are significantly generally thicker walls and less core shift. Look for block with 34xxxxx OR 36xxxxx numbers. I would buy that in a Hot Minute if it was not 2,000 Miles away!

That is a bargain for a SFI Flexplate!!

What keeps me motivated and working 12 Hours every day between the Trailer Building and Race Cars and Equipment = I have seen my friends retire and sit on the couch and watch TV -- Then they are dead in a year or two. Kinda like a Car that is Parted too long! My kids promised me that on the Day...

Speaking from Experience = I can assure you gentlemen that you will NOT LIKE your 70's and you will struggle thru them! Then Again = I still beats the Alternative!

Wow: That is the clearest easiest to understand explanation that I have ever read on this. All I every do is confuse the heck out of people!

We build trailers........................I tell the guy that are looking at them: You but the Best AND you Only cry once!!! I pride myself on building budget race cars but some things are false economy. I

Absolutely right!! I have seen guys stamp the number on the rod and have it stress crack and break from that spot in 10 passes or less. Forget about the rockers = On my street 10 sec. valiant with just 140 Lbs on the seat they broke a 1/2 Dozen @ 1000 Ft mark (5500 RPM) Pins and rollers f...

You would need to set them up on the car to know for sure the length is correct. The adjuster positioning is fairly critical. Let me know if you need help measuring as I am in Vegas a couple days a week and would be happy to lend a hand with the measurement.

I have not heard of SNA Rockers?

I have been disappointed in the Ratio variation in the cheap rockers as well a the quality. Variation in the ratio from rocker to rocker is the "Kiss of Death" in our Stock and Superstock cars.

I hope so = It is factual true ( I know first hand)! There were several articles about it back them including the cam testing.

Mopar Perf. had a 74 (I think could of been 75/76) test mule Duster. with a big block in mid 70's They put glass bumpers on it and got rid of the Energy absorbing stuff. As I recall ( I am old) = It ran 11.3 with a very mild 400 and a 571 lift Mopar cam and 11.6 with a 509 Purple shaft. I...

I really don't think so.

Many late ones that I have taken apart did not have low gear.

Firm Feel has a Kit Car they used to race Circle track. Not a lot of similarity to production F body except Body shell. They bought my 63 Polara 330 SS/FA Max Wedge some years ago = Very Nice and Knowledgeable Folks! Top Shelf Components!

We run 600HP plus all year long in our 904's Even more in our Big block 500 with adapter! Only a few late 904's had the 2.75 low. Mainly Cop Cars and Taxi Cars Pro Trans in Texas makes a conversion to use them in 727s and I do. They also make Straight cut gear sets in almost any ratio if you...

Boy that I do not know. My son Robert does Pro Drift and won Auto Cross @mopars at the strip an few years ago but in my C7 Corvette. The F body cars have a unique front suspension and the front wheels do not turn sharp enough lock to lock to be an effective drift car. Maybe someone else can...

It is indeed a 318 2 Brl. combo I race a F body Stocker/Superstock = What would you like to know. They make a good race car! Google: John Irving Drag Racer To see the Sedan and the Wagon Both have been NHRA National Record Holders for years

I will be @ Big Pomona Swap Meet OR I would be there!

If you put all the best lightwt. pieces in the Dana 60 = It weight difference is nearly negligible. just getting the Tracklock Sure Grip Carrier out saves a bunch. Also Rifle Drilled Axles. I understand the pinion angle is more efficient on Dana 60.

I have been doing this a long time = My vote is to put in the Dana for sure. I used to break plenty of 8 3/4 stuff with 3400 Lbs with a 4 Speed and 550 HP!! No problem with the Gas tank in my dusters/demons

It would be useful to know which a Body hood.
