Did the Protrans Smith Daytona run that motor?

I don't know about Gary's car.

To my knowledge, the Smith's Daytona was always a 4 barrel.

In regards to GTX John's comment about paying $100.00 to see His Royal
Rudeness say things to Jared's face, I will kick in $100.00 as well. But
more importantly, I will pay $200.00 to see him be rude to Jared in front
of Julies face. You must be very careful with professional accounts, They
will subtract your limbs, multiply your pain, divide what is left, then add a
match to the remains.

That said, your $14k investment in your program will not be nearly enough to transform the OP?s bracket car into a legal, competitive, stocker much less a competitive super stocker!

Still waiting for proof of all of these "awesome" Wallys......

I have tested 2 of them on my flow bench and they flowed 566 and 582, I'm guessing their original rating was 575, the 582 one with a large 65 Monaco air cleaner base flowed 598 CFM. The 440 would need a full cage in SS as a GTX or in GT. If you don't have a cage the 70-71 383 would be best for GT as it can fit GT/LA which is not typically a very populated class. The AVS can flow close to 650 with a good base and the 383 Holleys that I checked were 724 and 746 without putting a base on them, both have the same HP rating in SS with GT being a bit higher. None of these will go .8 under without great heads, big money, Pro trans etc. The 70 383 will go under the index in GT with good heads, intake and ideal cam.

Good info. The car is legal to 10.0. It is minitubbed and narrowed; and I?m not changing that, so SS is really the only option.

So the prevailing opinion here seems to be just as I felt when I looked at the outline for a ‘67 383.... carb too small to make real power. Somewhat reassuring.

What about a 71 400 combo? You get around 415 available cubes, 452 heads, and maybe most importantly, a big 850 Thermoquad. Not sure how this carburetor is viewed as a race option, but at least its big enough to not be the cork in the combo.
The downside would appear to be compression; Down around 9:1. Does an engine with that little squeeze respond to modifications very well?

Also, I was watching one of Bobby Fazios videos. He was talking with a guy that said he was running The Low Deck 440 combo. I went back and listened to it 3 times to make sure I heard him correctly. Anybody have any idea what he was talking about??

I think the 383 or 440 in regular Superstock.
SS/IA or SS/JA for 440 and SS/KA or SS/LA with the 383
would be viable to run under the index even if
not a world beater.

West Coast = Best Coast. Looking forward to a great start to the year in Phoenix this week!

[Jared Jordan]

The 400 isn’t terrible. The knock on some of the later engines is how far down the hole the piston is. The prevailing opinion is that might be, at minimum, difficult to overcome. I think the 71 would be the best of them, as it only got worse from there. The Thermoquad is a great carb. GTX John likely agrees with me.

Although I didn't see the vid, the low deck 440 has been accepted in SS but the HP factor on any 3.75 stroke engine except the 64-65 Street Wedge with that small carb will require a full cage.

I believe Greg Gay runs the 400-4 barrel in his Mirada out here on the east coast. It is not a bad combo. I looked at it as an alternative to the boat anchor I am putting in my 66 Dodge. I would look at the 73 400/265. It is rated at 20 hp less than the 72 motor. NHRA rates the 72 at 330 hp and the 73 at 310. The Thermoquad is a great carb, and a lot of people forget that it was originally designed by Carter as a race carb. Not sure how heavy your car is, but the 73 motor at 3735 puts you in GT/LA. 11.05 index, and no cage needed.

Another to think about in GT is the 70 Chrysler 440/350. It is allowed the same bigger Carter as the 375 hp motor, but you must claim it as a Chrysler. The Dodge/Plymouth combo uses the baby Holley. That combo puts you in some tough classes though (GT/H-ish) at a decent weight (3500-ish?)

As for the 440 low deck, it is probably a 440 combo using a 400 block with the 440 rotating assembly stuffed in it. The downside of this is you will need a short custom piston. Not sure how much money you are wanting to spend, but that option adds up fast. Most all 440 combos are going to put you in a higher GT class. GT/A-K require a cage. GT/L and down do not.
