Looking good!

Congrats!

Yea, it was a great car I drove and enjoyed that one quite a bit! Funny story I traded it twice. First time was on the 70 W30. 4sp Conv in the background but ended up buying it back and keeping for another year until this one showed up... too many cars not enough time!

Agreed. I saw it at MCACN, and thought there was a beautiful car hiding in there. And here it is!! Well done! Enjoy her.

Opinions Please?
I've got service replacement SD Carb, #17054910 dated 0136. It looks complete and in good used condition. I think I'd like to sell it, any idea what it's worth?

What is the best flowing SD you have heard of or seen? Do you have flow sheet? Anyone have flow sheet from a SD Super Stocker?

They go 285 with a good basic port job. I have done S/S heads but this was before they allowed any porting. Nunzi told me he could get 330 out of them, but I'm not sure if that was on my bench or his bench.

[Jim Robertson]

Thanks Paul. This set flowed 275 when I purchased them but were very noisy on the bench. After a bit of short turn fill we are at 340. These were possibly prepared for super stock and were various shapes and sizes. We felt these were a great candidate for a pushrod move and thus we did .225". We are at 335 with very smooth sound and good velocity. Exh flows over 240 so balance is good. Should make a phenomenal street 455

'73 with SD along side.....
Better READ the whole thing..

For a minute there I was hoping this was the car I built 20 years ago.
DAM!!!.......I wish I knew the whereabouts of that car.

455ick, Your car looks amazing now without all the flames and pin striping. I thought it looked cool before, but now it looks even better. Nice job!

Jim, those are some great numbers. The SD heads I've flowed have all been very smooth, much smoother than the RAIV heads. I've looked at your website before and you do outstanding work. Are you going to be posting some pictures of the SD heads there? What lift did you see 335 cfm and what size intake valve did you use if you don't mind me asking?

Looks Great. When you say base coat do you mean that the car had a B/C on it or do you mean the original paint?

[njsteve]

By "base coat" he means the original factory red paint. The car had a clear coat over the flames which were carefully removed.

[Jim Robertson]

Paul these so far flowed 282 @.400", 296@ .500", 322@ .600", 327 @ .700, 335@ .800 and 340@ .850". I will be posting some pics on my website and here. Intake valve size is 2.125".

[PAUL K]

Jim, thanks for sharing. Will they be going on an aftermarket or factory block?

[Jim Robertson]

These are going on a 4 bolt 455 block. Mild solid roller cam, ported victor intake, 1050 dominator, 2" hooker headers.

I went with my friend to the dragstrip in his red '74 Super Duty Trans Am. We only got to make 2 passes before the rains came. The first pass was a 13.71 @ 101.9 mph, and the second pass was a 13.8 @ 101.2 mph, and you can see it in this video: https://youtu.be/VlJcKP8zbLU

Anyone know when 1974 SD455 INTAKE changed from LS-2 to LS-2X? I have an LS-2 but would need to trade for an LS-2X manifold. I am starting collecting all the parts I need to restore the 74 SD white TA.MY March bld car is LS-2.Thanks.

[johnta1]

I'll post this link here too.

LS2X Intake

Post by 'toomanybirds':

I have seen examples of both the "49" cast with the "5107" stamped, and the whole number "495107" stamped.

These intakes were used on early 74's through about Jan of 1974. They all have the K172 date, as the 73's did also. These intakes are all the same casting, the 73's have the 494405 cast/stamped on them and also have the drilled and tapped hole on the RH side of the water crossover.

It appears that left over 73 castings were machined, restamped, and used on the early 74's.

All of the LS2X manifolds I have seen have the 495107 number cast, not stamped.

The photos in SDD's post are of an early 74 intake. The vacuum switch on the intake runner is also a 74 piece.

And:

Yes Bob, the early 74 intakes were LS2, not LS2X.

The early 74 SD cars used the left over 73 engine parts. You will find Nov-Dec 72 cast dates on the heads and block on the early 74 SD cars.

It seems that the supply of blocks ran out first as I have seen Jan 73 dated blocks on some early 74 cars. The intakes changed to the LS2X some time in Jan 74, I have seen 72 date coded heads on some late Feb 74 built cars.

I have not seen any intakes or heads cast in 74, all have 72 or 73 date codes. I have seen SD blocks cast in 74 (including SR blocks).

All 73 SD engines should have cast dates in Nov or Dec 72 on the block, heads and intake.

I have seen one 73 SD TA with a Jan 73 dated block, it was an obvious re-stamp.

If anyone has seen anything different than this, I would like to know.
