Richard, I see there is no oil line from the block fitting to the fuel injection distributor. Hopefully they removed the internal gears from the distributor.

Nice photos. Thanks for sharing.

Thanks for the kind words Ty. These parts are 50+ years old. I have no idea if they will work on the engine you are referring to and as far as I know, no one is making any of these parts nowadays. Richard is correct..........................a set of real Italian made 58mm Webers are very expensive.................. as is the MT block, one of only 15 Mickey cast for his 1967 Indy 500 effort.

Good luck with your car..........................keep us posted on your progress.

That's a static display motor. I suspect it's one to the original. Last time I heard they were using a Hendrick motor in the car. That motor though is equipped exactly the way the display motor is.

Ty,

GM has definitely made BowTie blocks with all bolt holes and accessory holes in stock locations. I assume they still do. You can (or could a few years ago) even get an aluminum Bow Tie block that was fit, form, and function compatible with stock, iron passenger car blocks.

The block is part of the equation. The other part of the equation is the heads you bolt to it.

Buy 23 degree heads with stock intake ports and you can bolt a Pierce/Weber manifold right on.

Hope this helps....

Jim

Jim here is some information.
===================
Here is what Block I think I have:

http://www.superchevyperformance.com...p/12480175.htm

Iron 400 ci, with one piece rear seal, 350 journal? Not sure about this last on.
====================
Here are the Heads:

http://www.brodix.com/heads/small-bl.../track1-head23
====================
Here are the Shaft Mounted rockers I have. I didn't look us the actual part number.

http://www.crower.com/media/masterca...ex.html#page=3

====================
The Cam is a custom grind with about .600 lift, and 230* of duration @ .50.
LSA is about 108

It is not very vacuum friendly.
===================
Compression is 11:1
===================
All forged bottom end
===================
Max RPM is 6500
===================
Supposed HP 500-550 at the crank
===================

Does this help?

I really want a Cross Ram whether carb'd or efi on my Camaro (400 sbc)

On the GS I really want to find an EFI Cross-ram intake with weber like throttle body's. This would be for my Mast LS3 (427 c.i.)

Please point me in any direction your think will help, or do you need more information?

Thanks,

Ty O'Neal

Ty,

I know nearly nothing about LS engines, so no help there.

However, the 1st gen block and heads you've specified appear to have everything in the stock locations. I don't see a problem mounting a Weber cross ram intake. Or, for that matter any stock-ish intake manifold.... carb, EFI, whatever.

BTW, the claimed air flow vs. lift for those Brodix heads is impressive.

BTW^2, the bow tie block probably weighs somewhat more than a civilian, passenger car, iron block. Our Grand Sports are already nose-heavy anyway. Consider moving some weight (battery comes to mind) to the rear of the car and reducing the weight of what you can't move.

Hi Jim:

The 400 sec is in a 69 Camaro I have. I have been struggling whether to leave it in there or just put an LS Engine in it. Aluminum, makes gobs of power easily, and gets great gas milage. (Whats not to love!)

I've been struggling with whether to leave it in the car or pull it for an LS.

If I could get the high impact visual, as well as it calming down the cam, it might change my mind, otherwise I would just might have a very nice sbc for a later project.

As far as the GS, they make covers for the LS valve covers that look exactly like the "Corvette" ones of yesteryear. The intake however is just out of place. Maybe running a carb is the trick, but a Crossram with weber efi throttle bodies, Now we would be talking!

I've got a few extra engines I've picked up over the years, an extra one wouldn't bother me. (BBC 454, sbc 327, 2 x Buick Nailheads etc.)

Anyway, I'm just looking for a way of making the best car I can. When you finally get to a position where you can get a car you have wanted for 40 years, I would like it to be a perfect as I can make it.

Probably over thing thinking things but its a fun problem to have.

Thanks again,

Ty

Default GS heads

Hi all, I'm new here and I am trying to find out if possible which car my heads may have been used on. Also some idea of their rarity and value.

Thanks in advance !!

Those heads are reasonably rare. How about posting a little more information about them? And, while you are at it, fill out your profile. Doing so will help people get to know you and will produce better responses to your inquiries.

I'm on here trying to find out about them because I don't know anything about them. I bought them at a swap meet many years ago and had them rebuilt a few years ago. I am a Camaro guy but Ive owned a few corvettes over the years.

Does anyone have any info on how many were made ? Or which cars used theses heads? Maybe take a guess what the 18 stamped numbers mean ! I assume it is a code of some sort. Maybe there is a good original pic of a car/motor that is stamped similar? Anyone here have the same heads to compare? Thanks in advance !

Wow, Beautiful heads. So these don't have the end coolant access ports. What are the current valve sizes?

Thanks, Paul

I don't think GM made any sm block heads with access ports on end of heads in 63. If I recall, they instaled 2.05 valves when I had them rebuit.

He may be referring to these. Note the raised boss with the blue anodized pipe plug in the end of the head. They were for plumbing a drain line to the oil pan for faster oil drain back.

Yes, I was thinking about those heads. Love those too. I know that engine assembly. You sure that's hitting oil drain area? The end drains are towards/nearest the intake side...

Same port config made me think about it, even with different casting #.

Do you mean no ports on the either end of your heads? Yeah, that could be the only thing that separates the two casting #'s. Are there stampings on the other end too? Nice photos of the top/bottom.

Figured the fittings are alternate coolant access/porting.
