2 brr direct mount

[Joost]

I've got a Holley 2300 350cfm that I want to mount to my E0 hex-log head.
I went to the machineshop for milling the intake. Cause the hex-shape it's not that easy to get a flat surface, i don't want to have any cracks in the log 'cause it's getting pretty thin now.
I've read in early posts that it's best to weld for a bigger surface.
Is there somebody with a picture of his setup. A detail of the shaved log maybe so I can see how I have to weld it.
I gonna put an alu spacer on the log to bolt on my 2 barrel carb.

Tnx in advance.

Hi,

With an E0 head you shouldn't have to do any welding. The E0 hex heads where wider than the early heads. It's my understanding if you want to direct mount on the earlier heads then you needed to weld but not the later hex heads.

Hi again,

I'm talking about the log itself being wider not the whole head. Just wanted to make sure I didn't cause you any confusion from the confusion within myself.

I understand what you're saying.
The problem is, when I want a completely flat surface that's 's big enough for the 2brr i have to mill futher and the iron is gonna be very thin, this is caused by the rounding of the hex shape or am I getting crazy?

Joost,

If you search for "Holley 2300" you should find a post with some pics from Wsa11. He did a great job showing and explaning what he did, if you look close you can see where the material was welded in. I think he said he had brazed it on.

Anyhow, I have a '78 head with the hex log that I was debating a direct mount of a 2bbl. Looking at it, around the outside edges of the carb base it does seem like it extra material would need to be added to get a wide enough flat surface to mount an adapter plate to it. IF not I was thinking you could JB weld any gaps closed, but that would be just a bandaid.

Good luck,
Jay

Hi,

Tnx for the tip!
I've found the pics of WSA111

Probably me but can't exactly see what where he had welded the log...

Tnx.

Maybe this helps. This head was welded a little less than wsa111's, but you can see the old 1V mount and the two places it was welded a little. Both the original bolt holes are visible, now after taking this pic the outer one is already filled.

Tnx a lot for the quick answers!
A picture says more that 1000 words.
This forum is great.

Friendly greets

Can I weld it at myself with my MIG welder (Argon/CO²-gas)? Or is it a better idea to get it welded in the machineshop? Do I have to prehead it to prevent the head from cracking?

Tnx
Joost

Joost, if you braze or weld you will have to preheat the head.
There was a post by ric wrench saying he used a product called muggy weld where you don't have to prehead the head.
www.muggyweld.com
Look at their website, it looks pretty slick.
If you do preheat your head to say 400F, you will have to replace all your freeze plugs & probably have to resurface the head surface because of warpage. Good luck with your direct mount, not as good as an argie or OZ head, but a heck of a lot better than the pitiful 1 barrel carb. William
