2v conversion - where to have it done

[Shelly6]

Hello!

Anyone have a recommendation on where to take/send a D8 log for a 3 angle, a back cut, a little milling for compression, maybe a little porting and, most importantly, a 2v conversion for an Autolite 2100?

Denver area or will send it wherever I should send it. Any shop can do the valve job and some mild sprucing up. What I'm nervous about is the 2v conversion. If I bring pictures and text from the CI archives, will most shops know what to do and do it well?

I assume I need to supply them with a plate they weld to the log that I can bolt my carb to. Is that something somebody already makes or does the shop need to figure that out?

hi Shelly.
I'm kind of a DIY guy,so I just got a big grinder to at least cut down that one hole.I did three heads at the same time.A 73 a 78 and mine, a EO head.
Now I tinker,so I had both Classic Inline adapters,for the 2100 and the weber.A very small amount of drilling and I had two bolt holes on each adapter match.
I took the 80 head to a specialty oilfield shop that did brazing. Out of 300 machine shops in the Odessa/Midland area ,only two do automotive,and they don't weld/braze.
after the three angle,.060 carb mount clean up and exhaust mating clean up,that head cost me north of $600.

My machinist gave me a name for a local welder that uses a standard welder and a rod for cast iron . same machine work (except for the exhaust clean up) and those heads cost me $350 apiece.

drilled and tape six holes and I can now run a weber or a 2100.
And my 2 buddies with the 70's heads won't let me buy any beer anymore when they're around.weber for around town,holley for camping in the mountains.Try taking the CI pics around to some welders first,might save some money.
Just saying............

OOPS,forgot to mention,those adapters are bolt ons and a guy bought up CI inventory/ manufacturing rights(?).
the adapters make it easy,all things considered,and they are prettier than the 2 I made before I found this site and found "the book".
search around and you'll find him on here for the adapters and other CI parts.
Ive got a bad case of Can't Remember Stuff.
hope it helps some..................

I bought the aluminum adapter from the Classic Inlines (looks like Vintage Inlines is offering them, thankfully) first so I could lay out the enlarged hole. Once I understood how it was supposed to lie, I took a cutoff wheel on a 4.5 inch angle grinder and with a steady rest carefully cut off the boss where the carb sits. I touched it up with a file, ovalized the hole with a porting burr from Eastwood, then drilled and tapped the holes for the screws that hold the conversion plate in place. I was going to JB weld the gaps between the adapter and the manifold, but the machine shop I took it to suggested he have a guy braze it, to which I agreed.
Obviously, do this BEFORE you have any work done, but you should get the head magnafluxed first to be sure it's a good core.
If you're not inclined to pick up an angle grinder and think, 'what could possibly go wrong?' then yeah, I'd take photos of the process from this site and show them to your potential machinist. I'd be shocked if you can't find a good shop in the Denver area who has heard of this conversion.
Good luck!

Once upon a time, there was a machine shop board on this forum. Check there to see if there is anyone listed for your area. Otherwise there is a member on here who does topnotch work. Ping 1hotvega. I belive he is cleverly hidden on ebay under the same handle.

I just went to a local guy who is well known for building race engines. I think he was secretly excited to do sometjing out of the ordinary because he did all the work himself and didn't delegate anything.

the best 1 I've seen wuz right here (pic included) where I believe material wuz added 1st, B4 machining. It wuz an "M" head.
Seems like THE way 2 go…
I'm sure Matt has an adaptor.
