2 v conversion?

[kenny170]

Can a 2v conversion be done with an automatic transmission?

Howdy Kenny:

Yes, the 2v conversion can be done with any of the small block sixes. But, I have to ask, what is your goal in considering this mod?

Adios, David

Just considering all my options before I begin a major rebuild. I already have a late model large log head. is there anything special I need to do to make an automatic work with a 2v conversion?

Depending on the app , a kick down conversion ( Lokar makes one that can wok ) needs to be addressed

I had the stock C4 kick down that bolts to the intake and adapted it to the Rochester 2GC pretty easily.

what all are you going to do to the head? I spent $1500 on my head,first purchasing the head then adding p&p, oversized valves, 2bbl conversion with putty build it (add $400 if your going brazing) valve guides, by the time you're done with the head, you could've had the alum head...

now if you keep the 1bbl hole and put a 2-1bbl adaptor on it, then okay, save your money and get the alum later...

I only let you know as sometimes it's cheaper to spend the $ now instead of later.

And I did a direct 2bbl conversion with a valve job and milled head for about $300. It all depends on how you do it and how much work you can do yourself. Personally I don't think the 2bbl on an adapter is any better than a big 1bbl, or not much better.

jahearne's example. He uses the type of linkage Ford used in the twin carb Boss 302 TransAm cars, and the kickdown linkage is the same as the C4 auto 1973-1975 (3.0 Essex V6) German British Ford Granada and Capri automatic and the 1974 to 1986 C3 tranmissioned Capri/Cortina/Taunus/Sierra (German and British 2.0/2.3/2.8 liter Cologne V6) cars. Locar use basically the same system, and its very well made, probably the best money can by. I used the original item in my 2.3 Cortina, and my C3 then C4 were both cable operated.

Despite the huge differernces in bolt patterns between the wide based 2100/2150/2300 carbs, in terms of hard dimensons of the throttle linkage, the 2-bbl 2100 Autolite, 2150 Motorcraft, 2300 Holley non staged 2-bbl and the 2Jet 2GC Rocesters all use the same center spacings for their throttles as they were designed for Rochester type settings in small and big block V8'S since the 50's. Whenusd with a tThrottle kick down lever, or even Throttle Valve cables like they used for the more complicated AOD transmissions, the set ups are very easy to arrange, with the Locar kit being the ulimate solution and its set up is world class. As I said, the system is based on the common European V6 cable operated C3 and C4 system used in there Cologne and Essex V6's. You just cant go wrong with it. Getting rid of the old rod operated kickdown allows you to fit a raft of good carbs to the log head engine, and it'll save you big money.







If you look at the Holman Moody 302 Trans Am race cars from the late 1969, the same technology is there, with a rocker arm to pivot the Holley Dominator 4500 carbs in the same way jahearne has done his 2-bbl 2100 carb.



As for the carb options, can't see much wrong with parkwood60's little Rochester 2-BBL
