Ted, I have an Offy manifold I can let you use for the test.  If you can't find one closer I will send it to you.

I have an Offy 3x2 intake if you need it, but I am on the West Coast. If you need it, let me know and I will ship it to you.

Ted, I also have a Offy 3x2 manifold I can ship to you from Michigan. Replaced it with a 553. Runs a lot better.

Wow guys.  I’m impressed.  All I’m needing is the Offy intake without carbs but carb studs would be nice.  A trio of Stromberg 97’s are currently being used and the same carbs will be used on all the manifolds being tested.  My druthers is to return the Offy intake to its owner at the Y-Block Shootout at Columbus but in the event none of you will be there or you need it back sooner than this, then I’ll just ship it back when testing is done.  I look to do the first series of 3X2 tests within the next 2-3 weeks and that will be on the stock headed engine with a mild camshaft.  Testing the intakes again with ported heads is also a possibility.

 

The Edelbrock 3X2 intake that was on an engine in the shed is indeed a 553 although it’s not numbered on its top.  I’ve already removed the carbs and linkages from it and it cleaned up very nicely.  With the Offy intake throwed into the fray, I can come closer to duplicating the 1971 Popular Hot Rodding Y-Block dyno test and then see exactly how much more power each of two Edelbrock intakes are worth.  The 573 intake on the stock headed and stock compression ratio 312 is already handily outperforming the 1971 Popular Hotrodding Y-Block dyno test so it will be interesting to see how the Offy intake performs.

 

Jan, Mark, & Dan.  Just let me know who is sending the manifold so I can be looking for it.  Because the three of you so gratiously offered the loan of an intake, be sure all of you forward me your snail mail addresses so I can forward you copies of the dyno sheets with the various 3X2 intakes after testing is complete.  My personal contact info is at  www.eatonbalancing.com  .

 

But this brings up another item I need.  I can use another couple pair of #48 jets for the Strombergs.  Anyone have these laying loose?  The carbs are currently jetted 48’s in the center and 45’s on the ends and since switching to the EMC headers, the fuel mixture at full throttle is running on the lean side.  Engine was running pig rich with #50 jets in all carbs with the now removed Red’s headers.

Ted, I will ship you mine tomorrow, and you should get it in a few days.  I don't need it any time soon, so you are welcome to keep it as long as you need it.

Jan.  Thanks for the loan of the manifold.  I’ll be on the lookout of it.

Ted, went out and checked my Stromberg stuff. Unfortunately the only 48 jets I have are in my 97's on the car... I do have some 'parts carbs here so I will check what jets they have (that is if I can get them out, the carbs are well, shall we say, used and abused.

Jan, if you want, I could bring the offy back from Columbus for you.

Dennis, that would be great.  I can meet you anywhere you like.  I really appreciate it as I did not want Ted to have to pay for the shipping back to me.  Y-block guys are the greatest and I would really like to meet you and maybe have a meal together.
