When inspecting the new cam I noted that the oil groove in the center journal was only about .010" deep.I checked 2 stock cams and got .028"& .030" depth.I stuck the cam in the lathe and made the groove stock depth.Question is I wonder if I needed to do that? I used this same type Isky cam in a 312 40 some years ago and didnt do that. Dont recall any top end oiling issues.Anyone have any ideas?

There was also some concern about the area around the distributor gear and interference. Speaking to the groove, with the new Durabond bearings that have a ID oil groove and an OD!!! oil groove this should not be a problem. I think the veteran Verne Schumann worked on this with Durabond. What cam bearings are you using by the way? Daniel Jessup Lancaster, California aka "The Hot Rod Reverend" check out the 1955 Ford Fairlane build at www.hotrodreverend.com

NOTE: All new cam cores for Y-Blocks are manufactured with insufficient oil groove in center journal resulting in reduced oil flow to rocker arms. WE CORRECT THIS PROBLEM ON ALL NEW CAMS WE SELL!!!

About that long ago I helped a guy pull this 292 out of his 59 Ford and install a 390\4 speed combo.I bought my 55 Ford this year and a couple of months later I saw him at a cruise,told him about the ford and he said"why dont you come over and get that 292 we took out of my 59?" I went and it was STILL sitting in the corner of the garage where we had put it! He also gave me a bunch of NOS parts(bearings etc) and an Offy 3X2 intake! true story.

Per John Mummert's web site: *Engine block casting I.D. above the engine oil filter on the driver's side...* EDB-E - 292 cu. in. V8 1958-59 cars and trucks to April 59. (312 in Mercury) B9AE-F - 292 cu. in. V8 1959-60 cars and trucks. (312 in 1959 & 60 Mercury only) IF your block is a B9AE or B9AF, it should have the longer main bearing cap bolts that Ford went to in the Y block during the '59 model year 'til the end of regular Y production in the '64 model year. These are a plus, particularly IF you should hop-up the engine… ________________________________ *Cylinder head casting I.D. adjacent to cylinder head intake ports:* CASTING# Cu.In. Int. valve C.R. CC’s H.P. Carb. VEHICLES 5752-113 292 1.92" 8.8:1 72cc 200 2bbl Ford cars 5750-471 292 1.92" 8.0:1 82cc 2 bbl LD, MD, HD Truck 5750-471 312 1.92" 8.7:1 82cc 210 2bbl Mercury IF your heads are 5752-113s, IMO these are as good to have as the historically sought after '57 ECZ-Gs. The 113s are posted, have relatively small combustion chambers, and have the large intake valves. The 5750-471s are a good head, too, BUT have BIG combustion chambers if you don't have domed pistons, a supercharger, or a turbocharger... *______________________________* *Let the fun begin!* NoShortcuts a.k.a.

Unless your 292 is just a 2 barrell setup, a test not long ago of Tri Power setups on a Y-block, determined that the Offy was the least effective of seven tested. Also, there can be distributor advance problems with those early 94 style carbs depending on what distributor is used etc. There are explanations back some on this site & in Y-Block Magazine etc..

The block is at the machine shop right now so I dont have the casting# handy but it takes the longer ARP main bolts with no problem which IIRC makes it the later 59 block?

Keep us posted on your progress! NoShortcuts a.k.a. Charlie Brown near Syracuse, New York
