Ted, just being curious, but how many runs do you think you have made on that test mule engine without having to do anything major to it? There's got to be a dependablity factor in there beings it's a Y-Block!

WHY????

I am wondering why you would think the Y-block would be any less dependable than any other engine?????

At pull #365, the short block was pulled down so a sleeve could be installed in cylinder #8 to take care of a lateral crack that was forming.  The engine was reassembled using the same rings and bearings as there was absolutely no wear on the bearings being evident.  Other than that, the engine has been rock solid.  This is the same basic short block combination that was put together in the Seventies and part of what I did on this end to prepare it for dyno testing was a rebalance with new rings and bearings.  I'll add that I installed bronze cam bearings to fix a twisted cam tunnel that was present when preparing this engine as a dyno mule.  The engine now has over 400 dyno pulls on it and still more testing with both heads and exhaust are in the works.

Bill & Lon.  Thanks for the accolades.

Vacuum advance was not used on the 3X2 test.  The distributor being used is a MSD p/n8383 and only the mechanical advance capability was being used in those tests.

Thanks, Ted. I looked up the instructions on the MSD Distributor and now I see that the VA can be locked out. Wasn't aware of that before. Not sure how that would work on a street machine...

The reason I bought the MSD for my Vicky was the lack of vacuum advance in the Mallory electronic I had on it. Lost some low end and fuel mileage without it. I plan to put the Mallory on the roadster as its much lighter, geared lower and I plan to drive it like I stole it anyway. Chuck

Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

I guess I will have to buy a John intake manifold for my 55 ford f-100 312 engine then.

the fenton intake has DM425 on the back, same as the late edmunds.

Wayne.  Thanks for that additional bit of information.  While there were no Fenton intakes here to test during that particular dyno session, it has been assumed that the Fenton intakes used many of the same molds as the older Edmunds intakes.  This was simply based on the similarity in castings between the two companies.  What you found helps to reaffirm that.

i just looked at a fenton, DM424, same as edmunds, small ports. they also used the DM427, same as edmunds, they just changed the name on the castings, small port also.
