Short Block Quality Test

By DAVID VIZARD
PHOTOGRAPHY BY THE AUTHOR

I have long been a little leery about buying a mail-order motor unless it's factory stock and the intent is to use it as a basis for greater things. After some close friends had bought engine kits of substantially less-than-stellar quality from a large, well-known discount mail-order company, I became even more leery. This was all in the back of my mind when my 140,000 mile 5.0 started using oil at the rate of a quart for about every 10 runs on the chassis dyno. It was clear that, as a test vehicle, this machine's days were done.

With a backlog of several pairs of heads, half a dozen cams and three or four manifolds to test, I needed a rebuilt bottom end fast. To be honest, with a stack of articles to get out,! did not welcome the prospect of pulling and stripping the motor, getting all the reusable parts (such as the block, crank and rods) cleaned and hunting down pistons, bearings etc.
Seeing my dilemma, Dale Sciranko at Custom Performance in Charlotte suggested I get a DSS bottom end. His company has used a substantial number of them and has found going the crate short-block route with a company that builds reliability allows a fast turnaround. This greatly helps when required to meet the needs of customers wanting the next best thing to instant gratification. Of course, factors such as getting quality end results in terms of performance and reliability figure heavily in the equation. In Dales words, the deal is this: "They ship you a meticulously cleaned block equipped with moly ringed, forged flat tops, a reground crank, an ARP bolted and balanced rotating assembly, oil pump, and mains girdle. All you need to do is install the cam and heads of your choice and you are back in business."

Since Sciranko runs Custom Performance on a strict quality basis, I took his recommendation seriously. In' fact it gave me an idea. Normally DSS ships short-blocks in assembled form. But how about if I got one of its short-blocks as a kit, checked every part for quality and accuracy and let MM&FF readers know what they might expect of DSS? Assuming they went for this deal, the intent was to have them ship the same day so there was not time to supply a "special" that would skew results.

I called Tom Naegele at DSS and pitched the part of the plot he needed to know to make a decision. I kept the "same day shipping" clause till last. What I needed was a stout bottom end to test everything a hot street fanatic might want to read about including nitrous, and Naegele was more than happy to oblige. It was
then I said I needed it shipped right away. Naegele replied that this might be a problem. Due to being in the middle of a shop move to a huge new facility, they had run inventory low. A check revealed that what I needed was not in stock but could be done in a few days. After explaining why I wanted the motor kit right away, he assured me that they had no time to do a special in the middle of a move and what I would get would be just the same as all the other customers. Although disappointed, the full intent of my original plan proving unworkable, I still decided to go ahead. This was based mainly on the fact that I knew Sciranko at Custom Performance would not knowingly touch substandard parts.
About 10 days later the motor kit from DSS arrived and the first thing that impressed me was the meticulous packing involved. Right at that moment I got the feeling I was going to like working on this DSS unit.
