![]() The stroker short block was further equipped with a powerful COMP Xtreme Energy, hydraulic roller cam. The XR300HR cam combined a healthy. The two heads were run on a 383 stroker created by combining a 4-bolt block with forged internals that included a stroker crank, h-beam rods and JE flat-top pistons (with Total Seal Rings). This combination of impressive flow and affordability made the Dragon Slayer heads a formidable weapon in the battle for performance.Īn epic battle of this magnitude must of course, take place in a grand arena, and ours was the dyno facility at Westech Performance. 700-lift, small-block cams are somewhat of a rarity. Not only did the flow rate of the as-cast port exceed 300 cfm, it did so at a more useful. Basically the Dragon Slayer head was an as-cast version of a CNC-ported head, meaning it offered the flow rate of the CNC program without the expense. Starting with their Track 1 head, they first developed a CNC program to maximize the flow through the desired 225cc intake port, then digitized that port and recreated it in a casting. To develop the Dragon Slayer head, Brodix did just that. If we go back in time and look at the development of a cylinder head, the best way to maximize power from a head is to apply an efficient CNC-porting program. In fact, you might be wondering why Brodix would go to the trouble of offering an as-cast head in a world dominated by CNC porting? The answer is quite simple, as the as-cast Dragon Slayer was in fact a CNC-ported head, well almost. The Dragon Slayer heads from Brodix were more than your average, run-of-the-mil, as-cast, small block heads. Now we toss in the fact that, unlike the E-Bay heads, the valve spring package supplied with the Brodix heads offered sufficient valve control all the way to 6,700 rpm and Excaliber was looking for some dragons to slay. As we would find out, the promised flow was nowhere near the actual flow and difference in peak flow was less important than the changes in average flow through the entire lift range. 600 lift, where the E-Bay heads advertised slightly under 300 cfm but at. The Brodix heads took this round by exceeding 300 cfm and did so at an impressive. Though valve sizes and port volumes were certainly indicators, both heads advertised flow numbers near 300 cfm. Port volume was another matter, as the intake port on the CNC heads exceeded 230 cfm making it slightly larger than the 225cc port used on the Dragon Slayer heads. The Brodix heads held a slight advantage in the valve sizing department, as the 2.08/1.60 valve combo was slightly larger than the 2.02/1.60 valves used on the E-bay heads. In the tale of the (advertised) tape, the two competitors looked pretty equal. From a pure cost standpoint, the near $1,100 E-bay specials seemed to hold the advantage over the $1,800 Dragon Slayers, but remember, price points don’t make power. To illustrate this point, we decided to compare a set of bargain basement, small-block Chevy heads purchased off E-Bay to a set of Brodix Dragon Slayer heads. ![]() Though we love a bargain, care must be taken when choosing from the many offerings, lest you forget the old saying-you often get just what you pay for! In simple terms, this means that low cost often comes with other sacrifices, including quality, performance, and longevity. ![]() Would you put your trust in a questionable sword or spend a few extra shillings on the mighty Excaliber? The proliferation of inexpensive “offshore” performance components has flooded the market with an abundance of low-buck possibilities. Imagine you are summoned for a quest to slay a deadly dragon. There is nothing better than getting a $100 intake manifold for $50, or even better yet, $40, but think about this for a minute. Believe us when we say we love a bargain. ![]()
