Engine Shots
The first shot is some of the new parts I received followed by the new Cobra short block, ARP beefy oil pump shaft compared to the stock one, Canton Windage Tray parts, tray installed with modifications for the stock oil dip stick tube assembly and the March alternator and power steering brackets.

Here are the latest shots of the engine after it ran it's first time. All that's left is to fine tune after the exhaust gets fixed. The shot after the engine run is the oil filter adapter at the block. I had very low oil pressure and found it to be cracked. Most likely when I tightened it. New one is on the way. No damage done. The last picture is my lower radiator hose setup. They are secured to the lower "X" member. The last picture is of the lost oil galley plug that wasn't installed at the factory. Now it's in and there's 70#'s of pressure. Also is the billet adapter I installed at the block for the oil lines.
I had a dyno run done in August of 2004. I kept putting it off but I had to get this done just to see what I had. The engine specs are as follows:
302 stock shortblock
FMS X303 heads
FMS "B" cam
FMS 1.6 roller rockers
standard oil pump
Canton windage tray and Road Race oil pan (7qts.)
Cobra intake
24# injectors
65mm throttle body
70mm MAF
stock distributor
As you can see by the chart below on the left, the engine with Cobra intake has about 282 ft/lbs of torque at 3880rpm, and 251 HP at 5034rpm at the rear wheels. I wanted this because I was changing fuel systems and needed a good baseline to compare each system. My old system was the Cobra intake with 24# injectors as listed above. I will take another run with the new Victor Jr. and "Mass-Flo" system from Quality Roadsters and post it here. You can read about the upgrade here:Mass-Flo Injection.

| Cobra Intake Dyno | Mass-Flo Dyno | Dyno Setup |
The chart on the right is the new "Mass-Flo" system from Quality Roadsters. Everything remained the same on my engine except: Cobra intake, fuel regulator, 65mm throttle body and 70mm MAF. Why, I didn't need them anymore. The "Mass-Flo" system looks just like a carburated setup, but isn't. The Victor Jr. setup gave me 258 ft/lbs of torque at 4391rpm, and 272 HP at 5961rpm at the rear wheels.
The Mass-Flo setup gave me 20.5 more peak HP at 927 more RPM. To me, that was more than I was hoping for. The torque dropped by 24.1 ft/lb, but also peaked at an additional 1051 RPM. So, the system is doing what I expected, carrying more torque and horsepower longer, as seen by the fact that torque peaks an additional 11mph and horsepower and additional 20mph. This should suit the stroker build just fine. I'll do another dyno test after that's completed and broken in, which should be next spring.
Although the Cobra intake was doing it's job, it was also choking my engine. The shorter runners on the Victor Jr. are giving up the low end torque but I should see an improvement after stroking. Am I happy, you bet I am!
The timing is set at 12° and fuel pressure is 40psi. It is set the same on each system so a comparison will be equal. Distributor cap, rotor, spark plugs and wires remained the same so there won't be any advantage to prove otherwise. I felt this way it would definately be a fair comparison.
The next step for this is a 331 stroker. I'll most likely go with some Trick Flow items.
