About 1.5 years ago, we assembled a project engine based on a B20 shortblock to test some new piston materials and skirt designs. One thing led to another and almost a year passed before the engine was put to the test during some extensive dyno work.

The combination used a bore diameter of 84.5mm and a lightly reworked and balanced B20 crankshaft, swinging Eagle stock-length rods and our experimental pistons.

We performed all the block mods we do for customers, including posting, boring, honing, decking, reworking the oil galleys and oil filter pad, align honing the mains, aftermarket main cap girdle, one of our modded ITR oil pumps, lightened ITR crank dampener, GSR/ITR windage tray, and last but not least, Moroso pan and pickup.

The top end of the engine utilized a GSR head with our oversize flat-backed intake and exhaust valves, Eibach valve springs, Crower titanium retainers, JUN3 camshafts, and our cam gears. The head was a three-day affair for me and it’s pictured as the “Grocery Getter” in the head modification section of “Components” at: http://www.theoldone.com/

The cylinder head package was also complemented by one of our massively reworked Skunk2 intake manifolds and a Russ Collin’s modified ITR throttle body at 64mm.

On the other end, the header was one of (Hy-Tech) John’s best efforts, with huge stepped primary tubes finally terminating in an under-the-car collector exit

The engine was installed in a racecar, and with no real time for tuning, run at a track, where the results were best described as dismal. The engine would leave hard, and then fall on its face, never making a clean run.
