![]() ![]() That's more than GM claims, with peaks 100 rpm lower than advertised. With the timing set to 34 degrees (36 degrees produced the same power), the jets at 70/76, and an electric water pump in place, the HT383 overdelivered on the dyno, spitting out 338 hp at 4,400 rpm and 444 lb-ft at 3,400 rpm. We were surprised to discover that the HT383 comes with both a partial windage tray and a full pan baffle, so in back-to-back tests, the Milodon unit didn't help us out this time. We also opted to upgrade the stock oil pan with a Milodon claimer pan that has an integral windage tray, because we've found them to add a few horsepower. You'll need to provide a carb, ignition, and headers, which we did with components from Demon, Pertronix, and Hedman. Your new HT383 will come out of the box complete with valve covers, a timing cover, an oil pan, an iron water pump, an 8-inch harmonic balancer, an auto-trans flexplate, and a dipstick. ![]()
