it was actualy only 216.5hp and that was with the timing set very quiclky by ear due to diagnosing a bad ignitor,as for mods on my healthy junk yard motor
I was using the smaller early damper, electric fan, 2.5 crush bent exhaust with no muffler, no air filter, 45psi of fuel? (I don't remember exact fuel pressure but it was pig rich on the bottom and lean on top) , home made fuel rail and a 240SX 5 speed,
I think the timing would have helped bring a few more hp but my nerves were shot it was a long day and almost didn't get dyno'd
it was kinda cool I got on the dyno right after a guy with a stingray vette and a fresh 355, he had more hp but I had more torque all that jaz about american v8 torque went out the window, the domestic guys actually stuck around to watch me run the lil old datsun (I don't think they believed me when I told them I expected 200-220 whp) they seemed real impressed with the numbers and I think a little more respect for little old datsuns
