I have upgraded my ’89 LX hatchback street/strip with a Dart 347 stroker, forged crank with forged aluminum pistons topped off with aluminum 170 Trick Flow Twisted Wedge heads w/ 61cc chambers and Lunati aluminum rocker arms. I’ve changed from stock to a Ford F-303 camshaft. I have kept the old 65mm throttle body and 30 lb. injectors. Okay, what do I do about the timing? I think I’d have to change that by first unhooking the computer. If I'm correct or not, what are your specific suggestions?
