Hey guys i'm new to the forums but not to yota's. This is my 4th truck, got some plans for it but gotta get it running right first. Anyway it's a 88' toy pickup with the a blown 22re. I rebuilt it with .020 pistions, block decked .010., new engnbldr street rv head with oversized valves and a 261c cam. I got it back together and am having trouble setting the timing. I lined it up to tdc, set timing chain on and lined all that up. Crank keyway is at 12:00 and cam dowel at 12:00, cam timing dot is at about 11:55. I lined up the distributor rotor to 12:00 and stuck in distributor, the rotor went ccw to line up with #1 on the cap. The problem is i cant get the ignition timing correct. I jumped out the diag. connector with a paper clip and the idle drops. I set the tps so i assume that is working. I then proceed to put the timing light on it and with the distributor fully rotated clock wise (retarded), i can get the timing to hit 5 degress btdc. It wont go any lower. Seemed to run fine in the 10-15 degree range?. I thought i had the distributor 1 tooth out but if i retard it one tooth i have to crank the distributor fully advanced ccw for it to barely hit 0 degress. Its more in the atdc range. It runs way late and the exhaust starts getting pretty hot. It set the distributor back to the orig location and currently have the timing @ 5 degrees. Anybody have any ideas? Do i need an adjustable cam gear for this thing since the block was decked .010? I'm assuming i lost 1-2degrees or timing from that but could that be my problem? Sorry for the long post but this truck is driving me insane. It just doesn't seem right to have the distributor fully cranked to get the timing to the factory setting. I've searched and googled. I found a few people with the same problem but have not found an answer.
