I doubt it's on the DS, but couldn't see if it was due to the water pump hose. Besides, the timing marks illuminate on the PS off the #1 cylinder. After some research, I see there are several different pointers, so now to figure which one.

I meant timing cover, not water pump. Seems logical that it would go there. Just making sure before I spring for the part.

I picked up a 69' Mach 1 for a project car awhile back and have it more or less ready for the road. It has a 70' BOSS 302 drive train. Broke out the timing light as my initial drive exposed some significant pre ignition. Much to my dismay, no timing pointer as shown in attached pic. While running the timing marks shown in the pic are displayed just a little retarded from where they're shown, so, I'm assuming there should be a pointer in that general vicinity. If that is the case, would it bolt to water pump with the bolts shown in pic?

I did talk to TCP yesterday. The guy I talked to recommended going with the 550# springs at least. So waiting on those along with spring compressor, spanner wrench, and thrust bearings. Just sorry I had to waste $104 dollars+ since they are the ones who recommended the 450's in the first place. Jim, I initially had the same issue you did with installing the assembled shock. The second time around I found that simply unloading the sway bar let the shock practically drop in place. Thanks for your input guys. Doug

I can do pictures tomorrow I guess. I have a '69 Mach 1 with a BOSS 302 drivetrain which I still consider a small block, certainly no more weight than your 351. I wonder if perhaps the coils may be mismarked. The coils compress 3 in., and I think I recall the instructions showing a 2.55" max. I like the installation, but just confused with the numbers. Will call TCP in morn I guess. Both side are identical. Going to disconnect the sway bar and re-measure in morning too, and see if that makes any difference. Glad yours is working for you, so still have hope on mine. Doug

I ordered the TCP bolt in coil over conversion kit with the springs they recommended (450#). Installed it all and it went fairly easy, the hardest part getting the welds off the upper spring bucket. Dropped the car and started measuring everything. First off, the shocks were on the bump stops. The ride height this way was within tolerances, but I didn't like the fact that it was already on the bump stops. Disassembled everything and took the bump stops out and reassembled again. Now, the ride height is out of tolerance per their instructions. Using their guide lines, to get the get back to mid range on shock travel I would need 633 lb springs. Seems abnormally high for a small block. Just wondering what spring rate some of you guys may have used to get proper ride height? I plan on talking to TCP tomorrow anyway but thought I would solicit your input. Doug
