Did you change the timing or have the time belt/chain replaced?

Does anyone know or have the timing specs for a 350 tpi

Not to be rude. But if you dont know what your doing, Don't **** around with your engine timing. It is very crucial that this is done properly. Messing up your engine timing can cause your pistons to possibly drive into your sparkplugs, causing engine failure, and possibly a blown motor.

no. if it is a tbi then you will need to set initial timing at 6 degrees before tdc and if it is a tpi then it needs to be 10 but i like it more on the 8 or less side. but by the book it is 10 degrees before tdc. also if you have the tpi there is the brown wire that needs to be un plugged (spoot connector) up at the firewall in the main harness on the pasanger side while setting timing. it stops the computer from advancing the timing so it can be set correctly.

please ask any more question you have i will be glad to help. i own 4 iroc-z28

I have an 87 trans am with a 305 TPI with an unknown problem

Check the knock sensor on the right side of the block,below the head,and above the oil pan.Check to see if it is plugged up good.Then check the wire all the way up to the wire harness,to see if it is grounding out on the engine somewhere.I hope this was helpful261213.jpg

A few things could cause this: one-if you replaced wires then make sure wires are in right order and if in right order then make sure gap is right on new plugs and/or they are on the right places on distributor cap, two- your right at timing being important but timing would be all the way through, three- the most probable cause is your fuel injection depending on cpi or TPI, I would run a fuel injection cleaner through it for about three tanks or run premium gas for about 5 tanks and that should clear up your problem. Hope this helps....

What is the timing set at for a 1991 Camero 305 V8 ?

Try 0 degrees. It should state it on the radiator cover, but mine didn't. I tried 10 advance and it started real hard. I think you need to disconnect the single wire terminal near the distributor/coil that sticks out of your harness wrap before you set timing and reconnect it afterwards. That's what I recall from my TPI car and this TBI car seems to have the same electronics. Good luck.
