I put a new crate motor in my 81 and it went fine, started right up. But, I am having a timing problem, I do not know what it should be! I took the computer OUT of the car and because of this I have replaced the carburator and distributor. The carburator is a Q-jet Stage 2. the car has an automatic transmission TH350C with a lock up converter, 2000-2400 stall.
Here is a list of the new engine parts:

Here is a list of all the information I have on the motor:
350 cubic inches 4.00" Bore, 3.47" stroke
8.5:1 compression ratio
300 HP @ 5200 RPM
368 ft. lbs of torque @ 3700 RPM

Engine Consists of the following parts:
* Block- part# 10066034, casting# 10066036
* 2 piece rear mail seal 4 bolt main
* Crankshaft -part# 93426651, Nodular Iron 1985 and
older flywheel bolt pattern
* powdered metal Connecting rods- part# 10108688
* Cast Aluminum pistons- part# 93422884
* G.M. High Volume pump, oil pump part# 12555284
* Hydraulic Flat Tappet Camshaft, Intake Lift-.443"
Exhaust Lift-.465" Intake duration @ .050 " -214 Exhaust duration @
.050"-224, lobe seperation-112. This can has a mechanical fuel pump lobe.
* Edelbrock performer EPS intake manifold ( Which I
removed and put on the intake from the original motor)
* Cylinder heads- part # 93438649, 1.94" intake
valve, 1.50" exhaust valve, 76cc Combustion Chamber, 7 bolt style
exhaust flange standard, 1985 and prior intake manifold pattern.
Permeter bolt style Valve Covers. This head is very similar to the old
#882 castings from the 1970's.
What I need is the suggested initial timing, rate of advance and total timing.

 

OK then, does anyone know where I may be able to find this information? I have already contacted the people I got the motor from, no help. thanks

 

Nice engine,but you use the same timing as other 350's
