I just put a new engine in and it seems to run like total garbage. Here is what I started with:

86 Camaro 305 TPI
Stock

Here is what I ended up with:

88 Camaro Engine (Roller)
86 Camaro TPI
Vortec Heads
Scoggin Dickey Intake
19lb Ford Motorsport Injectors
9.5:1 Compression Ratio
Roller Rockers
All New Sensors
Distributor and Coil out of an 88 (small cap)
Roller Rockers
Comp Cams 08-501-8 Cam Specs on cam:

Intake Exhaust
Gross Valve Lift 0.488 0.495
Duration At 0.006 Tappet Lift 264 269

When I first had it started it ran great!!! Then I checked to make sure that the timing was right and it was about 18 degrees advanced. The manual said that these are supposed to be set at 6 degrees so I changed it and it doesn't run well at all. Could this be because the distributor change. As I recall the HEI that came out of this still had some mechanical advance built into it. This new distributor doesn't.

Yes I know that part of my problem is that I am still running a stock 305 computer but I just wanted to make sure that I didn't shoot myself in the foot with any of my mods. Please help!!

 

Does your timing advance like its supposed to when you raise rpms? (check with light)

also did youput in a 350 knock sensor or a 305 knock sensor.

Whats the cam duration @ .050 and the LSA

 

I used a knock sensor out of an '88 350 (I remember reading that on this board awhile back!)

The duration is given at .060 and here it is:

Intake 264
Exhaust 269

Not to sound like an idiot but it's late and I can't think of what LSA stands for????

No, I didn't check to see if it advances with the light... I will check that tomorrow. Thanks!

 

Did you remember to unhook the EST wire on the firewall before setting your base timing to 6*?

 

LSA= Lobe seperation angle

 

AHA! Got it. Yes I did disconnect that wire before I set the timing.

The LSA is 112.

Thanks again.
