advanced timing on my W200 camshaft
 

Hello,

I am currently rebuilding my ' 318 76 W200 engine. I bought a new camshaft (Sum-6900) for more torq. I have a performer intake and a edelbrock 1406 carb with headers.
With the timingset i bought i can advance or retard the cam compare to the crankshaft. I am planning to advance 4 degrees to add torq a low RPM .
The W200 4X4 (ex us-army )won't be in the high RPm's .
Is this a good idea and is 4 degrees a good number

Hope you can give me some advice

I usually go for 2° advance on most applications just too compensate for timing chain stretch.
how big is the cam?

Is this your cam? https://www.summitracing.com/parts/sum-6900/make/dodge
I don't think it needs to be advanced more than 2° it should work good straight up.

Yes thats the cam so 2 degrees? With the new chain there shoud be no stretch

New chains always stretch, the 2° may or may not be enough to compensate, it's just what I do.

I use MOPAR performance off set keys ways to do this. I have the mopar engine book 8th edition. I have a 360 I did the 4 degree BTDC so the cam will come alive before 2500 rpm and the torque at lower rpm, basically for towing and hauling.

I myself would just run it Straight up.
Note: you will gain more just by going with a 0-Deck pistons on your rebuild.

just my 2cents
