Timing should always be set without vacuum hooked up. Initial timing should be around 12-15 BTDC at idle - around 24-26 BTDC at 3000 RPM's - and around 36-38 BTDC at 3000 RPM's with vacuum hooked up. There's (3) stages to timing on sbc:
10 degrees initial
10 degrees mechanical advance (the weighted springs in the distributor)
10 degrees vacuum advance These will vary depending on carb/intake/cam setups. Hope this helps!
The lower the compression, the more timing you'll need. Could be up to 18 degrees at idle (42 degrees total.) I'd start at 38 degrees total and go up and down a little at a time until you find the best performance.
That cam likes compression. The more the merrier. At least 10:1.
Change the following components to high flow/performance; intake (K&N) , exhaust manifold (Edlebrock), catalytic converter (Edlebrock), exhaust (Edlbrock), and add a NITROUS kit (NOS,Venom, Edlebrock) ! This should add 100hp or better (W/nitrous) and run between 2-2.5k.
No.
The firing order is the same.
NO, Not even close.
look on the intake manifold it will be stampes into the manifold cast.
On a small block Chevy the distributor goes through a hole in the intake manifold. On a Pontiac the distributor goes behind the intake manifold.
The intake manifold.
There is a tapped hole next to the distributor hole in the intake manifold.
WITH 4 BBL CARB (VIN T) 225 HP, 295 LBS TORQUE. WITH EDLEBROCK ALUMINUM HEADS AND INTAKE MANIFOLD ABOUT 300 HP.
Yes you do. The distributor must be removed.
There was only a visible cam sensor on '98-2001 Explorer 302's. If you have a distributor, your cam sensor is in the distributor. If you don't have a distributor, it is where the distributor used to be on the front of the intake manifold.
Back of the block, behind the intake manifold.
