You bought a V6....
GMCfag 06/16/14(Mon)17:47 UTC+1 No.10494912 Report

I didn't buy it, it came out of my mothers old truck that she bought brand new years ago and gave to me. My dad offered to front the cost of parts, vatting and everything to rebuild it for my high school graduation 3 years ago so I took the offer bought an extended cab body with a blown 2.8 in it and swapped engines/transmissions

also, what is the problem with having a v6?

Misindexed distributor. I guarantee it.

As really the only come back people have in America, a V6 engine is just as capable as any engine.

You're 180 degrees off. Happens all the time to people who don't do this shit st least weekly
GMCfag 06/16/14(Mon)19:47 UTC+1 No.10495458 Report

it was 180 off at one point, we took the timing cover off turned the crank and cam to tdc marks on the gears and slapped it back together, trust me when I say that the timing is right all except for a few degrees of adjustibility on the distributor to get the retard/advance tuned when we get it to start.
and yes the spark plug wires are on the right terminals
1-6-5-4-3-2 is the firing order for informational purposes

in my opinion certain v6's sound a damn sight better than some v8's but I really like the sound of an old cast iron horse running wide ass open

You know there's a difference between cam/crank timing and ignition timing, which is what I'm referring to, right?

To be even more specific, the distributor has been stabbed with cylinder one on the exhaust stroke, not the compression stroke. Remember there are 720 in a complete cycle so TDC will appear twice

oh, wait your talking about the distributor being set at the #1 cylinder not the valves in relevance to the crank? if so then yes, I changed the position of the dist. when we redid the timing
when the cam is turned to tdc and the crank is turned it should be correct because that would mean true top dead, am I correct?

>cam gear shit

Yes that would be tdc on the compression stroke for cylinder one. If the distributor was stabbed at that time without rotating the engine then it should be close.

Pull the number one plug, put your thumb over the hole and bump the engine until you feel air being blown out. That's generally in the 30-40 degree btdc range but close enough for checking. Then pull the cap up and the rotor should be close to the number one post.

Time to go. Won't be back for many hours
