green & black...sounds like you're looking at the injectors and the green ones are the stock 42# ers.

you won't be able to see your plugs just by looking at the motor...you have to remove the coil-packs first...which are located in between those green injectors.


like everyone else has said here...get it checked on a dyno and a 10# pulley is WAY too much for a stock bottom end.

 

Gotcha..but it may not be a 10lb pulley right..could be an 8..it measured 10 inchs but minus a few centimeters..it wasn't exactly dead on...but I've had the truck since Dec and have gone WOT alot and its all still in tack..

 

Well the guy that had it before might have done some work to the inside of the engine as well. So you might be fine

P.S. Did you take a look at my offer?

 

If you can wait till the end of April, I'll be moving to Cape Coral FL. About 2hrs away from you. I can scan it with a Predator to see how much timing you are running. But you really need to get on a dyno to get the A/F checked out.
An 8# lower is still too much on a stock block with stock exhaust.

 

Good try Chester


Bad Azz

I was running too much boost on a Built Motor and I hurt it, so please take what everyone is saying VERY SERIOUS. I am now on my second Built Motor and will never re-coop 1/2 my investment as a result. I thought having 25lbs of Boost was great, but it cooked my Heads (and Motor for that fact) in a little over 1 thousand miles. Now I run much less boost but added alot more power "the correct way", with Ported Heads, Over Sized Valves, Cams, Etc...

This is the current pulley I'm running (it's prob the same size you have)

This would be considered a large 8lb, I have larger than this one too, but I no longer run it.

You might want to start a new Post asking
"Are there any L Brother's that live near Davie, Fl"

Then simple ask if anyone can stop over or meet you to look at your truck and determain the size of the Pulley and what other Mods you have

 

Hey,

Home for me is in Davie, FL, but right now I'm in Orlando for school. I'll be more than happy to take a look at it this weekend if your available, as I'm coming down for the Indy races in homestead. Email me, or IM me....
