I have more pics, Ill upload this afternoon....

But yes, the complete fuel log from the return system was used on the passenger side. The only drawback...the fuel pressure test port is gone, so I have a tee ordered to go inline I need this for my -4an Nos line....I have a walbro 255 so I know the pressure is good.

All the sensors from the l92 truck intake plug into the lq9 harness?

I see mention of a DRx adaptor plug for the tb,does anyone have a link they can post or pm me the info?

Ill be doing this swap with the TEA stg 1 l92's,Yella Terra 1.7 adj rockers,truck intake,and patrick g camshaft.Ive heard the stock truck injectors are 39 or 40# correct?
Thanks.

only sensor Im using is the MAP, plugs are the same, wires need to be a little longer. My truck intake came with TBSS injectors, same ones they use in 07 and newer trucks, not sure the rating, Im guessing 28 lb

Thats cooking for stock heads!!!

Did you even deck the heads or are they 100% stock minus springs?

What were you running before the head swap?These runs with nitrous?

stock heads.
Before the swap I had a cam, now I run a stock Z06 cam. All my runs were with 62/33 jets for 150 HP. So I gained .2-.3 1/10th's, even with a smaller cam. Plus before I had to pull the exhaust, with the Z06 cam you dont have to.
