ok sorry its been so long been busy. so I ordered the dekoda digital vss adapter and put in a 2700-3000 rpm converter. Calling March Performance tomorrow my question is is there an adapter for the new style a/c to my old lines or do I just need to get new lines ?

I am doing a rubber bumper over to a aluminum 5.7 + T56.
I am going with a C5 fuel rail with a C5 intake (for now). The fuel feed line enters the rails on the passenger side. That way you can just connect the factory hard line to a flex line, then plug it into the fuel rail. It makes it a little easier to setup.
Also, the kit the guy on corvetteforum sells, is just the bracket. You need to buy a compressor designed for a serpentine belt system. Pretty common on 3rd Gen F-bodies and it allows you to use your stock hoses/connections. He also sells the transmission cross member if you use a different transmission like a 700r4 or 4L60e (recommended for street use with the 4th gear).

Ok I have the ls1 intake manifold with the single driver side fuel inlet. Im assuming its the inlet as it is the only one my question is is that a regulator on there or do I need to get an external one.
Will post pics of the March Performance kit soon installing this week

The LS1 fuel rail only has a dampener, not a regulator. Truck rails with a return have a similar appearing regulator.
You will need a regulator, ie 02 corvette filter/regulator, or a pump assembly that's internally regulated, ie. 99-02 f body.
Oh yeah, on the passenger side fuel feed comment above, you can flip any fuel rail around to feed from either side.

Cool project.
Your last picture is not an F-Body pan. It looks like the muscle car oil pan kit from GMPP (aka H3 pan). Summit and others sell it but they are deeper than the F-Body pans. Good pan for a good price, just make sure it doesn't hang below the cross member.
On your earlier question about the transmission, it doesn't matter which flexplate you have with the engine. Both the dished and flat ones will work, but you will need a crank spacer, longer flexplate bolts and to elongate the holes for the torque converter by about 2mm.
A few options...
GM's solution but requires 6 new bolts.
Bolts for above...
Another solution that doesn't require bolts, but not as flexible.
There is a third option that was around $75 or 100 that had a flexplate, spacer and bolts but I can't find it.

Russell Quick Disconects One more bit of bad news, that picture of the fuel pressure regulator (fpr) your blue quick disconnect (qd) is the Russell new style with the positive metal screw on retaining lock which is the good one, but your 2 black (qd) are the russell old style with the plastic retaining locks and there are quite a few people that have had them come loose under pressure which results in about 60 p.s.i. of fuel being sprayed on surfaces that you dont want gasoline on (fire,fire,run,run) and there a the people that say they are fine. Me personally I dont like to skimp or take chances with gasoline apraying @ 60 p.s.i. and if the old ones were fine I dont think russell would have re-designed them, somewhat good news they are only about $15.00 each through summit or Jegs, I think the part numbers are 644113 for the 5/16 black fitting and 644123 for the 3/8 black fitting, they also come in blue but it is another part number. Good Luck

I too got a used LS1 intake manifold to put on my 1980 Vette. It didn't come with bolts either.
Ended up ordering them from McMaster-Carr for $10. Same as the hex head ones you see on eBay for $30. Also ordered a bunch of other metric bolts for accesories etc.

Is the alternator plug on the truck harness diff from the one on a Corvette harness ? The alternator that came with the march performance kit wont plug up with the truck connector ?
