thanks... I can drive it any where and I haven't even tried to pull weight out of the car.
funny thing is ... it idles so good people think I am running a stockish Gen1 motor.
When I pop the hood most people say ... "oh you running a 350"
I joke a say a new model ford with no Distrubtor... LOL
They mostly cant tell. Coil packs are a dead give-a-way to me.
What I would love to do is... add a Blow thru single turbo... That would be WICKED !!

I do have ported heads too, but I have had a 650 mighty demon, 750 speed demon and a 750 mighty demon on mine. Out of the 3 the 750 speed demon gives the best throttle response and pulls the hardest. However if I decide to drive mine more often I will put the 650 on because it runs good also I think it just leaves a little on the table.

Here's a more recent pic of my setup.
New additions
Norris catch can for PCV system
50cc acclerator pump for carburetor (solved off idle stumble)
15 degrees base timing at idle vacuum advancing to 24 degrees at idle
28 degrees max timing WOT, 40 degrees max timing cruise
72 primaries, 76 secondary jets with a 6.5 power valve gave me 14.6AF at idle, 12.8 at WOT, and 13.6 at cruise
I also installed a FAST dual wide band 02 sensor setup which logs and everything

I got mine from Ebay for $80 just a standard holley 750, 4160, 3310-2.
metering plate to metering block conversion kit - $35
electric choke - $50
rebuild kit - $50
spring kit - $12
50cc accelerator pump kit - $40
Holley Adjust-a-jet metering blocks (infinite external jetting) - $100 from ebay ($200+ new)
I good carb will cost around $400 at minimun to get it right for your setup.

Are folks mounting their 6010's on the engines? Shawn I've read your posts about the 6010, I'll definitely look over them once I get the parts. I want to try a carbed LSx for my '51 Merc, just because I never did one before.

I temporarily mounted my 6012 box on the fenderwell. Didn't want to shorten the harness until I was sure everything works. I don't like the hard plastic convoluted tubing they ship with the harness. Plan on switching to fiberwrap when I move the box under the dash.
My timing set up is like Shawns for now. Adding the vacuum advance really helps it start easier. I bought a USB to serial converter off Amazon for $10. Works great.
Have a Holley 750 HP, mechanical secondaries, 72 primary and 76 secondary jets. Had to increases the accel pump discharge nozzles and use more agressive pump cams to get rid of the stumble, but so far haven't needed the 50 cc squirter like everyone else did. Mallory Comp 140 electric fuel pump with a return style regulator on the firewall.
This pic made me cry when I finally got the build this far.

I know on mine, it is a 402 Ls2 with 11:1 and on the dyno, we were having some vacuum issues and the larger the carb I put on, the less backfeed we would have. I ended up putting an Hp1000 on it and it made the most power with that. This engine is a thirsty bitch.
We will see with the new setup. upping the compression and more radical cam, super victor and putting a vacuum pump on it. With the new ring gap and compression, I think the ve will be around 90+%, so it will probably end up being an HP850 or worked over HP750.

need carb verses computer info
i have a 5.3 i got from a friend. i got everything but the computer. im putting it infront of a 200-4r. im thinking about running a carb instead of injection to make the computer programing a non issue and to fix the trans kick down problem. is there anyway i can still run coil packs with a carb? if so or if not what all would i need. thanks.
