Ok I have a really dumb question whats the difference between the vortec balencer and the regular one I assume the thickness to clear the crank sensor right?

Yup. The snout on the balancer has to be machined down the thickness of teh crank reluctor ring, so that the balancer doesnt stock out farther and mess up the pulleys

Best thing to do is go to junk yard and get balancer, reluctor ring, timing cover, coil, and dist from a junk motor at yard. Then, you have it all.
I got the whole pile for 35.00 and take it off a couple weeks ago.
It would probably cost that much to pay a machinist to trim off the balancer.

True, but if your balancer was balanced with your current rotating assembly you wouldnt be able to switch. Plus you cant buy Hi-Performance balancer.They are all standard OEM 8in. It did cost me 35 to get the balancer done. Apparently where you live there is alot of cheap places as every place around here wanted 20 for the balancer and upwords of 50 or more for just he coil and ig module. The going rate for a used Vortec distributor over here was 150 bucks.

So what would prevent someone from running some sort of DIS like the CNP on a 4th gen instead of the Vortec distributor? Just the cam sensor?

Right, do not use a fluid damper for a performace motor. I can link you to a good thread on the subject if there are any doubts.

Couple of questions for those in the know? Looking at the computer on the pictures that Mikos1980 kindly posted it looks as if the new harness will allow the 411 computer to fit in the same spot as the old TPI computer. Is this so?

Also with the new harness I assume the firewall plug for the main harness will fit in the same spot as the old TPI plug even though it has more wires?

Just trying to gets things squared away in my mind. Thanks guys.

The ecm will fit up there with no probs. As for passing though the fenderwall area. Its through there but the square snap in piece behind the fender doesnt work anymore. I dynamatted that area to cut down on noise and and water that may get up in there. As for the connector on the firewall, you use your stock one. You have to merge that area of the orig harness with the new harness.
----------
I'll try to get more pics this weekend.

Guys.... Let me know what you want pics of and I'll get them. Also, when I get a new harness from Mike for Justins car, I will show you how to merge them together with the stock harness .

That would be great to see - especially the parts where they actually merge. Is that at the firewall connector, under the dash, or ???? (shows how much I know about doing this conversion, huh? )

I posted the cal in zip format on the other thread if anyone wants to look at it. You'll probably need TCII.

I cant wait! I have almost all my parts for this swap. My harness is being made as I type this, and my O2 sensors are on the way! All I need now is a set of plug wires, a knock sensor....I think thats it!

You better believe Im driving to Ohio for this swap as soon as weather permits! I cant wait!
----------
also, does anyone here have an extra TBI harness that they want to sell cheap? I need one to hack up for my 411 swap

Im interested in doing this swap, but Im wondering about my TCI Super Dampner? Mkos1980, what exactly has to be done to the dampner to get the crank sensor to work? You mentioned machine work? I guess a pic would be great. Im using a ext. balanced 383. Thanks!

Also what are your thoughts on the 411 running a 520 hp 383 Miniramed car with 240/240 @.050 cam? Thanks again.

you put a reluctor rung behind the timing cover. Its job is to help produce a signal for the crank sensor. Obviously the reluctor ring is going to take up a little space on the crank. All you are doing is machining the width of the reluctor ring off of the snout of the balancer so your balancer will fit back on all the way!

I'm all for a tech article on this swap with pictures. I'm currently about two days behind in about everything at the moment. Then I came home yesterday to way too much snow and a snow blower that didn't want to run. Anyone have fuel injection ideas for a snow blower, LOL!

About the connector/grommet on the side of the car...I'd like to offer those with a harness, but the minimum order quantity is crazy. Now if we could get hundreds of these harnesses built....
