'the knock
finally decided that it is truly fixed.... I have no idea what part of the injection system was the culprit..... my current guess is the only sensor I never changed and wish I would have'the knock
sensor'. I couldn't find it at first, and gave up before I decided to look farther. That and the harness were the only things I never changed. runs now though.... and will let me drive it until a future motor swap. still on the fence with that one. MANY other things to do before I can think about it really. this only drives maybe 1000 miles a year when it IS running good, so carb'd will be fine for now. not what I want but keeps me from destroying it in a rage trying to figure it out lol. it did run AWESOME with the modded tbi for the few times it ran. Way better than it does carb'd. but is what it is now I guess.
If I get the chance in the future I want to do a 97-2000 vortech 350 with a size or 2 off stock cam and FAST fi. but with the house remodel, new baby, and a few things dealing with my aging parents, it may be a pipe dream...![]()

I found a complete running 97 5.7 vortech for $100. Going to slowly build it for the burb. Hopefully it's not in bad shape. As long as the block and heads are OK I'll be fine. Plan on a full rebuildStill no heater core work lol... Don't need a heater nowI found a complete running 97 5.7 vortech for $100. Going to slowly build it for the burb.

So...ditching the carb?![]()
Eventually. I'll have a carb style intake on it so I can run my carb at first. Goal is to build it with FAST efi in mind for the future. Going to stay mild'ish and build for the highway. Most of the torque down low, dont really care what HP does above 5k... That sort of thing. Wish I could sell my denali somehow.... Get done a LOT faster lol.

. Books for close, but the real market is way off. I've debated taking the loss and sticking the difference on a credit card. The $500 a month payment would kill the card fast. But I just hate the idea of doing it.Just because we're the same age dont mean we arent young dumb and full of stuff.Your only as old as you act right
I'm gonna be that way till a higher power puts the brakes on. You know, like if I end up with a wife or something

. Babies and women are expensive and time consuming..... totally worth it though 
. Feels good to know I actually own it free n clear again lol. With any luck it'll stay that way for a while too.

Flip side to that is for the same money I could have a 5.3/6.0 with a cam, tune and a rebuilt tranny......... I'll decide AFTER the denali is gone though.... right now my reasoning behind the vortec is its a simple weekend swap once it's ready. That'll help if it's my DD by then


I hate the carb lol. My mpg went to like 8 and even after a shop tuned/ timed it for me it still leaves a lot to be desired.... although I'm not really sold that they did a good job on it.Oh. Last time we talked I think you said you were going to leave the fuel system alone for a while.![]()
Is it? If you're figuring a full engine rebuild, and you hafta convert back to yet ANOTHER fuel system, with a foreign ECM, why not simply grab the newer engine? Is the Vortec ECM significantly easier to wire than the LS harness?
What JY is that?P.S. - my favorite CR junkyard will give you any engine in the yard + any of the related accessories you want for your swap for $350 if you pull it ($550 if they do it). That's probably worth the hour's drive for you to go pick it up.
They have at least a few 5.3 trucks in stock.![]()
