I want to build a motor for my truck. Its a 1999 silverado 1500 with a 5.3l Vortec. This is and will be my daily driver. So it will need to be streetable but still be a weekend racer on occasion. I was thinking a 383 stroker or will that not be a good street friendly motor? I will build the motor over time and when its all complete ill use a carbed intake to crank it up and break it in before i set it in the truck then ill swap all the fuel injection stuff on it. Can i get a set of stock heads from a junkyard have them rebuilt and ported and pollished to work on a 383. Will the stock computer work with a programmer. One where i can switch from a street tune to a track tune. Any advice or sugestions or anything is greatly appreciated. Thanks

So are you building the 5.3 or stroking a 383 and then buying a efi setup? Or are you wanting to make the 5.3 a 383?

And no a handheld tuner is not going to work even with the confusion I have read.

No im gonna build a motor and put it in the truck with the efi thats in the truck now

So what constitutes "EFI" for you, OP?

Dude, you need to take time to understand you engine and the power it is capable of. To get that engine to run with a carb is $$$$ as it requires a special intake and a whole different ignition system that is not cheap. Read before you wrench.

that's a difficult way to go about it... and a step backwards in technology. instead of dropping in a motor from the 70s...why not search out a 6.0L LS motor and drop in cams and heads? what kind of power are you looking for?

didnt know 6.0 had camS

So your going to build a 383 from a 350 block and then put the 5.3 intake and fuel system on the 383?

Please tell me I am wrong.

No that's actually What's he's saying

 

[mattdillon]

What wrong with that cant i just upgrade the fuel system by putting in a bigger fuel pump bigger injector and stuff if not tell me what i could do to have a fast street truck and fast truck at the track. Or what motor will swap in the truck with out swapping computer and woiring harness.

I said i would build a motor and put a carb intake on it to run it to break it in then put it in the trauck with the stock EFI intake and stuff

Why the fuck would u put a carb on it to break it in

 

[mattdillon]

I understand efi and carb motor i just dont know much about interchangeability of GM motors. I just want to know if i can build a newer model 350 based stroker with a set of worked stock heads and use the intake and stuff thats in the truck now
