anyone done a Vortec 454 swap?
Well my long overdue project may have taken yet another turn today. I picked up a 2000 Vortec 454 and 4l80e trans complete with all wiring and computer this afternoon. Interested to see if someone has already done this swap.
Anyone know the specs on this engine????

It should look something like this when installed.

Well, yes…I am sort of in the middle of that swap now. Marine L29 EFI instead of automotive (C/K truck) L29. Less the 4L80E though.

Well Larry, I guess we are the pioneers for this engine here on this forum.

Re: anyone done a Vortec 454 swap?
After a bit of on-line research, I've discovered the Vortec 7400 L29 motor uses the same cam as the 502HT crate motor.

http://www.dieselpowermag.com/towing.../photo_09.html ![]() Since I do not plan to pull up stumps with this truck, I will definately be swapping in a different cam to bumb the HP up a bit. Not sure if I should just get the engine installed and running first, or go ahead and swap the cam while it's out. Anyone know how much lift the stock Vortec heads can handle before the valve keeper bottoms out on the guide?? Hmmm I've got a set of 781 heads I could use...

I know a guy who did this swap but carbed it he put it in his truck. Its a k20 '84 turbo 400 36" tires and six inches of suspension lift. He hooked it up to a pulling sled and it pulled 292 feet at a 300 foot track.

I've decided I will leave the engine stock for now and just drop it in the truck. I'll use the Headman Elite headers I already have, then get an aftermarket air intake setup and a custom tune flashed in the PCM. That should put me real close to 350HP with gobs of torque from off-idle to 4500rpm or so. The 4l80e trans with stock locking torque converter and a 3.42 posi rear end should let me get pretty decent fuel mileage and still have a lot of fun.

Re: anyone done a Vortec 454 swap?
I realize you are going with the EFI set up. I was telling you how much power you can get out of a completely stock motor.
