Hey guys, new to the forum and been out of the engine world for a long time.. I have a 1997 Single Cab Chevy with a 5.7 vortec.. Stock with a hypertech programmer, true duals, CIA, 3.42 gears with locker.. I wanted to upgrade my spider injection system but figured why not upgrade the intake to the edelbrock pro flo xt.. I am going to run a set of long tube headers as well with probably a black bear tune.. My question is which cam should i go with ?? i was thinging the LT4 hot cam kit.. I'm not looking for a super fast truck but decent gains with some awesome sound! Thankyou in adavnce for any help and advice!!

 

Lingenfelter Hydraulic Roller Camshaft L98 LT1 LT4 1987-96 TPI - Lingenfelter Performance

that would probably fit the bill well.

 

Thanks for the info! you think that's a better choice than a LT4 ? I emailed Comp Cams and he was saying with my computer a LT4 would be about the best. He said to give black bear performance a shout and see about what kind of tune they could do.. I had no idea these vortec computers would be that much trouble

Thanks again

 

Yeah the 96/97 PCM is an awful price of crap. Just swapping to a 411pcm and tune guys gain 45hp. Might consider looking into the 411 swap.

 

WOW!! That i did not know.. I was doing alittle reserch last night on it and its a computer out of any newer model or the 01-02 express van ?

 

Also what all do i need ? I see there is a place on ebay that sells reflashed to your vin411pcms
(12200411)


2002 Chevrolet Express Engine Computer 12200411 "Programmed to Your Vin" PCM ECM | eBay

they also sell the connectors for i think $20

 

Also found this.. comes with a tune

PCMPOWERTUNES.COM-411-SWAP

 

I would contact someone local if possible. Where do you live?

 

If you consider a new PCM, consider the EFI 24x solution and do away with your distributor. EFI Connection, LLC - EFI Connection 24x System

 

For Gen I truck engines, I liked the comp cams 260HR. You wouldn't want to go too much bigger for a truck with stock stall converter. Check out cam selections for comp cams at CamQuest ?
