I have 1986 Camaro and intalling a 5.3LS (bigger LS7 cam later) out of 2011 Truck. It will be my weekend bracket car and may drive around town too. If I go carburetor route, the intake, ignition & carburetor will run be about $1,000. Also, LS with carb setup will require a new after market hood and I would like to keep my stock hood because.

If I go fuel injection route, the car might offer better driveability, fuel economy and the cost may be a wash. Also, I am a tight budget because I also have 1963 Nova which I am working on too!

What is the most cost affective option. By the way, I am very computer savvy if that helps.

1. Keep my existing ECM and have it reflashed? What happends after I install bigger cam (LS7)?

2. What is the cheapest aftermarket ECM (self learing) ?

Thanks

Why not use a factory ecu? Running the stock fuel injection isnt going to cost anymore than running a carb and to me the whole reason to do an ls swap is for the great FI.

I would love to use stock ECM if i can.

Can I make it work with TH350 and 3000 stall converter?

What happens with LS7 cam or other after market cam?



Thank you

Your tuner will most likely tell the pcm its a 6 speed car and just let the th350 do its own thing.
