i want to switch the carbed 302 to FI. should i buy a junkyard motor complete or should i just swap it all. im not sure yet what year the motor in the car now is. but if i just swaped the FI parts obviously im going to need intakes, injectors, fuel rail, throttle body, computer, wiring harness, and maf. what else do i need. what all does it take to do. also are the 87-93 blocks full roller motors? thanks.

You'll also need the fuel pump (in-tank) for best results. You'll need an air intake, MAF, EGR spacer, Upper/Lower intake, fuel rail, fuel injectors, fuel pressure regulator, wiring harness, ECU and all of the little sensors here and there. Any reason you want to go EFI?

i have a fuel cell with the holley blue max pressure fuel pump and fuel press. regulator. i would just like to go FI for the power and the reliability. plus i want to run a vortec s trim. why should i not go FI. is there anything that would make this conversion hard?

Not hard but just expensive. Are you going to use all performance parts for the swap or stock parts? (injectors, u/l manifold, ma, etc. etc.)

I would stroke it and leave it carbed.

If you want, I have the stock upper and lower intake, fuel rails, 10lbs injectors, TB EGR, Computer, and bunch of other little stuff. If you want ill give it all to you for $250.00 plus shipping, I just want to get get rid of it its making a mess in my garage.

Hell if you want ill throw in a pair of stock heads for another $50

wont it be easier to make power FI. i was going to do mostly stock parts at first and then upgrade as i go.

Chris - I know it's an old topic but you're right, it's easier to make power forced induction. It's also easier to tune a carb unless you know somebody who works with the EEC-IV or you want to learn yourself. Any dyno shop can tune a carb though. There are blow-through setups for forced induction using a carb.

you dont need the upper and lower intakes. you can buy a kit which gives you the throttle body, wiring harness etc for $1000 cdn

It really all depends if its worth it to you... going EFI will be expensive but if you look hard and buy used you can come up with everything for a decent price. Also, fuel injected would be better for throttle response, gas mileage, etc.
