Is it worth it?

[FMG CAMARO]

I am looking to add fuel injection to my 1968 camaro. It has a 4 bolt 350 with a 2 piece rear seal. Will a fuel injection setup from a 1994 caprice with a Lt 1 work or are these the newer 1 piece rear seal motors? If it will not bolt up to my existing engine are the early caprice Lt 1 motor worth building up. the reason I ask is because I can get a 1994 caprice cheap from a friend. I wont to go the fuel injection route for as cheap as possible. Any info will be greatly appreciated. thanks!

The LT1 setup, IIRC, will not work due to cooling system changes. The early LT1 motors are worth building if you want to stay inexpensive.

How much horsepower does your car currently make ?

How much do you want it to make ?

How much HP affects greatly which systems you can run.

My motor should be making 330 - 360 horsepower at flywheel. I am getting it dynoed on June 2nd. I will have an exact number then. I would like to add a supercharger in the future when funds permit. If I am going to spend $700 plus on a blowthrough carb I would rather put that money towards a FI setup. I saw a edelbrock FI intake with monoblade and an elbow. What system would this be and how much would setup like that cost.

A supercharger will push your motor well above your current HP, assuming your motor can handle it. Do some research to determine if your motor is in good enough condition to handle boost, and if not, ensure you're willing to spend the extra money to get the motor ready to handle it. For a boosted application, you do not want high compression. Also, a forged crank and pistons, are a good idea, along with higher pressure valve springs.

TBI injection systems start at about $1,500 retail. They're not the best injection method, but can work fairly well if setup properly. MPI systems are better, and start around $3,000.

When injecting, other extras are needed like a fuel return line, better fuel pump, some systems require a fuel pressure regulator, etc..

A good tune on such a custom application will cost around $500.

For turbo boosted applications, a wideband O2 sensor and AFR gauge is highly recommended. I imagine it would be for a supercharged application also. That will cost around $500.

I'm probably forgetting other recommended items.

Supercharging plus fuel injection, done well = large $. Plan it all out with a budget before you leap.

A good budget way to go might be to try a junkyard TPI system. With good heads and cam you can make the 330 HP and 400 lb feet of torque. Source one from a car with a speed density tune and your tune should be in the ballpark and drivable. Can be done on the cheap for a fraction of aftermarket systems if you don't mind the work.
