Thanx KULTULZ I had time to look up that site it pretty much told me all I needed to know but I still have a couple of Questions left. Where can I find one and it better, in your opinion, than a newer TBI? Also, was 92' the last year they made them? <img src="graemlins/evil.gif" border="0" alt="[evil]" /> <img src="graemlins/evil.gif" border="0" alt="[evil]" /> <img src="graemlins/evil.gif" border="0" alt="[evil]" />

Here is another -site- that will give you a brief history of TPI.

Yes, TPI is much more advantageous than TBI.

TPI steups are readily available on e-bay and on message boards. There are several companies that specialize in TPI and conversions.

If I was a Chevy freak...I would definitely use this system on the street. I prefer the earlier system with MAF, but the later system is more easily adapted to other chassis.

Anything else, just ask.

KULTULZ, Here my story. I've rebuilt a 1967 Camaro. Tip Top shape but I left the orginal 327 in it after my dad and I did some work to the 327 to get it to run. I'm 17 and have had it since I was 14. It was my money so at the start I just wanted to get it on the road. Now I'm ready and have saved up for an engine and want to go fuel injection. I want at least 15 to the gallon but also want about 475hp to 500hp out of this motor. In your mind do you see this happening with a TPI. And why in the world do they not put these injection systems in more sports cars?Camaro for example(98-02). I KNOW THIS IS LONG BUT PLEASE READ.

It will take more than fuel injection to get to your wanted HP level, but yes, TPI can get you there.

The one site I gave you has a tech source of texts concerning TPI and swaps. You need that technical information to understand fully what you are wanting to do.

Wire and ECM kits are readily available for earlier conversions.

TPI, when first introduced, was meant for engine torque and low RPM's on the street. But the system can readily be modified to compete with a carb. setup.

Just here recently where I live, the local speed shop had the intake manifold and runners (used) for fifty dollars. So finding a complete setup will not be that difficult.

Do you think I can get 475 Hp with this setup, b/c I know I can get it with a big Dumper of a carb. and quite a bit of modifactions on a 350. I have already discussed it with many people including my dad, he is a mechanic at a Chevrolet Dealership, He thinks I could get the HP easier with a carb. but my whole purpose is to maintain a decent amount of fuel milage. I'm also tryin to do this my self, do you it is all that hard to put a TPI on with just a manual and freindly suggestions?

Your dad is correct. A carb setup will give you the HP much easier and cheaper. But the end result with FI is much better driveability and fuel mileage.

You already have the battle won actually...your dad is a GM service tech and his ability to get replacement parts cheap. I bet he will even help you turn a few wrenches...
