Ok I have a 86 Z with a tired 305 carb and auto trans. I do not have to drive the car every day but I am looking for a car that is strong and just runs good. I have a 91 350 TPI with ecm and wires. I have been pulling a brett favre on what to do. Here is what I have been thinking. Just buy the stuff I need (fuel pump, fuel lines and misc) to complete and put the TPI in the car. I was also thinking since the 350 is on a stand now go ahead and freshin and cam it up. Idea two is to take the TPI set up off and go with a intake and carb set up with a freshin and cam as well. The money seems to be close to the same, so it is just a matter of what to do and what would be better????????

 

Putting the 350 under the carb system would be less work and money. You wouldn't have to change anything you don't have. You could do it for intake gaskets (and if you're changing the cam, you'll be doing intake gaskets, anyway).

You could sell the TPI set-up for more than you could get out of the carb set-up. The TPI would get a little better mileage, but you wouldn't have to be as careful with the cam with the carb as you would with TPI. No particular difficulty tuning the carb to the 350, but if you put a different cam in with the TPI, you'll likely have to do some PROM tuning.

Either way, the 305 exhaust is inadequate.

 

I am leaning on the carb set up. The good thing with the exhaust is that it is all new 3" with a flowmaster. I was thinking headers as well.

Thinking of headers what are a good set that do not cost a arm and leg and are easy to work with??
