Hello there after many months expense and stress I am getting rid of my tpi setup and im going carb one quick question my car is a 88 with the 305 I am wanting to use a mechanical fuel pump will my cam be set up for this when I remove the little blanking plate on the block Thanks Ant

 

Should be.

 

You are aware you have to drop the tank to remove the old elec pump because the mech pump won't suck through it?????

So you may as well install a in tank carb elec pump while you have it apart and forget about the mech pump.

Or easier still , keep the TPI pump and install a bypass reg to drop the pressure down to suit the carb

 

Your factory cam DOES have a fuel pump lobe for a mechanical fuel pump behind the block off plate.



+1 You WILL need to remove the pump from the tank.



I completely disagree: My ;

DON'T put some other Fuel pump back into the tank and don't bother with trying to regulate the pressure. An OEM type SBC block mounted fuel pump will cost about $35 and if there's ever a problem you can pull it off and replace it in about 1/2 hour - and you will never need to lay under the car to get it done.

 

so many of the tpi cars are sitting in the local pull a part. complete. theres so much that can and will go wrong with this set up that its a wonder ANYBODY wants one. (and it appears no body does) as soon as some mechanic says the words "data logging" or "you need a lap top to tune it" they junk it and move on. sad really

 

Thanks for the input guys im going to use the mechanical pump with a feed to the tank no pump in there i want it as simple as i can im fed up of bad electrics and sensors And i agree rusty not many people are wanting the hassle of tpi im in the uk and a mechanic frined of mine has already converted 5 tpi cars to carb because the owners were fed up of problems and driving issues. It is a shame because i had another 88 years back a stock car and i had no issues at all my current one has been a pain to say the least.

 

The fact the cars are 25+ years old and most commonly still using the original parts they left the factory with has no bearing on the problem?
If owners were prepared to put a few quid into the their cars they would probably go another 25 years fault free.
But in the US at least , they buy a $1000 car and expect it to run like when it left the factory when new; there is a reason it is a $1000 car ..........

 

A update ive ordered my intake gaskets and distributor today from rock auto im ordering my edlebrock carb tomorrow .
