I am putting a 1987 Linclon Town Car EFI5.0L engine in my 1967 hard top mustang and i need to know how many liters or gallons per hour fuel pump ill need. I would also like to know if it is possible to run the motor without the smog pump and cats. the motor is a speed density system not mass air.

Yes you can, get a 155lph. Its easier later on to convert to mass air.

do even have to smog test a car that old, in california we only have to smog '74 and later...

thanks for the info but will the engine run correctly with out the smog pump and cats

bmorrisj

you only need the air pump(smog pump) if your running cats...so if you lose one there is no sense in keeping the other...

yes, you can delete all the smog sh*t, so do it!! if you convert it to carb then you can get rid of all of the electrical stuff and emissions stuff such as the egr and pcv. you will gain a lot of power and if you do it right it will run just as good.
