ZZ4 camshaft
I have a 305 tbi 91 and a guy offered my a zz4 camshaft and i was wanting to know if i can use it in my 305. What kind of upgrade would it offer in hp and torque.

Just to say he wants $40 and said he paid $300 will it work with the computer.

well its a 91 caprice 305 tbi roller motor i think cast iron heads shorty headers hot plugs and wires.

So the cam will work with stock computer but will be best with upgrade valve springs?

and for $40 is it worth it i dont want a race car just more sound and alittle more power.

I dont want to change my rear gear and i just rebuilt my trans with a corvette kit and new converterand i dont want to change it.

I am sure i read somewhere that the 305 and 350 tbi injectors are the same but the fuel pump and computer gave more psi.

I dont have a problem changing the cam and valve springs i will do a port polish thin also but i realy dont want to change everything.

mafiacustomz 10-13-2012 06:26 PM

ya but after putting all that money into them i can just get a 350 tbi and computer.

mafiacustomz 10-13-2012 07:17 PM

you keep giving me all these high hp parts and $1000 converter and as i said I DO NOT WANT A DRAG CAR. I just want to know if this car will work with my computer and if my car will run with this cam. I just want alittle more hp and sound their are other people running this cam with tbi and stock parts.

mafiacustomz 10-13-2012 07:44 PM

I dont expect much from this 305 tbi as i said i dont want a race car i just want sound and alittle more hp.

Online the 91 caprice 305 tbi is rated at 170 hp if i can get it to 200 hp i will be happy its a show car not a hot rod, drag racer, street racer, ect...

I dont have a attitude with you im just telling you a 3000 stall in a show car not worth $500-$1000.

i would never change my 700r4 for a 200r4 and you keep giving me transmission and rear end.

I dont care if its all bark and no bite i want bark so im getting the cam and ill go from their.

mafiacustomz 10-13-2012 09:48 PM

they do the lt1 cam swap all the time in thes motors which is
DURATION 211 220
LIFT (1.5)492 .492
LIFT (1.6)525 .525

and the zz4 cam is
Duration 208/221
Lift .474 .510"

which means the zz4 cam is smaller thin the lt1 cam that is done all the time on tbi cars with none of the mods you keep saying.

mafiacustomz 10-13-2012 11:02 PM

well i dont have a rpm gauge but it will spin all day long but here is what i want to know will this cam work in my car run and drive with the computer.

Yes or No
Buy or Dont buy
better thin stock/wont do anything to the 305

Dont give me a parts list.

mafiacustomz 10-14-2012 11:01 AM

So what will it do to my car no gains in hp or sound and no power at the wheels.

On the other hand i will get alot better sound some power and more hp.

Its not making any sence to me how a bigger cam with 3 different seperation angle is going to make that much of a difference.

Yes i will need to add more fuel which a 350 chip will give easy but it will run and sound better thin befor.

mafiacustomz 10-14-2012 01:59 PM

ok so is the zz4 cam worth $40 should i buy it and resell it and get a lt1 or lt4 camshaft.

mafiacustomz 10-14-2012 03:41 PM

i would also like to add the guy said the cam came out of a 80's camaro with the tpi 350 that is a zz4 right?

techinspector1 10-14-2012 04:08 PM

F-BIRD'88, you have way more patience than I do.

mafiacustomz 10-14-2012 05:28 PM

ok ill get the numbers off the cam and find what it is and get back to you.

Any cam that idles the way you want your car to is going to make your car a total dog that is nothing but a big PITA to drive unless you do the things F-Bird '88 has been trying to tell you. You really should listen to him, the guy knows 305's.
