That cam should operate from around 1200 -5500 rpm. it will pull hard throught the powerband but have nothing after 5500. a 2000 c0nverter and a shift kit will work wonders for that combo

i say go with a little larger cam i put one in my tbi truck that was a little bigger than that and it didn't need a stall at all but that 500 over stock stall will be almost unnoticeable if your going with that cam i say no stall that is a very small cam

That's a fairly mild SBC cam, I don't see any need for a higher than stock stalled converter. Here's a comparo that might help, In my old 85 Monte SS, I had one of the early ZZx 350 crate motors that I swapped a later model ZZ cam and intake into/onto to make for a smooth daily driver. IIRC the cam specs were 208/221 .474/.510 112, and I ran the stock 200R4 converter and factory .373 rear and the combo was an excellent match. (the carb was a big block feedback quadrajet, the intake was a lower rise dual plane, and the exhaust consisted of an Edelbrock TES, gutted cat, and Hooker Buick GN dual catback). I ran the whole setup using the factory PCM (or ECM as they were called at the time) believe it or not.

Before that I used to have a 71 Camaro with a 350 SBC, DartII heads, TH350, 4.10 gears, and a Comp 292 Magnum cam. The specs were 244/244 @.050 (292/292 advertised) .501/.501 lift, and a 110 LSA. Operating range 2500 to 6500. I ran a B&M 3000RPM Holeshot converter and it was perfect. Other goodies on that car included Hedman 1 3/4" headers, custom 2 1/2" dual exhaust, and believe it or not, I can't remember what carburetor I ran (this was back in 1987-88 when I was 17-18 years old so my memory fails me a bit lol). I believe that it was a Holley 750 double pumper though...I know for sure that it was a Holley.

The Camaro definitely needed the converter whereas in the Monte, the converter would have been good for was wasting gas money lol.

Thanks, thats the kinda info I was looking for. I have a friend with a comp cam 280H in a 355, he has a 80 malibu 2 door. That thing sounds agreesive, he is running a 2500 stall on a built 700r4. His car is the one the transmission I'm getting came out of.

I am going to pickup a 350 with 70K on it today, came out of a 76 van, supposed to be super clean. Also, a set of vortec heads with under a 1000 miles on them from a friend. I am pretty set on that 272 cam unless someone can recommend something better for the vortec heads.

I am wanting to stay away from roller cams for 2 reasons, one is cost, the other is the engine I found doesn't have the provisions for it.

The car already has a set of headers on it. It looks like it's going to be a personal test bed for summit parts, since it will keep me inside my $800 budget I gave myself. I am going to order all the following parts in summit name brand: 600 carb, dual plain vortec intake, hei distributor, oil pump, water pump, timing chain, cam/lifters, and gasket set.

Cool, sounds like a nice budget build I've noticed that the early 80's Malibu's have gained quite a bit of popularity over the last 15 or so years, I'm assuming due to their availability, affordability, styling, and mod-ability lol. My father has one (I think it's an 81 maybe) with a 406 sbc that runs consistent 10.3's with a best of 9.9 at I believe 137mph.

Be sure to keep us posted as the build comes along

I have always been a fan of the malibu 2 doors, el caminos, and the wagons. Since the first niece joined the family (I was 16), I thought it would be cool to have a wagon to drag everyone around in. My wife thinks the EL's and the 2 door malibus are ugly, but there is a nice malibu wagon around town, that changed her thinking on the wagons.

This car




Ours will either be the original factory charcoal metallic when done, or I might see if I can get deep dark blue (something like usabodyguards) to match the dark blue interior it has.



Oh, by the way, thats my new monster topper on the brown truck in the background. It's ugly, but ever so handy having the extra room inside.

Very nice, the Ralley(sp?) wheels really suit those cars nicely, that red wagon is sweet. The lines of the cowl hood are a perfect match also. I think either color choice you go with will look good on that ride. Now that I think of it, my pop used to have a red malibu wagon, and my great uncle had a beige one. They both had small V8's in them IIRC. I drove my uncle's car once and the headliner was laying on my head as the adhesive had come undone as all of those 80's GM cars did lol.

I am really hoping to either run some 17 inch torque thrusts or some of the wire mesh GTA firebird wheels.

The rear most section of the headliner glue has come loose, it is a seperate panel from the rest of the car

I picked up my 70K mile 76 Chevy Van motor tonight. Looks like either a quaker state motor, or the oil wasn't changed regularly. We will tear it down and get a good idea for what I found. Hopefully it's just gummed up. They guy I bought it from swears it only had 70K on the van.

I stopped on my way home and picked up my vortec heads. My buddy looked at the motor and said he would be willing to bet is a 4 bolt main because of a extra water port on the front of the block. Thinks I did pretty good for $300, since the motor is so complete you could add fuel and the thing would run.

The block turned out to be a 2 bolt. It also sat for a very long time which lead to rust in the 4 cyls. I sent the guy an email, he said to bring him back the short block, and he has a nice 4 bolt short block he will trade me. I guess I really can't complain.
