I'm swapping in a 350 right now and wanna get some of the engine work done before I drop it in. I'm looking for a good street/strip cam in range of 1500-5000. Also lookin for advice on an intake. U guys rule, all help appreciated.

 

Read My sig for the cam....................Edelbrock makes a good intake for you, I think its a preformar RPM TBI, but do you have a aftermarket hood for the clearance?

 

No I do not have an aftermarket hood for clearnace, will I need one if I get the Intake? Also I saw you got a crane powermax 440/454 does this cam sound lumpy on idle, and how does it do on gas?

 

first off, we need more specs on the motor.

what heads.
what the CR.
what tranny? what stall if an auto.
what rear gears?
do you need to pass emisions?
can you burn your own proms?
is the 350 roller or not?
what manifold do you plan to run?
do you have headers?

 

the motor is out of a '92 truck with TBI.
-stock heads
-stock cr
-700r4 trans. with stock converter - want to get either a b&m tork master 2400 or 3000, and a trans go shift kit
-stock rear gears, i think they are 2.73 - want to get 3.73 gears
-no emissions
-cannot burn a prom - want to get a hypertech chip or a cprice cop car chip
-not sure about roller motor
-stock manifold - want to get the edlebrock performer for the TBI, and get a 454 TBI with ultimate mods done to it
-no headers - want to get shorty headers, full exhaust no cat

Let me know if these are good choices, if not plz help, still new at this, thanks for all your help and if u need to know anything else let me know.

 

as a friend of mine said "throw those heads at the nearest ford that drives by!"

 

No the cam does not LOPE and you won't get a TBI to lope due to the lack of vaccume. The Map has to have vaccume to run right. But that cam does do real good for me, its got a 117 lobe seperation I think. Gas milage is good about 15 or so, but I have 3.73's and I drive around everywhere at about 80, engine turnin around 3000. I have the same heads as you, With mild port work done, granted these heads are junk but its all I had, Part # for cam is in my sig. AND BTW I ordered mine from summit and they said my cam would not work in my car, COMP said the same thing said it was tooooooooooo big, HA!!!!!!!! DID I PROVE THEM WRONG

 

I was looking at your cam and the crane powermax emission legal one #114132, they have same duration, the same rpm range, and the same lift, both include lifters, whats the difference? The emission legal one says it is good for computer controlled cars. Idrag, have you run your car with the 3.73's? If so what's your time, I like your setup, sounds like a mean 3rd gen. Thanks for the help everyone.

 

Since the engine came out of a truck, I'm pretty sure that it has a flat tappet cam. So you should be able to replace it cheaply (under $100). Don't go higher than 203/210 degs intake/exhaust though, because anyhting hotter than that and it will NOT run well without serious chip tuning. The milder the cam you choose, the better it will run at all speeds with a factory chip.

A 3000 stall converter is going to be too much, and IMO so is a 2400 stall. You shouldn't waste your money on those converters until you have an engine worth that kind of expense. The same comment can be made for gears -- they'll cost you a lot of money, but they won't make the car that much faster... but engine mods will. If you want to spend money, spend it on the exhaust --- it's the biggest restriction in an Fcar.

IMO do not buy the Hypertech chip -- it's benefits are just hype. Get a 91-93 copcar chip from the Caprice LO5 9C1, it's the best starting point and low cost, and you can make the engine run well even after the cam swap, if you raise the fuel pressure slightly using the FP mod found on the Tech Archives. Keep the stock TBI but do the ultimate mods on it, and get the injectors from the same copcar you get the chip from. You aren't going to be making enough power to require the airflow of the 454 throttle body, so don't waste your time or money with that. Stick with the factory TBI but do the rest of the mods to it.

Replace the fuel pump with an 85 Vette pump, at minimum.

The intake manifold should be replaced, but you can keep the stock manifold for now -- just try to do some mild porting on it first (radius the sharp corners on the INLET side of the runners, down in the plenum under the TBI). Don't repeat the mistake of some many 3rd genners by running an open air filter. They look nice, they make more noise, but they are not as good as the stock air cleaner with dual ducts fed by a source of cold air. Vizard makes the same point about the benefits of a good cold air system.

The copcar LO5 350 was rated at 195-205 fwhp @ 4400 rpm and 300 fw ftlbs @ 2800 rpm from 1991-1993, and it's been shown to make roughly 230 fwhp and 320 fw ftlbs, based on track timeslips in a Caprice, with only an exhaust upgrade and a better air cleaner (Caddy elbow, fed by PVC sewer pipe & cone filter).

If you replace the cam on the truck engine, and if you do sensible things (like the above suggestions) on the rest of the motor, you should be able to make the same 230+ fwhp and 320+ fw ftlbs, which puts you close to a stock L98 engine. You could add another 10-30 hp and ftlbs if you ported the heads... but this is probably beyond what you have in mind for now.

So even with the above, you should be able to run squarely in the mid 14s.

There is much more you can do, but you said you are new to this, so you shouldn't make this too complex and neither am I. HTH.

 

i dunno about your cam choice, on a 350 i would tend to go a little bigger, but yes that 203/210 will be computer friendly, i think with a vafpr i think he could go a little bigger. but if you aren't upping the heads flow, and using the stock intake, going very much larger would start to hurt you.

too bad you don't have a roller block i am trying to sell my cam right now

if anyone is interested it is a UltraDyne Racing cam, 272/282 206/216 .447 .447

 

Haven't had the chace to run it yet at the track, but I have raced some of the same cars that I race at the track on the street, and the ones I couldn't beat befor I was infront of them by about a half of a car. But there again, both of us had trac problems, and I was on my worn out street tires, so I don't know, hopping to go to the track with in the next month, Maybe after I get my heads and intake, and after all of the mods I have done if I don't get 13's TBI commin off and a holly 750DP goin on.


The differance between the 2 cams are the lobe seperation, The one for the carb is probably cut at 110, when the one I have in my car is cut at 117, Hince forth no choppy idle.
