Heres the setup -

350 .040 over thus giving a 357
AFR 195cc heads 68cc combustion giving 9.5 ratio 2.02 int flowing 260cfm at .500 1.6 exh flowing 190cfm at .500 lift and my springs are limited to .550lift
Hooker 2055 Headers along with 3" exhaust
TPI setup stock at moment however will adjust this to match afr 195cc head flow numbers or as close as possible.
Vortec V1 Supercharger will be running low psi around 6-8

Now my question is what would be the right cam for this setup to get the most potential power from the motor saying my rpm will max at 6000.

And will I have to run 92+ oct gas or can I run 87 ?

 

I would recommend the following:
I:220, E:230, LSA 114 degrees. Speed-Pro has a nice one with these specs and its only about $175.00. I assume that this is for a street car. I'm sure you'll get 100 more opinions on this but these numbers will give you lots of performance. If you keep the boost to around 6PSI, you won't have any problems with octane, head gaaskets, etc. 9.5:1 is not bad but 6PSI is about all you should push. That'll give you a good 525 hp (or about) at the crank. Do you already have the heads? They (AFR) make 74cc too. If you drop your compression to around 8.5:1, you could run 8-10 PSI and make about 600hp. That's my 2 cents.

 

yea, you'll need 92 octane. No chance of running a blower with 87 octane.

you want a roller cam or flat tappet?

 

You'll need bigger injectors too. I'd say 50-60 pph. I would also recommend that you use Peak and Hold (low impedance) injectors. This requires a driver but they're available. Again, you're going to hear 100 more opinions on that too but here's the thing. When you double the injector size, you cut the pulsewidth/hp in half. Example: Let's ay your cruise characteristics are the following : RPM 1800, Speed 65MPH, MPG 24.0, the injector pulsewidth is 0.8ms with 22pph injectors. With 55pph injectors the pulsewidth is 0.32ms! That's for a double-fire TPI computer (1227165, 1227730). Those are pretty narrow pulses!! The low impedance injectors are much faster, can respond to narrower pulses, are easier to tune and will give you lots of hp AND great cruise performance. Gas ain't cheap. That makes 4 cents from me.

 

they have 60 pound motron injectors that you can run with the stock ecm.

 

Sure they do but you won't get good idle and cruise performance unless you use peak and hold. Surely, we will soon here from someone who CLAIMS they're running 65 pph saturated injectors in a 5.7 and getting 25 MPG. Don't you believe it!

 

Well, to start with you’ll never match the TPI setup to something that will want to run 6000rpm or so, so the proper cam for this combination will not work with the intake or vice versa, and the fact is fighting what the individual parts want to do is just a sure way of getting a combination that will not make nearly the power that it should.

As far as cam for a supercharger that will get into about that range I’d be looking at the CC lobes and something in the 224/236/114 range, something more like 218/230/114 or maybe even 212/224/114 would be more appriate for the rest of your combination, but you’ll be looking at something that will most likely top out in the mid/high 5xxx range with those.

Really, on the smaller ones I’d probably seriously consider a 112 LSA, but it will be more difficult to tune correctly and be much more dependant on getting things tweaked just so.

With 9.5:1 and boost… are you kidding? Yea, you’ll need good gas.

The bigger the cam the less octane sensitive it will be, but still, with that compression and boost you’re pretty much stuck. A point less compression and things change dramatically, my brother’s car runs about 8.6:1, 10psi boost and runs about the same on 87 as it does on premium, but only gets raced on 92+ anyway just for safety.

It depends on what you know and how good you are at tuning. With a purpose built setup I could see how you could build a boosted v8 powered 3rd gen that could get something in the high 2x range with large saturated injectors. FWIW, my brother’s supercharged 306 powered ford LTD running some 77lb/hr saturated injectors averaged between 22 and 24mpg on it’s last 2 road trips (last one from DC to Englishtown for MM&FF luxobarge shootout), and the combination of low compression, biggish cam, large bore… all add up to something far from optimum for mpg numbers.
