Which kit?

I'm looking at plate systems for my Camaro. 4150 Holley.
Car is back halved, ladder bar, 427 BBC, manual 400 w/brake, blah, blah, blah.
I'm looking at plate systems to spray up to 250 h.p.

The choices so far are:
a)NOS Cheater sytem for $475.95
b)Edelbrock Performer RPM for $439.95

These systems appear to be virtually identical. Does anyone know if there is
a difference between these kits? Any other recommendations to get to this
level of performance?
 
get the RPM kit, at the very least its nicer because if comes w/ Braided flex lines that run from the solenoid to the plate instead of the prebent hard lines that NOS includes
 
That would be the one. I can get that one for $465. shipped.
If it can really make 300 h.p. that's a great deal. The NOS and Edelbrock
kits can "only" do 200 for the same money. Whichever way I go, it should get
the pig scootin'.
 
I just bolted a Zex perimiter plate on the IROC. The plate looks great and should work fine but their jetting looks wierd. Their 300 shot says to use a .125 jet! Sounds giant to me. I'll be starting with the 150 tune and up from there. I've searched for feedback with one result from a dude overseas who's spraying 200 on a 454 and he says the plugs are all even and the tune is solid. If that means anything to you.:)

A Big Shot plate is used by most it seems and everyong has their own take/tune on it. Yellowbullet.com has tons of threads and info.
 
I've been reading Y.B. too. I think the perimeter plate has small enough
orifices that it is supposed to act like a fogger to some degree. I'm leaning
towards this one. Mines a high compression 427. We'll ease into it.
 
go with the big shot plate kit, people have been using it for years and it works great...i picked up 4 tenths spraying the same shit from a cheater to a big shot plate kit....

Holy shit really? That's a chitload of difference. I will give this further thought.
Thanks for all input, keep it coming.

I put one on my car and was NEVER sorry. I have it set at 175 and can step it up to 400 when ever I build a motor that can handle it :icon_mrgr The best thing is its a kit that I can grow into and not grow out of
 
O.K., this is getting serious now!
Thanks for all input so far.
I guess I'd like some advice from you guys who've been there on what my engine can realistically use and survive at least one season with.
I think the Power Shot is the best value to grow with in the future.

The spec's:
433 BBC, 13.5-1 comp Arias, Lunati steel rods, Chevy steel crank, closed
chamber -840 iron rect port heads with 2.25 int and 1.94 exh stainless manley valves, Crane solid flat tappet 262/272 @ .050, 108 LSA, .630/.630 lift. Ported and epoxied Holley Strip Dominator and 4150 830 CFM carb.
The trans is a manual 400 turbo w/brake. Convertor is 9.5" 4500 flash stall.
9 inch rear w/4.56 spool. Tires are M/T ET Street 32 x 16.
Ladder bar / coil over suspension. Back halved car essentially.

I guess the issue at hand is what is a realistic dose. I'm concerned that
the pistons and cam are not really the best candidates for a heavy dose?
So I would just ease in with a 100 shot first, watch the plugs and keep
rejetting and pulling timing per someone's tune chart in 50 or 100 h.p.
increases until what? When will I know I'm at the liveable limits without
breaking a ring or something?
Thanks again for your input.

you can jet down the big shot plate as much as you want too..it will always be safer because it has more holes in the plate...you just need to pay attention to the plugs and be realistic with the tune...if your gonna hit it with 500 you should expect problems...i sprayed my old shit with 175-225 for 3 years and never hurt anything on the motor...
 
225-250 would be the limit on a stock crank to be safe I would have no problem hitting that motor with 175 or 200 all day long

1) .018-.020" comp / .025" oil
2) Aeromotive #11203 pump, #13301 bypass regulator, #10 supply,
#8 return.
3) #6223 Chevy forged crank
4) MSD 6AL / MSD pro-billet dist / 2 step
Will add some kind of ign. controller to pull timing out.
