i have a 95 camaro, 383 lt1. im looking to buy a set of trickflow heads and i would like to buy an aftermarket fi intake as well. i have looked at porting my stock one but for the cos would it be better to buy aftermarket. i have seen some sheet metal ones but those are like 1500. i want to buy aftermarket but does anyone have some advice on a good aftermarket intake.

Chances are very good you have no need for something that elaborate unless you're shooting for north of 500+whp and have the valvetrain to support it. Any aftermarket pieces all require some kind of extensive modification that extends beyond the initial cost of the manifold so you have to keep that in mind.

I'm pushing 450whp with my 383 using the stock ported intake manifold and seem to be doing just fine. Your money is better off spent elsewhere, like having those Trick Flows ported (i.e., not using them as-cast).

its a competition 383 fully forged bottom end. i have stock heads, stock intake, comp cams xfi 292, hardened push rods, 58mm bbk, trick flow 44lbs injectors, 175 nitrous works wet kit, 1.6 roller rockers, 1 7/8 long tubes. trans is 6 speed with ram hd powergrip clutch, mcleod bell housing, aluminum driveshaft. moser 9", 33 spline, spool, 457 pro gear. asco drag struts, bmr trans crossmember with torque arm mount, bmr torque arm, lakewood lower control arms, competition engineering frame ties, 6 point cage, bmr pan hard bar adjustable, strut tower brace, ect. im forgetting tons more but i think you get the point. im at the next point of replacing heads and intake, this is why im asking.

What do you want out of the car, HP/ET wise?

Gitsum95z

Thats not the question. Hp/et is not my concern right now. I understand why you are asking this question but I will adjust as needed if performance isnt there. My question is what aftermarket intake would work best with a set of trickflow heads. The reason im changing from the stock set up is I have a cracked head. My goal right now is to find a good working combination of heads and intake. If the car ran 10's,9's ,8's it would be fine.

RamAir95TA

Nevermind.

Gitsum95z

I totally understand why your asking and dont think your asking the wrong thing. I just feel that a whole other conversation at this point. I already purchased the trickflow heads. now im looking for the closest matching intake.

Ramair95ta I do appreciate your input please dont mistake that

You will not find a bolt-on ready aftermarket intake to fit LT1 heads simply because the stock manifold works extremely well and the performance aftermarket world knows this. All of these sheet metal intakes, single planes, Vic Jrs, etc., are all expensive and take some sort of modification to get them to fit.

"Closest matching" is not an applicable term here. You pick an intake manifold based on your desired RPM range, cam specs, etc., not what "fits." Without your goals and expectations it is not possible to provide you with the correct information to determine whether or not your goals are outside of the capability of the stock manifold.

Short version: If you're going to be spinning well past 7k with a big HR/SR with an aftermarket PCM like FAST, Megasquirt, etc., then I recommend a converted Vic Jr or Supervic. If you are going to be running ANYTHING LESS THAN THAT, a ported stock manifold is plenty. Take my word for it.

Gitsum95z

I agree with all of that. The only reason I mentioned I wasnt concerned with,the hp part is of all of the fi aftermarket intakes I have found all fall into the same rpm range. So picking from those which ever was the best match...
I appreciate ypur input. Now you have my wheels turning on the carb side... Any input on that at all. Im just trying to get the consistant. I run delay box bracket and just want a strong running car with a consistant performance. That is why it doesnt matter what et, or hp. I hope that helps thanks agian

Any sort of "aftermarket" intake for an LT1 is going to require some machining and welding to make it work. You'll need to seal up any water ports on the intake, redrill the bolt holes, install injectors and make fuel rails if you retain EFI. You're looking at buying the intake and probably spending another $800 bucks or more to make it work. It's not a simple bolt on swap.

People have made 3 times the power you're seeing with the stock LT1/4 intake manifolds. Why fix what works?

I would have the heads proted and have the stock intake ported. http://advancedinduction.com/ give these guys a call and have the aftermarket heads and stock intake worked over; I would also have them hook you up with a cam.

thanks guys. i have heard alot of good things from ia, and seen some nice videos too
im actually going with a swap instead. thanks for the input
