Default what next? max effort 346

here is where ill start. I have a stock cube ls1 346 that i want to go max effort with. specs so far are

ls6 intake
stock heads
trex cam
stock rockers with comp cam trunions
only acc. are stock water pump and alt.
underdrive pulley
1 3/4 hooker super comps
4k stall
430 geared 12 bolt
built 4l60e

the car made 415/ 390 and now im looking where to go next. I was thinking going to a fast intake, but which one? is the 102 too much or should i just find a 90/ 90 setup? I also want to go to some 1 7/8 headers and an elec water pump. Maybe some prc 215 heads or nitrous? Sorry for the long thread just want some opinions and ideas on where to go with this thing next. Thanks in advance guys.

A better pair of heads to take advantage of the air coming in and going out and better use that cam.

Better heads, better headers, port-matched 102mm intake/tb, EWP. I'm assuming you don't want to get into a complete tear-down for blueprinting, etc? Probably add 42lb/hr injectors and a Walbro fuel pump, too.

That's not a bad off-the-shelf cam, but you might be able to get more power with something custom-spec'd for the specific heads you'll be using and the power and powerband goals for the car.

ahh forgot to mention fuel system is already taken care of also. I know my head choices are limited with the trex without fly cutting. Im still skeptical of going on the bottle, but she might need it... got a 413ci first gen small block on a buck fifty to try and conquer

fast 102 intake and tb are for sure now, 1 7/8 headers and elec water pump hopefully some heads also

EDIT: this is going to be costly! but hey you know what they say... gotta pay to play LOL

When you say max effort do you mean dyno number or track times?

Ai 226 CC 243 heads milled depending on cam choice
Call EPS and talk to Geoff about a cam with the above heads and ask him how much can be milled. You will want to stick with stock sized valves
Mamo ported Fast 102 with 102 TB
1 7/8 Texas Speed headers with duals
Gm injectors from a Supercharged Gran Prix,Regal..
Big Fast Toys air lid and Chris Ram Air
Convert to speed density. and have a good tuner keep the car for a week or so.

You should have a 10 second car that can be driven anywhere with a 28 tall tire.

how is that? max effort is trying to get everything you can out of the car and making it work well. Im trying to do what i can with the little baby 346. I want to push all i can out of it and be reliable which is also why im not wanting to go on the bottle. I know it will take more money to go fast and be n/a, but i feel the motor will last a lot longer and stay reliable like i want

max effort to you is building up that 346, max effort for someone else is dropping in a built twin turbo 454.. So max effort is relative to the builder is all he meant.

When the title specifically says "max effort 346", it should be clear to everyone that he's not trying to do a twin turbo 454.

this is what im thinking also as of late. I found out also i have a cracked primary on my drivers side header after changing the head gaskets so 1 7/8ths headers are a must now. thinking the TSP's, they look like a great header for the money and are stainless now! fast 102/102 and headers then heads once i find the right set for the right price

If you've already got an LS6, unless you can get a great deal on the 102/102 I'd put that money towards heads and the port work. The 102/102 set-up ramps up in cost when considering new fuel rails, piping between the TB and MAF, if not a larger MAF and lid as well. Most of which will cost you the same as a used set of heads and a good port job or an aftermarket set.

You'll also see better gains doing the heads first. The stock heads max out pretty quick and all that air from the 102 is being wasted.
