whats next?? Ok so I started getting more and more into building my 95 z28 and drag racing the past 2 years. my car has went through a complete transformation. Started off as a heads cam t56 car. First came the 9" rear with 4.11 gears after i grenaded the 10 bolt. Then wanted more so last winter i bought a 396 stroker already built for my car. Engine specs are: -4340 forged eagle crank
-forged scat 6 inch rods with full floating wrist pins and arp bolts-Mahle forged pistons-splayed 4 bolt mains-cometic mls headgaskets-12.0:1 compression -fully ported Trickflow heads by Lloyd Elliot with scorpion 1.6 rocker arms, ferrea 2.08/1.60 stainless valves with 5 angle valve job, comp cams locks and retainers, manley pushrods, .650 lift dual valve springs-LT4 intake fully ported by Lloyd Elliot-arizona speed and marine monoblade tb-comp cam hydraulic roller.585/.580 242/248 110 lsa-canton 6 quart oil pan-delphi Lucas 42lb injectors-csr electric water pump with polished GM housing-24x conversion with LS3 coils-tuff stuff chrome alternator-mean machine billet alternator relocation bracket-custom power steering reservoir with billet power steering pulley-MSD plug wires-polished fuel rails-ARP head studs along with ARP bolts throughout entire motor and accessories-SFI approved crank pulley and flywheel-melling high volume oil pump-felpro gaskets throughout motor. Then after by summer time i wanted to go to an automatic so i ordered a transbrake th350 rmvb and 8" 4400 stall from coan engineering. Love it! ive since been to the track a couple more times and have had a best pass of 11.19 at 121. Mostly 11.20-11.27. Its pretty consistent given ive had wheel hop and traction problems. So lca relocation brackets and bmr extreme anti roll bar are ordered. Finally, my question to everyone is.... whats next to do? I still wanna go faster. Should i be looking at a bigger cam? Is it solid roller time? Or nitrous?

Yea ive got a nitrous outlet kit that was on my old motor. just wanted to get all i could n/a first. Im hoping for a 10.8-10.9 on motor with a good 60' .

The relocating brackets will help 60'....and if you are not, you should be running a "Tire".
improve 60' and that gain about doubles at the big end
Once you get the 60' as low as you can NA...then add the juice as soon as you feel the Tires will hold it

I vote perfecting what you have first and then adding the juice. Good call on the suspension bits that you just bought. I could see your setup running a ~ half second quicker and a few mph faster once it's completely sorted and dialed in. Then toss on the juice and shoot for 9's! Just gotta make sure the car and you have all the needed safety equipment to pass tech unless you already have that taken care of.

Best 60' so far was a 1.58. Havent weighed the car yet but its full interior. Abs delete, ac/heater delete. Planning on doing a few wieght reductions this winter.. i do have strange sa front shocks and comp engineering rear shocks, sfc, short torque arm lca, panhard bar.... have 2 step setup at 3800 with my transbrake. Once i get the suspension parts on, and the weight reduction( 80lbs) id like to be in the mid 1.4 60'. Sound possible?

The times you are running are pretty spot on for the mph. Is the car dead hooking or is it spinning at all? If it is dead hooking, you might not be able to do much in the 60ft area without a converter or gearing change. The 80lb reduction should be worth close to .1 in the quarter. 10.9's should be doable with a 80 lb weight reduction and some tuning, etc.

the car hooks but as stated has wheel hop problems. And lifts the driver side tire but not the passenger. Figured the lca relocation brackets and bmr extreme anti roll bar would help my 60'. Or you think im pretty close to what its gonna be? Also, have my strange sa fronts at 2. Have read alot of people run them on 0-1 and get better times than on 2-3. Anyone have any experience with them? Oh, and had 275/50/15 mt et streets but am stepping up to 28s for next year. Will that help or hurt? I shift at 6500 but cross the line at around 6800. idk if 28s will help or do i need a gear change?

You might gain a little in your 60 ft without the wheel hop. You are pretty close to what the 60ft is going to be unless your tune is off down low.
I set my suspension up very tight at the track. I run 4 on the fronts and 8 on the back (These are Hal/QA1 12 way shocks with 1 being loose and 12 being tight). Not sure what the strange shock adjustments are but you will want the tightest setting that still gets you the best 60ft if that makes sense.
The 28's will most likely slow you down from where you are now as they will lower your torque multiplication (like going from a 4.11 to a 3.90 gear). However, when you spray you will need the 28's to get more mph from your current setup so it should be great on the bottle. The 28's will drop your rpms down going through the traps N/A.

Ok thanks for the help guys! im gonna put the suspension parts on, doing the weight reduction and try the 0-1 settings on the shocks and focus on fine tuning/perfecting the setup i have this coming season and hope for another personal bests! lets hope a 10.9 is in it!

@nostang. Would that cam work well with just a le ported lt4 intake? I see most guys go single plane.. Would it still make decent power with the lt4 intake or would it be a waste?

I don't see why it would not work with a ported lt4 intake. It might make more power with a single plane but the ltx intakes flow pretty well when ported. I know the cam will want to shift at 7k+ rpms. What size intake runner do you have on your trickflows? What does Lloyd Elliot say about the cam and your setup?
