How to increase low end torque without FI?
Hi guys
Without using any FI method (S/C, TT, N2O, etc), what would be the best way to increase low end torque on my C6/Z51 MZ6? I don't care much about top hp/torque and track numbers. Just want some more maggie-like power at 1500 - 3500 rpm.
Any thoughts?

headers, exhaust, intake, and tuning. Stressing the tuning. Find a good tuner first that many give good recommendations. Than get their recommendations the intake and exhaust parts they like. Something like an LG header.
Really want some exciting low end power. 4.10 gears. You'll be shifting a lot, but it's a hoot.

more torque? that's got to be a 402
use a cam for that purpose. all of the strokers i've seen tested start with at least 35-40ft-lbs more torque at the bottom of the graph..
can't beat that w/o a power adder.
cheaper would be 4.10's with some lg headers..
a lot of people claim their xyz cam helped torque but, in all of the cars i've built/driven, none have made a small block a torque monster..
as for your comparisions, the h/c car will kill the other one from just about everywhere but, it will have "lightswitch" style power. by that i mean power will start at a higher rpm and pull further up the tach
to each his own. personally, i don't care for cars with cams. weird idle issues,ect.. i'd rather use 1.8 rockers and give up some top end hp
and use a set of afr 205's to help out the mid range.

Yep, 4.10 gears will be the biggest thing you can do to increase low end response (for a reasonable price). Another thing to do, is get the car tuned and have them bump up your timing about 3 degrees in the low end. Make sure you're running 94 octane fuel though.

4.10's will make the biggest difference...but you will be shifting ALOT. Try and drive someone's car before deciding on the gears....I have driven one...it made a big difference in the bottom end. As far as "maggie-like" low end...it's not going to happen without the maggie. My car makes 100+ ft lbs over stock at 2500 rpm's..your not going to make numbers like that without going to a bigger engine or FI.

I made up my mind to go with Maggie tens of times, because I want that low end torque. But whenever i see Mustangs and Camaros with high-rise hood, I couldn't pull the trigger. It's just not my style.
But I still don't know. I'm gonna decide before spring comes, I just can't decide which way to go - Z06, TT, Maggie, centri, H/C, 403/427... I just don't know because i have never driven one with any of them.

Nothing on the stock displacement, including the Maggie, will give you more torque at 1500. Maggie only gets on the boost (and hence torque)at 2300 , which is obvious from dyno graphs. Out-of-the hole torque either comes from adding stroker cubes or better gearing (4.10s). My car has the 4.10s and it is a rocket off the line. I have badly wasted a BPU Subie WRX (the300HP version) with my gears. Guy was shocked.
However, to make the gears work, you need Bilsteins to stop wheelhop and Nitto R2 / NT01 tires to put the power down off the line. I use 305 rears on custom-widened Y2K 18x9.5 rears (now 11 inch), which were done by James at Weldcraft wheels. This is the ultimate stealth cheatr setup.
Well, OK, there is NOS.

I have had 3 different blower engines, one of them a 4.3L V6 in an S-10. With no other mods, I had way more TQ at 1500 RPMs than most h/c V8s.

If you're interested in the maggie, but are worried about the hood, take a good look at the RK Sport Hood. Everyone that has seen mine either likes it, or doesn't know it's been changed.

That is the Ideal way with a reverse split cam. However, with out opeing up the engine.
Best is to have a good tuner do his magic. A good tuner can tune the car( with current set up ) for a more flat torque curve then the stock tuning curve.
Bolt on are sexy, but a tune for $400 will get you closer to what you want then $2500+ in bolt ons

I would cam the car and add a comp cams adjustable timing chain and advance it enough to get to 8.7DCR for the best low end response coupled with 4.10's and headers. I've seen 400rwtq at 2200rpm.
Air cleaners and $1000-mufflers are a waste of money.

You wont notice a difference between 4.10's and 3.90's. The only reason to use 3.90's is if you track the car and run out of rpm's up top (10.6 or faster)

, and his setup is well tuned.
