im curious if my 350 shortblock is good to 11 second ets in the quarter? any body else have a 350 and running 11's? my current trans and rear end may not be 11 second material, but is a t56 and 9" with 4.11's good for ets like that? what tires are good? i was thinking of getting slicks for my iroc wheels, anyone running this? suspension wise i was thinking of 50/50 rear shocks and 70/30 or 90/10 front sturts, with a drag front spring, i have a 1" rear sway bar to stiffen it up, want to try lca relocation brakets or lakewood traction action bars...

what are the specs on the cam? probably not with that edelbrock carb...

yeah the carb wouldnt make it i dont think. i think u would want atleast a 750

Edel Carb

Get a holley double pumper

650 dp or 750 dp?
cam specs

cam not important i can chenge that when ever, must be matched to my set up any way, this cam is smallish for getting in to the 11's from what i have seen on others car...

750dp all the way.

what gears?
would i choose different for a t5 to at56? i dont think so
i see every one in the 11's with 4.10's...

it all depends on power output and tire size.

3.73's would be fine with a 26" tire, but i went with a 4.10 gear and 28" tires to get more meat on the ground...

what 28" tire are you using? what wheel size? what did you do to get it to fit, if anything?

currently, i'm running a 275/60/15 M/T ET Street Radial. i love them to death! they are currently riding on some stock z28 15x7's so all i had to do was a small amount of massaging on the inner fender well on the bottom towards the lca.

i think an auto would actually benefit you in this situation though...a th350 would do very well.

i have thought about that many times, but the 5 and 6 speed trannys are for me, i like to street race, pick your stall speed, pick your gear, very flexable... my tranny wont every have to match my set up, only my foot. how much is it usually worth to go from a manual to auto? im sure its far more consistent, but that doesn't bother me too much.

how much does your car weigh?

.

last wieghed 3350lbs
since then i have swaped the motor and remove a few nick nacks, i think my current wieght is close to that, but lower...

also i was wondering if i should change my cam type? to say a solid or a hyd roller. how big a difference do this really make? can i make my gaol with a hyd flat tappet?

I do not think a hyd. flat tappet can get you into the 11's.

I am aiming for 11's with my 383 I am going to build with AFR 195 CNC ported heads. But my setup is completely different.

If you do, the only way is to rev the living hell out of it with a large cam, a single plane and a 750cfm carb.

And if you still dont......there is still nitrous.

In 99 or so my camaro 3350 w/me with 350, 9.5 compression,dart 200cc heads with 3200 stall run 11.8s best @ 113 with a solid flat tappet 242-248 545/560 lift lunati.
car was very drivable with a very intimidating idle.

HUGE difference in setups.

Whats your point?
You are telling him what he needs to get to be in 11's - I'm telling what I had to get in 11's that was pretty mild. - lets see!
He has better heads and slightly more cubes I had a bigger cam with not that big of converter...
And did not have to spin it that hard, used to shift at 6300/6400.

He has a gear banger, he should have a little more MPH - If effecient driving it could deffinetly see 11s

And what makes you think a hyd flat could not get him there?
With newer lobe profiles you can easily see 6500+ with right springs. Anderson ford cams are seeing 7000+ with heavier hyd rollers with steeper ramps on stock lifters.

Are you saying the Kenny Duttweiler TrickFlows are better than Dart 200cc's? I personally think not.

I also dont think the extra 5ci from an overbore is going to make a drastic difference.

And you seem to think I said you cant get 11's in a 350 or something. He asked if his current engine had it in it, I said no. The cam is too small, the heads arent good enough IMO, the carb is way too small...etc etc etc.

Are you serous?
The TFs smoke the darts - better 195cc vs 200cc for the smaller cubes keeping better port velocity and flow much better.
Darts are hardly breaking 240/175 73% I/E ratio vs 254/189
75% E/I ratio of the TFs and lighter aluminum.
Yes, they are much better... and easily good enough for 11s

112 mph can get you into 11s, so if you get that or better, the rest is up to you.


I said that the 5 cubes was slight, but on an engine making more that 1 HP per cube - thats 6+ HP, ill take it.

and for clearity, I did not think you said it can not be done - You threw an uncalled for comment about my post.
I was just calling a spade a spade.
I'm just trying to give the guy a referance.

How is pointing out your heads and larger cam making a "uncalled for" post?

OK,
My larger Cam - His better heads.

I'm sorry.
Lets continue with topic.

What do you have for pistons in your shortblock? You definately won't get in the 11s with 20cc dishes and a bunch of deck height. You'd need a very well tuned combo to get a full weight car in the 11s with that cam IMO. Good luck.

hey guys, i just checked back after a week...
about my current set up, the short block is the only thing i dont want to change for a while, cam ill go bigger, heads if they cant keep up they get ported, intake may change to a victor jr, carb was changed today(750dp), sop difference, now for tuning...

87_TA thanks for sharing the set up,

i have tryed looking around for 350's in the 11's and traxion's iroc is the coolest one i have seen so far

about the heads, i know my set up is way different, but on a 427 motown with 11to1 compression, and the edlebrock rpm roller cam the kd heads made over 500 hp, i really dont think ill max out the heads

flat topp 4 valve relief stock deck, my first motor to build. i did use arp fasteners

I have used my factory T/A shortblock in my Camaro with the heads and blower on to run mid 10's with.. and shifting at 7000 Only change was Hyperutectic pistons. That is still lasting, but I don't drive much
as engine is currently out - was going to put in another car but .....

Also when my original blower engine blew, I used a bone stock 80,000 mile short block from a early 80s pick up with my heads,cam,intake blah, blah and that run 12.0 and 10.9 on a 125 shot. for the last (3) races of the year. May have run 11's also but only tried (2) N/A passes, rest spraying.
That was my back up block - still running-just in my garage though.

So, Yes I have some confidence in the stock gear - but its a lot easier feeling having a good/better set of rods and pistons.

Both stock rear and T56 can run 11,s and many are - But if you want to leave hard IR: dumping clutch with slicks, 10 bolt will hate you.. They do not like shock - My trans am in sig still uses stock 10 bolt. But its an auto.

A 9" is very strong and will handle - But I personally would go 12 bolt or 8.8 due to weight. The 9" in my camaro probably added close to 100 lbs - but it has the stock pick up drums on vs the original alum. Reguardless, they are a good amount heavier - and use more HP due to pinion design.

The t56 will be fine, I can give a link of my brother in laws LS1 dumping clutch @ 7000 on 26x10's. His been lasting a good while like that.


I used to run ET street 26x10's on my stock GTA wheels, run best of 11.0 like that - I would recomend the 26x11's though, the trad width is still only 9.3 as opposed to 8.6 of the 26x10s.
They work well without tubes also due to shorter side wall

Sounds like a good plan, I would just try some air bags first instead of relocation brackets..
If you plan to dump clutch, I would go with a better TQ arm - preferably not trans mounted. Hope this helps.


Edit: Your Trick Flows with 254 cfm on intake can support 500+
So you have plenty enough head - well can you ever really have enough?
Victor and 750 dp was good move.

no victor yet, but i am considering it especially if i go bigger on the cam.

i think id have to step up to the LUN-60104LK or the LUN-60105LK to warrent the victor jr

also if i ran 26x10's or 26x11's would i got better with 3.73's or 4.11, b/c of the tire being short and all?

Assuming you will be shifting atleast 6300-6600 range, I would use 4.10s with the shorter 26" tire.

If you decide on a t56 out of a Trans/Cam I would go 4.30s with the smaller tire still. Due to the 2.67 first and having 6 gears you will not care one bit on the HWY.
The T5 would even like the 4.30s being that its first is only 2.75, but you may not like that on the hwy. But thats still only 2500 RPM at 61 MPH...Not to bad.

Or if you change tires, run a 275/60 28" on the street with the 4.30 on both trans. thats 2500 at 65 MPH w/4.30s. T5
and about 2100 or better w/t56

The first gear is the killer on GM trannies our t5 2.75 1st, mustang
T5 has I think 3.31 first. So they will help alot with that disadvantage.

If you were to go to 4.30s, that would allow 121 mph trap speed at 6500 - enough mph for 11.20s
Assume you are trapping about 116 thats only 6350 through traps putting you just at or a little past your probable peak HP.

I am not one to ever gear as I run 3.73s with a 28" tall, but thats on my Auto car - it seems to like the taller tire allowing more converter stall off the line.
Your 60 ft is going to be key in getting you your 11.s - the 4.30s will help you alot as a driver.

went the time in sig. I know, not the same, but just for reference.

do u think i could get into the 11's with a new stock 350 bottom end with ported heads and a nice cam with 28x10.5 slicks with 3.73 gears and a built 700r4?

- will 28x10.5 slicks fit on 15 iroc wheels fit without modification?

it all depends on how light the car is and if you know how to build a motor

Got a 355 in our roadster that runs 7.30's

maniak86

yes, this guy did

11's are fine, but traxion didn't have stock ported heads.

I got this off the Trick Flow websight:

Kenny Duttweiler Signature Series 23 Degree Aluminum Cylinder Heads
for Small Block Chevrolet
Dyno tested on a 383 cubic inch engine, Trick Flow’s 64cc Kenny Duttweiler Signature Series 23 Degree aluminum cylinder heads made 460 horsepower and 451 ft.-lbs. of torque—40 more horsepower and 11 ft.-lbs. more torque than thesame engine with GM L98 Corvette heads. The Kenny Duttweiler 23 Degree heads also made more power than Dart's Iron Eagle and World Product's Sportsman II cast iron heads.
The Kenny Duttweiler 23 Degree heads are a direct fit, high performance replacement for most original equipment factory heads, and accept most factory accessories. They feature a choice of 62cc or 64cc and 72cc CNC-profiled combustion chambers, 2.02"/1.60" stainless steel valves, hardened exhaust valve seats for unleaded gas, and 195cc intake ports with a high velocity, small cross-section design to promote low rpm torque without sacrificing higher rpm horsepower.

The Kenny Duttweiler heads are available with three spring sizes: 1.25" single for cams up to .480" lift, 1.47" single for cams up to .540" lift, and 1.46" dual for cams up to .600" lift. They come fully assembled with valves, valve springs, locks, retainers, rocker arm studs, and guideplates. The heads are 50 state emissions legal under CARB E.O. number D-369-4.


Whats the big deal about these heads? They are only cnc'd in the combustion chambers and the ports are as cast. There are cylinder heads out there that are better for a few dollars more
for complete CNC porting and still smog legal.

You can run 10's with a solid lifter cam. Racers have been doing it for decades. You don't need a roller cam to go fast (It helps but not totally necessary) .

"The Kenny Duttweiler heads are available with three spring sizes: 1.25" single for cams up to .480" lift"

news to me, looks like i need new springs...
paper work i got says good to .520" lift and i bought my cam by that, oops, new cam and springs time @ least new springs...

i keep trying to make a shorter list, hard to do i want all the best & baddest stuff on this car
-4.10 gear, 4th gen posi, 28 spline axles, rebuild stock rear end accordingly, like to add T/A cover too
-275 60 15 M\T radial, 255 50 16 drag radial, 26X11 M\T
-reloacate brakets, new torque arm(not mounted to trans as per 87_TA)

I went 11.6's naturally aspirated on the stock shortblock. Your standard big cam, AFR190 (ported), miniram setup. She would have gone 11.4's with a good, fast, hard shifting tranny and a higher stall converter. I only went down the track 2 times with that setup and the tranny was the stock tranny that GM put in the car in 1990 along with a shift kit. There was definitely more there.

Would have been nice to put it in the lower 11's naturally aspirated. She had it in her. But, I was pretty much done with the project.

t

ive run 12.4 with a stock shortblock, sportsman II heads, and a small cam. 455/455. Dual plane intake and a demon carb. and a t5. 9 inch rear though with a 28/9 et drag. 4/11 gears. i know its not elevens, but its close.
