I had the same problem with my new throttle body. It feels like cruise control but if you blip the throttle real qiuck it acts normal until you touch the gas again. I made sure that there wasnt anyting binding and lube everything up. The problem was still there so I bought a spring(for a carb I think) and connected the throttle arm to the bracket the cable feeds through. Now the spring pulls the valves shut and returns to the fully closed position. The spring isnt too heavy but I like how the pedal feels real firm now. Its a cheap and easy fix and is probably worth a try.

 

I thought during break in period you don't want to go over 3500rpm or more than 1/2 or 3/4 throttle. I'm not sure either.

It doesnt matter, I'm gonna be somewhat easy on it for the most part. I rarely hit 5,000rpm unless its really worth it. Take confidence in the fact that when you get yours done, you will see what I mean when I say that I didn't take it over 3000rpm today and it was still crazy fast.

I love the 3.73's with the T56. I don't know how perfect it will be for the track (don't know if I'm gonna run outta gear or not) but it's gonna be a blast on the street. Definetly gonna need some suspension mods to put the power down.

Just dropped it off at home for the night. About to head back to Rutgers and come back down here tommorrow to drive it more, gas it up, wash it and fix the sticky throttle.

 

Oh i believe you! I drove my friends 98' C5 and it felt really fast compared to the 305, probally b/c it is! Anyway, he feels he will smoke me, i think otherwise. Either way, i should be happy with it. After driving the vette, i should be plenty happy with this set up for a while. Can't wait! Later

 

the car is home! sweet... if ur there.. i might stop by and see it... let me know... aight man peace

 

Bigal, bout to go home now.

IM me on GPA 0point0 or on JRShotliff.

 

How's it running? Put a lot of miles on it yet? Later

 

Any update on it?

 

Yes, I have updates.

I bought a universal carb return spring for the sticky throttle and hooked it up. The RPM's actually go down when you put the clutch in rather than up... and it goes all the way back down to idle. So nice to drive it now that it is functioning properly.

I changed the oil today after roughly 400 miles. There was a pretty large amount of metal shavings stuck (magnetically) to the drain plug, as expected with any new motor. Can't wait for the break in period to be completely over so I can go WOT all the way to 5500 and see what this thing can REALLY do.

While I was under the car changing the oil, I saw the Y pipe that was made for me for the first time. It came out great. Nice smooth bends, and a great 3'' Y transition into the 3'' cat! No more exhaust restriction for me! (My original dual cats were severly butchered and were holding me back several tenths in the quarter).

Got some new headlights... cool blue. I know nobody cares about headlights BUT you (Camaro owners) may have noticed that the halogen sealed beam replacements are kinda dull and actually just plain suck. The cool blue replacements (which are not blue by any means, so don't fear being r i c e y) are much brighter... quite an improvement. Camaro people, keep this in mind when it comes headlight replacement time because "replacement time is upgrade time."

I still need to do some minor cleaning under the hood: strut tower bar, clean the plenum, etc. One other thing that comes to mind is that my clutch pedal is squeaky. What can I do about this? I haven't had the chance to get in there and look at it yet, but is there something I can grease to get rid of that???

Thats about it for now on the updates for those who were interested.

 

I commend you for resisting the urge to hammer down.

 

There is a long bolt with several bushings that the clutch and brake pedals pivot on. I'll bet that a dab of grease or a quick spray of WD40 would help.

 

Edit: While cool blue headlights will enable you to actually see the road at night unlike halogen lights, you will be flashed by other drivers who think they are too bright!

I raced an L98 vette on the highway today. He said he had some little mods like exhaust, 1.6RR, etc. Only reason we pulled over is cause when I was blowing passed him at 120mph his car started smoking badly. Turns out it was tranny fluid from the newly rebuilt (by Lee Myles ) automatic, and it was messed up already. Real nice guy, bout 60 years old... was glad to pull over and talk with him and meet new people. He loved my car and was shocked to see the F-Body blow passed, especially at such high speeds! Score +1 for the thirdgen world! Enough for now...

 

Yeah, we will meet up soon! There are very minor things left to be done and the car should be running soon. I am hoping for next weekend but we will see if i run into anything else! I'll post it and try to get pictures up on here too. Later

 

driven the car anymore? how come you went with the zz4?

i've been thinking about the fastburn 385 myself...just don't know enough about it yet.

 

hey man, are u home for break yet? let me know, i gotta see this awsome car... let me know the deal and maybe we can meet up before xmas? aight man peace

 

definetly bigal....

Kandied91z... I would have gotten the ZZ430 if emissions wasnt a concern. Anyway, the ZZ4 is strong... real strong, so a fastburn 385 will be awesome!

 

wait.. u on line? if u are.. ill holla at ya!

 

Lube your throttle blades. Remove the boot in front of the throttle body and lube up the inner and outter parts of the two valves. I always have the sticky problem after I use TB cleaner (which I'm guessing also cleans out any lube). I used some tranny fluid last time (small amount) and it's worked perfect!

 

L98IROCZ89, you have a PM.

 

TTT for an update

 

You want updates? I'll give you updates...

It's snowing around here

My front left tires blew out the other night

On the bright side... I have noticed that I CAN NOT do WOT in 1st gear at all without suspension mods or possibly better tires. So I am going to attempt to turn a negative into a positive by moving my perfectly fine rear tires to the front, and buy some Firestone Firehawk SZ50s. Customer satisfaction, traction, cornering, etc is really really high. My question is, on stock rims and suspension should I order 245/50/16 or 255/50/16???

Anyway, probably about 1500 miles on the motor/trans/rear now. Bout to change the oil again, and then get it to the track ASAP.

 

L98IROCZ89,

I sent you a PM asking you some particulars on your combo........

I need some input.... when you get time......

 

Where you going to the track, Atco? I would love to go with you but my car is not running yet. I ordered a few more parts and the weather, as you know, has been crappy for the past two weeks, whenever i would have a chance to go out there and work on it. I'm telling you though, its so close to being done. Sounds like you can use synthetics now with this oil change. Not bad with the mileage! When i get my running i think i will just drive, for days. Something i wanted to ask you, hows gas with it? Roughly, how much does it cost you to fill it? Later

 

I have a 87 gta, 305 and im looking for a cam and i found this thread is it true that I can put a ZZ4 cam in to get mid range power. Also what are the specs of the ZZ4 cam, and what brand makes a cam that is identical to it. thanks for the help

 

congrats on the new motor, im building a new 350 from the ground up, most of the parts i plan on using are in my sig. and i hope i get great power out of it as you did. im just wondering if i should go wi9th the LT4 cam with a superram or go with a little milder cam because i have to pass chicago emissions and i dont plan on hooking up any A.I.R. thanks guys, good luck when you finish breakin it in, hope you show some people whats up. take care.

Russ

 

I read somewhere in a repair manual or something that the 350 TPI w/ cast iron heads that was in the F-car is actually a L89 (eightynine), not L98 (nintyeight) like everyone calls it. The L98 was the aluminium head motor in the vettes. I think this is a big confusion amongst the aftermarket.

 

Nice. ZZ4's are awesome engines. I certainly love mine.

I had a TPI manifold (Edelbrock Base and SLP runners) before the MiniRam and it was extremely torquey.

 

Hows the motor with the minram? I only ask b/c i am doing something very similar right now! Later

 

In a word, AWESOME.

The torque curve is extremely flat. I can tell that it has a little less torque at about 3500 rpm, but everywhere else it's much better- off the line and especially over 4500 rpm. The entire set up consists of the ZZ4, the MiniRam, with AFR 180cc heads, ZZ4 camshaft, and 1 5/8" full length headers.

 

Thats cool. Mine's similar in that i have the zz4 but i am using the fastburm heads with the miniram as well as the hot cam. Can't wait to get it started! Any track times on your set up yet?

 

Not yet. But from combinations I've seen, I think I'm right around the 400 hp mark. Though yours sounds like it's going to be in the 420 hp range!

 

Hey Pro Tour you got any numbers for that engine?? IE 1/4 mile maybe a dyno run?

 

Maybe in the future. For now, I really don't need exact numbers to tell me the thing is fast. The way it's set up now, just stomping on the gas from a dead stop it'll blaze the tires (275/40-17's) through first gear and almost all the way to the top of second.

One day, maybe I'll stick it on a chassis dyno and see what it makes. But suffice it to say it gets the job done.... at least it will again once I figure out this nasty misfire I'm battling!

Besides, a ZZ4 with better heads is nothing new. They typically make around 400 or so horsepower. Maybe a little more, maybe a little less.

 

Yea but its not about the ZZ4 power or the power that the new heads on the ZZ4 put out... its about what the ZZ4 puts out with EFI on top of it. The ZZ4 is rated at 355hp/405tq with a 650cfm carb, long tube headers, and open exhaust. My question is, what is my ZZ4 gonna put out with a modded TPI on it? Further, I am curious what yours will put out with the miniram on it.

I am going to put mine on a chasis dyno soon. Possibly this summer, I will complete the SuperRam and get the plenum/runners to match my SuperRam base which should be slightly better than the stock ported plenum and SLP runners.

The biggest difference I am hopeing to achieve by doing that is not a drastically higher peak HP or TQ, but a much flatter torque curve which should translate to a lower ET.

I have done a lot of searching and have not found any ZZ4 TPI dyno numbers. Someone needs to take one for the team and find out for sure. I am thinking that it chokes 10hp out of it and adds 5-10 ft-lbs to it... just a guess tho.

86IROCNJ, how's your ZZ430 coming along? I want to come meet up, but I need to take care of my blowout first

 

Im curious too on what kind of numbers they make with tpi,ill be taking mine to get dynoed ,hopefully in the end of february.

 

L98IROCZ89
I am getting ready to drop a ZZ4 with the SuperRam on it into my car so I have been following this post for some time.
Sounds like a good combo to use.

 

L98, should be ready soon if the weather holds up! Besides that going against me, everytime i go out there to work on it i find that i "need" something more to finish. Hopefully i bought the last part for it and it should be going soon. Probally before the 20th if i can get out there. I plan on breaking it in quick, like just driving for hours and doing oil changes. I'll contact you soon for a meet. Good luck with the blow out! Later

 

A MiniRam isn't going to make any more horsepower than a carb. It may make a little more low-midrange torque due to the port fuel injection's better atomization and distribution, but that's about it.

 

Z_Ghost - Given that this is up to 90 something posts, I'm gld to know that someone is definetly getting something out of it. I do think the ZZ4 w/ SuperRam is an awesome combo... it pulls like a cigarette fiend who hasnt smoked in a week and it will pass emissions if need be and still get you somewhat respectable gas mileage.

86IROCNJ - Hopefully you do have all of your parts.... I wanna see this beast! The ZZ4 is an incredible motor. My friend has a ZZ4 with the LT4 Hotcam in his vette and that is an incredible motor too! The point is, you have the full out ZZ430... I can't even imagine the power that thing puts down

My new tires should be here tommorrow, Monday the 13th, and I will probably go get another oil change with it. Can't wait, I have been without it for less than a week and I am on horsepower withdrawal. I have no idea how I made it from May-December without the car?!?!!?

 

L98 ,yes, my set up is similar to the zz430, but i'll just set it straight that it is not the actual zz430 from the factory. Not being a di ck, just setting it straight so that others do not think i am trying to pass it off as one. Also, were you at a Home Depot today by any chance? I know your having tire problems but there was a car just like yours there only it had chrome irocs, 17s to be exact. Looked good with the white, red decals, and chrome wheels. Just curious! Talk to you later.

 

sure is alot of motor work going on over the winter amongst people on this site!

can't wait to see what everyone ends up with.


anyone running or have on order a miniram III?


mine should be here monday morning.....:lala:

 

You tell me what you got ,ill tell you what i got! lol j/k First i went with the FB385, thinking i would switch to carb, but plans fell through so i saved for the MRIII. Then i upgraded the cam to the hot cam. Thats pretty much it. Full MSD ignition, Edelbrock Jet Hot coated headers, blah blah blah. Definately not the cheapest route. Wish i went for the short block but at the time i though i was just doing a motor swap, not upgrading it too! Oh well, can't change the past now. At least i can say i got the motor for under $4k, now its around $4200 plus shipping. So, you made your mind up on a motor set up huh! Later

 

yep, you should be able to guess for the most part what i'll be doing since i posted the intake!

damn that thing is expensive...a hair over 2,000 it's costing me for the intake, fuel rails, port and polish, and the chip to make it all work. it had better be the best thing since sliced bread for that price.

got a smokin deal on a accel 58 throttle body as well.

the full details on the engine, trans, rearend, suspension, brakes, wheels, plating, polishing, seats, entertainment, and a few other things will all be posted when the car is finished in 5 weeks.

a heck of a lot of work, hopefully it will be worth it.

 

Good luck with it all. If it is anything like the appearance of your car now, should be pretty damn impressive man. Good luck to ya! Later

 

No, I was not at Home Depot. I am curently waiting for my tires to arrive... FedEx webpage says that they are scheduled for delivery today.... they better hurry up!

Yea sure, maybe its not an actual ZZ430, but with the LT4 Hotcam and Fastburn heads, its a reproduction ZZ430 and will for the most part put out 430hp! So who gives a **** what the name is.... because its gonna be one hell of a motor!

Anyway, its not looking like the tires are going on today unfortunatly. As soon as they are on, we should meet up.... I'm free all week, then I go back to Rutgers on sunday. Keep us updated on ur MR ZZ430!

Kandied91z - You have one hot lookin car... and now ur doing all that work to it.... that's gonna be a 1st place show winner time and time again when it is finished. good luck with that!

 

I'll PM you, i should be working on it a few days this week. It will be nice out , just cold as hell. I believe it will not be over 30 for the rest of the week. I get in touch with you.
