it is my personal belief that GM put a 'light' valve spring to prevent reving this high;
in doing so, it would help to garauntee that the engine wouldn't over rev the turbo ~ as overspool was a legitimate concern that they had, and this was even cited in the 'Stage 1' kit.

once the valve springs are upgraded the rev. ceiling should be safely raised;
the next thing to consider is where peak torque starts dropping off - if you're making peak torque to (lets say) 6,300rpm - then reving to 8k is of no benifit because shifting that high will put you past peak torque for the next gear...
Does this make sense?

The only benefit to high rev's in a smaller turbo is being able to hold 3rd gear in the 1320 haha

KMO43

Ya gotcha. but would the turbo over spin at high rpm because the oost falls off so fast

KMO43

or would it just start spinning so fast to try and keep up but just can't

I just noticed this;
I personally prefer to use more duration, and not go crazy on lift because of added issues...
I would ideally like to find something in the 224-226 duration & .410 lift area...
And then there's the fuel pump lobe...
I understand that this helps the guys running E85 - but it's of no real benifit to me, and if anything it's going to skew my RPD's fuel pressure readings, and mileage/economy which I use nearly every day...

I like this, but at the same time, I don't.

KMO43

would you go stage 1 or 2? How much power do you want? I want to get the lobe and injectors for safety

I would like to "play" with the Cobalt, but above all, I care about reliability;
I also have an old Firebird that I'd really rather spend money on at this moment...

IF I was to play wiith the Cobalt, I would do the following:
First phase (would probably all be in one fell swoop):

• #82 valve springs c/w titanium retainers
• cams; probably get them made by a third party with duration around 220-224 degrees (I reconsidered this), I would retain stock valve lift, and the stock fuel pump lobe, becasue I wouldn't be going too wild (stay under 25psi).
• Intercooler, probably the MPX becasue it has the best clearance, and seems to have the best fitmment

Second phase (some or all might never happen):

• charge pipes; ZZP's are probably my favorite's, but I recently found a cmpany that makes them nearly if not identical (might actually be ZZP's supplier) for cheaper.
• exhaust; probably MPX, because they are the best for clearance ect.
• intake; probably hte K&N SRI, because it seems to be the best option, as it doesn't skew MAF readings - even if it is technically an 'HAI' ~ but the flip side is that it won't suck up water!
• ZFR; because right now it's the best, and only 100% bolt in upgrade as far as I know... there are several that come close, but they all either need a BOV (and deletion of the recirculating valve), or different head pipe setup.

I'm actually slowly, but surely gearing up to work o nthe Firebird a this moment - some of the finishing details are what I'm chasing down right now;
I recently bought a new trunk emblem, and looking for a front bumper emblem...
other than big steel parts that are readily available (eg: floor pans) I am good to go at the moment.

KMO43

Wow sounds really close to what i want. only difference would be in order i get it and I really want the 7163 but if its not out around june I'll get the 6758

KMO43

what year is the firebird?

1970 Formula 400
'Carousel Red' paint
black standard interior
options:

• Rally Gauges with tach.
• Console
• AM pushbutton radio
• Power Steering
• Power Brakes

I bought it in 1995 out of rural Manitoba with a 400cid L74 'Ram Air III' (366hp) engine from another 1970 Firebird* and a Muncie M22 'Rock Crusher' 4 speed from a 1972 Firebird* (*=by the codes).

My Firebird was originally built with a 400cid L78 (350hp) engine, and a Muncie 'M13' 3 speed (1:286 built this way, and one of only two that I have come across since buying it).

I bought a numbers & date code correct L78 engine (which came from another '70 Formula), and a numbers & date code correct Muncie 3 speed (which came from a 1970 Pontiac A-body (GTO/Tempest/Lemans); these are apparently bulletproof, and geared nearly identical to a TH350 - which means better than any four speed).

I sold the Ram Air III a number of years ago to fund buying another car when I was in a tight financial spot, and have been stockpiling all the hard to find parts I could source that I knew it was missing, or it needed - the most significant of which was a pair of full (used) quarter panels that came out of Oregon & Washington state.

The only difference between the L74 & L78 are exhaust manifolds, carburetor jetting, and a camshaft.

Yup, I might like the car...

I could have linked you a cardomain page, but after that site screwed all their members over, I waited a couple months for things to get fixed - and recently gave up and deleted all my CD pages.

EDIT:

Here's a snapshot that I used to host on cardomain, from when it looked it's best (I got in an accident in 2004, and shortly thereafter parked it and started stockpiling parts) - I saved all the pics, and loaded them up to my photobucket account.

i think i have found my new colors.

i knew that mr.b cams needed a adj cam gear blue.

KMO43

Awesome I would love to restore an old car I am so interested in that stuff. Sounds like it'll be a gem when its done!

Whats that combo?
Can't get cam gears for the lnf

jrmotosports 88

stellar blue on top of pearl white. with a bright yellow, black and tvs charcoal metallic pinstripe

KMO43

Wow sounds complicated. how are you going to splite the car. at bottom of the windows?

KMO43

So the pontiac 400 is different than the sbc 400 right?

SylverSS/SC

iTrader: (3)

Yes, pontiac motors are different from Chevy motors

jrmotosports 88

actually it isnt complicated at all, i do this type of job for reason man. down the pin stripe line is where the split will be. i have a cool idea for the yellow line for when i go tvs. i believe i will put the live after death on the trunk and the flight 666 under the hood. now im excited!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

KMO43

No I didn't mean complicated for you to do just sounds like a very long name to describe all the colours. are you going to split it at the body line on the door?

KMO43

I saw the detail on your car at the show trust me I know what you can do!

jrmotosports 88

the pin stripe line is slightly above the door handle, so there wont be any issues there. in the end it will be more of classic look then im use too. yet still holding true to what i love.

KMO43

When will the wrap be done think?

back in the day, all the divisions had their own engines;
the original Chevy V8 (later to be known as the small block) debued the same year as the Pontiac; 1955.
The 1955 Chevy V8 actually used the Pontiac designed rocker arm as well as the rocker/pushrod/lifter setup(!).

jrmotosports 88

we are waiting for a company to pay us a large sum of money. then he will order the product. i believe that happens next month.


ON A SIDE NOTE!!!!!!!!! I WOULD DO DAMN NEAR ANYTHING TO GO SEE THE CRUE LIVE!!!!!!!!!!! I WOULD EVEN CONSIDER GETTING UNDER A DESK hahahaahahahahahahahahahahahahaha last tour ever. they will officially retire after this tour due to mick mars's condition. alice cooper to open. tickets go on sale i believe the 30th or 31st.




this is not to work safe guys^^^^^

KMO43

I really like that chrome on the silver looks sick
