Alright, I've never been to a track before to race, I dont know what to expect. My car isnt legal yet *no insurance/registration* so im just trying to get an idea as to what my car is made out of. I have asked this question a few months back and only got a few replies saying that I was lacking information.

Here is every bit of information I can throw at you about my car:

1979 350 bored .30 over. 4 bolt mains

Stock crank/rods/pistons

218 intake@50 224 exhaust@50 462-ift 469-ex 110 lobe seperation <--camshaft

Goodwrench 350 heads, garbage, BUT they are gasket matched, mildy ported, stock rockers.

Edelbrock Performer RPM intake manifold. Square>Spread adapter plate w/non cc qjet

Stock coil / 8.5mm wires

Headmen headers, shorties w/y-pipe.

Im assuming I have 3.23 gears considering I was never told that they have been changed.

When I bought the car the guy told me that a shift kit was installed on the 700-r4

Stock steel driveshaft.

Iroc-z rims, dont know exact tire dimensions.

Ac system deleted totally. No emissions equipment.

Any other information I could give out to help you guys determine what I would run in a 1/4 mile?

I'm hoping for AT LEAST mid-low 14's, my friend jim has an eagle talon tsi that I need to spank, he runs 13 1/2s

 

I'm going to guess mid 14's

 

mid-upper 14's. you need to know more about the car than you do. find out what gears are in it as well as the EXACT tire size...and find out how much it weighs.

 

Untill I find that data out, what do you think my HP rating is? Im guessing around 250?

 

hmm, you've sparked my interest... when are you going to run it and find out?

that's the compxe262 cam right?

haha, mwnova is all about getting traction. Tire size, diff ratio, etc... I'm more about motor. know what compression ratio is? those aren't stock piston, if it's bored .030"... So if they're rebuilder pistons, if the block wasn't decked, if you are now using a composition style gasket, and if you have done any grinding in the chambers of the heads (all of these are fair guesses), your compression ratio might be kinda low.... Not a power guess, but more of a "if you're disappointed, here is one place to check, for possible improvements..."

oh, tire size is an easy one to find out.... not like you have to pop the cover to find that out

finally, one more, more of a greedy question, as i'm tweaking my q-jet now... How is it set up? Know the rods, jets, or secondary side of things there?

 

I have a compresison testor, I just havent used it yet because I dont want to be dissapointed with the results. Plus im kinda lazy :\

One of the pistons on the block was stamped with ".30" so they arent stock, I forgot about that. But they looked stock. They werent anything special

The engine I have now was originally in a 79 vette that my friends uncle bought new. He then put a 454 in replace of the 350 and put it in the blazer. He used the blazer as a plow truck so thats why he bored it out and rebuilt it. So he may have decked the block, I'm not sure. Also, I used the torque converter that came with the engine. The torque converter that was on my original engine was all rusty and nasty looking, this one that was in the blazer was light green and looked just kinda dirty. I used the one that came with the engine, I dont know what stall it is.

The q-jet is as far as I know, stock. But it probably isnt. The engine was replaced by the 2nd owner before me of my car. It was a goodwrench 350 with stock goodwrench heads and stock gm q-jet intake manifold. The q-jet was non computer controlled. I have never cracked it open myself and im a bit worried to try to, afraid ill mess something up. The engine that came in my car stock was a 305 Im pretty sure, so they had to have done something with the qjet. My moms boyfriend says he has a qjet in his garage in michigan that came from georgia when he lived there that was fully tricked out, he said something like he got it from a guy who kept its appearance stock but did everything possible to make it better. I dont know what he means by that, ill check it out when I get my car legal, im skeptical.

and yeah, its the xe262.

 

Hmm as it sits, probably mid 14s, not very fast.

Get a good carb, good slicks, good gears and a good converter along with some LCAs and LCARBS, and you could see it go a second faster.

 

a compression tester won't tell you what your compression is, just what your cylinder pressure is. Meaningless for what I was asking, but it will tell you if the engine is in ok shape.
if your q-jet runs ok on the motor, without bogs, idle issues, etc, I would leave it alone. Maybe check what hanger and secondary rods are in the carb.
when is the car legal to drive? have you ever driven it yet?

 

lol, you can have all the engine in the world, but if you can't get the power to the ground, my 305 will spank you any day of the week!

and not ALL rebuilder pistons put the piston .020" down in the hole. you'll have to check that with a feeler guages and a straight edge to find out the piston depth.

ps, i love doing engine work and building things and finding out c/r and whatnot too, but the i've just made it a habit to set the car up for power before i start throwing more motor at it.

 

Using www.virtualengine2000.com simulation software, I get a estimate of 311 flywheel horsepower and about 13.8 in the 1/4. In reality, it will probably take at least a few visits to the track to perfect your launch and tuning to get into the 13's - from my experience, there will be plenty of fine tuning and bugs to work out. I also guessed on vehicle weight and compression ratio (I used 9.6:1 for a iron head)

 

thanks guys!

You know, before I owned this camaro.. the only car ive ever worked on was replacing head gaskets on a 93 cougar with a 3.8l v6. I have never been formally trained on how to work on cars, and my dad is a complete moron when it comes to cars too. This has been a huge learning expierence for me and all you people here are truely the ones responsible for my car running now *well i mean, i did all the labor " But seriously, You guys are awesome. The more and more I work on this car the more I have an understanding on how things work. The only part im confused about when it comes to cars are the transmission and the carbuerator. I'm never going to stop dumping money into my car, its too rewarding.

Matt, your car will spank mine any day of the week, im aware of this. Maybe one day down the road ill pick up a 200 shot and not let you know, then drive down to your local track, and race you for pinks *you still would probably beat me, ***hole, haha*

So im doing pretty good considering my lifes expierence with cars. My car is a giant toy to me that I can upgrade and make faster.

I already have a basic idea as to what to buy next.
1. holley 750dp that I know of for a 150 bucks.
2. 4 inch cowl glass hood
3. 3.73 or maybe even 4.10's
4. better fuel pump
5. raise the compression
6. new heads
7. 1.6 rockers
8. new cam
9. full msd ignition
10. new torque converter *that will be a PITA to replace*
10. bondo/paint

All in due time, I have a ****y job right now too. Only making 6 an hour without taxes taken out *sub-contractor* but that sucks because ill owe the irs a crap load of money come tax time.

Once I get my car legal im going to school and getting mcse certified *highest computer certification you can recieve* Once I get certified, then ill be making some serious cash, and of course, all of it will be dumped into my third gen.

All in due time.

 

this is all contingent on the idea that i won't make my car faster....yeah, that'll happen lol!!! i'll be fabbing up the beginning stages of a single hairdryer this winter....

 

rhamm1320:
How do you like that software? Do you have the standard version or the professional version? Have you checked it against a know engine (one that has been on a dyno)?

I bought the Comp Cams CamQuest software and it stinks. It is not at all what they advertise.

 

yeah well uh... my uncle just called me and said that he just bought me a new engine, I asked him what it was.. he said its a chevy 572.


uh, im not lying.. *cough*

 

lol

in all seriousness, those 572's are WAY overrated....i plan to make more power with my 305 than those do outta the crate...now with some work, those things can be sick!

 

Going to get more than 2 HP/CI out of your 305, eh?

 

hehe, yep! not n/a though, won't happen without a power adder. i don't want to start talking about it too much, cause it'll take me a little while to get it all together, but i'm planning a single turbo system right now...

 

I use both. The standard version is good for 'quick' runs - only takes a few minutes. If you put accurate info in, the results are pretty close.
