hey guys i searched this site and have been trying to find the stock times for my car but they cant be found... can some one tell me the 0-60 time and 1/4 mile time stock for a 85 camaro with a 305... its a berlinetta... not sure if it makes a difference or if there already a post id be glad for you to direct me to it... also i was wondering with my Lg4 after i put dynomax headers and cat back, edelbrock performer air gap intake, edelbrock performer carb and a comp cam... how much horsepower would i be pushing... thanks!

 

Auto Berlinetta, somewhere in the high 16's to low 17's. With the mods you want to do, low 16's-high 15's. If you get serious and add heads, you might break well into the 14's.

 

well here is the deal with out head's and a heavy cam that LG-4 will fall on it's face a buddy of mine did intake carb ingition and exhaust to and LG-4 he might be running all of 15.40's........
sadly out of the 305's the L-69 the LO-3 and the LB-9's are far better then the LG-4....

same car same gear's the LO-3 sadly run's 2/10th's faster then the L-69 witch baffles me cause the L-69 was rated at 190hp and the LO-3 was rated at 170hp........

But if iwas you I'd get a nice 400chevy .

350's blah yucky....

if you wanna stay 305 i'd just get a good healty L-69...

 

thanks guys im wondering what would be the best path to get into the 14's? and please dont say... get a new engine...

 

another question is you were talking about the heads... would i see any gains if a say just went to a junkyard and took the heads off of a z28... few qustions about this... do they have to be from a car with a carb or can it be FI also would i see a gain going from the LG-4 heads to maybe a L-69 or something like that.. also how much would it be?

 

I can make your LG-4 eat LT-1's and $hit L-98's...

but it's going to take some money and time???

it's going to involve builting the eing e up alot and get some new gear's......

 

If you're going absolute bottom dollar parts (I understand bro) I'd consider some LB9 heads, maybe port and polish them. And you'll definitely need a cam. I'd even consider a TPI setup.

Carb vs FI heads. I don't think there is a difference except for the perimeter and centerbolt thing.

 

ya u know how it is being 16 and having to insure a camaro... dont come accross alot of extra money lol any other good deal parts to improve performance... i mean im not trying to build an all out drag car... just a little more get up and go for my daily driver...

 

head's are very good move to update......

but i'd upgrade that wussy cam them engine's have wussy peanut cam's. a cam head's good start.


288*Dur 575lift cam some reworked l-69 or LB-9 head's will work.

Nice performer intake the airgap is too much.

600cfm carb or 670cfm TB if you go EFI.....4.10 gear's witch you can find at a yard....

Only thing you would need to buy is the cam and gasket's....
you can get a rear end with 4.10's al ready it i'm sure... head's an easy find....

some junk yard's have some nice $ss carb's still on engine's...

at the most you'd have to buy a cam and carb but those come used.....

worst case you might have as much as $800-$1200 in to it but more then likly less with good used part's...

I built a low 13second S-10 out of spare part's.. only had $750 into the whole thing and that inculde's buying the trck for $75 buck's

86 s-10 blazer 406,700r4, 4.56 gear's 235/70r15 pursuit radail's....13.40's......

I'd suggest watching the for sale board on this site. Most of the people on there have 4th gens. so whenever anything 3rd is for sale, you have more time to get in first. I've recently bought lt1 style tips, a 3" flowmaster cat-back, 28 spline axels, lowering springs, all for really good prices. Those won't really help you out too much, but if you can get all the little stuff for cheap, it would really add up, then you can have more for actual mods

 

Be careful on swapping heads. If your engine has small chambers and you swap heads on that have bigger chambers, your compression takes a dive, and takes hp and torque with it. You can check head casting #'s at mortec.com to check chamber volumes.

14's and decent driveability/mileage/reliability shouldn't be that hard. Good exaust, a cam with around 210/216 duration, good intake, tuned carb and ignition curve and a posi diff with 3.23 gears and you should be there.

Keep things mild with a small engine in a daily driver. Don't overcarb, overcam or get carried away with exaust sizes.

 

If you get 350 heads, you can always get them milled. I know a lot of guys that have 350 heads on their 305's and their compression is around 8-8.5:1 They never had them milled. Like I said though, some LB9 heads probably won't be hard to find.

Wait! In maybe 4 months, when I get my AFR's I'll have a set of L98 heads you could have for cheap. I'll contact you when the time comes to see if you even need heads still. I might even throw in the "Fellow 16 Year Old F-Body Enthusiast Discount"

alright guys thanks for the help just PM me or email therealchriskirk@ameritech.net when it becomes availible.

 

your best bet for cheap heads would be the lb9 heads from an 85 or 86. there 58cc heads and gave the lb9 9.5:1 comp. why i say 85 or 86 is because there perimiter bolts and 87 and up are center bolts which are harder to find stuff like roller rockers and valve covers plus if you have an older intake you want to use you wont need to modify it.

as far as a cam would go id say a lunati bracket master II with .458 intake and exaust lift. these cam and lifter sets cost about $145 but its worth it in my opinion. ive used this cam and lifter set in a LB9 305 that was converted to carb and it woke it up big time. i used a $30 set of crane ball end pushrods with this and the motor still runs strong with nothing wrong.

if you wanted to get a set of 1.94 intake and 1.5 exaust stainless valves and have the lb9 head valve seats cut to accept the bigger 1.94 valves.

headers are a must to. the stock exaust manifolds just dont flow good enough.

a set of full roller rockers not just roller tips will also free up some hp.

you might also want to look into an edelbrock performer intake and get rid of the heavy cast intake. i just seen one of these intakes go for $20 + shipping.

lightening the valve train and reducing friction frees up alot of hp and most of the stuff is transferable to motors with the exception of the cam and lifters. plus if you live in a state that dont do visual checks get rid of the smog pump and all the heavy crap that goes with it. lightening the car will get you closer to your 14 sec. goal.
