well you probably already know but i have an 87 camaro iroc z, and im wondering what they have for a rear end ratio stock, and what would you prefer for reasonable highway, but good ET rear end as a replacement. also, any rear ends from other chevys that will bolt right up?

thanks thats jsut what i needed. nice picture too im liking the carb out the hood idea.

 

Yah ... The Tunnel Ram Is Sick Huh? I Like It Alot. It's An Old Style Big Barrel Body. Paid $120 For It On Ebay. Check It Out Under The Hood ... http://cleanandsober.741.com/images/TRX.jpg .... Sick

 

i love how u painted it to match looks awsome. christ though what rpm's does that make most of its power? i would think way teh hell up there, and what cam are you running?

 

To Tell You The Truth Timmy ... I Haven't Got Comfortable Enough With The Car To Even Watch The Tach To See What It's Doing As Far As RPM's And It's Mounted Right In Front Of My Face LOL. It Loses Traction Quite A Bit And Keeps Me Busy. Been Shifting By Ear. My Best Time So Far Is 14.24 @ 97.32 Miles An Hour On Street Tires And Stock Rearend. I'm Saving Up For A Spool And Some Slicks. The Cam I Bought Out Of
Lack Of Knowledge But, As It Turns Out It Seems To Be Working Really Well With My Setup. It's A Speed Pro .468/.480 Lift .304/.287 Duration. Since I Bought It I've Been Doing Alot Of Studing On Cams And What Not And I Think I Should Have Changed Springs and Went With A Higher Lift. Oh Well We Live And Learn.

wow its power band starts at the same rpm as mine. what kind of cam are you running? like solid or solid roller, hydraulic/hydraulic roller?. your probably advancing your timing generously, so jsut look into a cam that matches your manifolds rpm band as best as possible at ADVANCED DURATION. 305's can be made to rev up to 11,000 rpm's, even higher, so i would put a solid roller cam in that baby, with an advanced duration around 270-290, and a lift around the lower .600's. that would seem to match a tunnel ram quite nicely. you will probably be sacraficing a buttload of bottom end with a cam like this, but when it does hit its power band it will be making awsome power. if you teamed this stuff up with some aluminum roller rockers, that thing will easily rev to 10,000. for a tire size i would recommend 295 50r15's, that is guessing that your wheels are 15 inches. the 295 50r part is the important part. my rear tires are currently 295 50r15's, and they give me awsome traction. they are not so much a drag tire, but if you did get drag tires in that size, your tire spinning would be a thing of the past, and they look damn good too. with cheap air shocks, clearence is not a problem at all, and you can adjust the weight transfer on your car slighty to help those launches.
thats not a bad price at all for that manifold, but ill save that for the next project car. im jsut trying to keep my car looking basically stock, which is why i dont have some honkin manifold on there. i wouldnt put that on a street car anyways, but i will be getting a strip car soon. good luck with your car it looks and seems to perform pretty damn good.

 

Heres The Stats On The Cam. Sick
Part Number - CS1062R
Brand - Speed Pro
Power Range - 2200-5700
Idle Quality - Fair
Valve Lift Int/Exh - .468 .480
Duration Adv. Int/Exh - 304° 287°
Duration @.050 Int/Exh - 220° 231°
Lobe Centerline - 110°

It fits small block Chevy 283, 302, 305, 307, 327, 350, 383, and 400 V8 engines except 1987 and newer engines with OEM roller cams. These motors are most commonly found in the Chevrolet Camaro Z28, Caprice, Chevelle, Chevy II, El Camino, Impala, Malibu, Monte Carlo, and Nova passenger cars, and also, Blazer, Suburban, and Chevy GMC GM General Motors light duty pickup trucks and vans.

It is designed for the street performance enthusiast looking to add a significant power increase with good mid-range torque and drivability in their street rod or muscle car. It has computer generated cam profile that significantly increases horse power, while still retaining a fair idle quality with only 3-6 lbs. of vacuum loss.

The Pro 3000 Series of cams from Speed Pro work best with the following components:

Axle Ratio: 3.20 to 4.20
Carburetion: 4 bbl
Compression: 9.0-1 to 10.3-1
Computer: Computer will require aftermarket chip
Exhaust: Headers with dual exhaust
Intake Manifold: Works best with aftermarket dual plane high rise intake
Transmission: Stock automatic (stall converter optional) or manual transmission
Valve Springs: Performance springs required such as the Z28 style I have in my other auctions

 

this seems like a good list... there are 4 different sections by year chevy caprice:
