BBF project car.

BBF, consider this in the car if you want high milage but a fast car. get a quick change rear end. know what i'm talking about? you can swap the rear gearing relatively fast. this way you can drop 3.08s in for commuting/driving (and it'll still be fast with 3.08s) and put 4.11s in when you want to go out fucking around.

it's something to consider putting in and will definetly help with milage. dunno how long it takes to swap the gears though. by "quick change" i'm assuming we're talking about under an hour. guy i was in the Marine Corps with ordered one, but i got out of the military before he got the rear end for his S-10 with a worked gear driven 350. i think it cost about $1800 but supposed to be tough as nails and able to handle a lot of abuse.

I can change gears in a ford 9" in 2-3 hours. Its i a quick change rear end. The problem here is that the 3.50 rear end is my optimal gear for my car with this combination in the 1/4th mile. I need to be able to hit at least 130 mph near peak horsepower in 3rd gear (around 6500 rpm) with the converter slipping (running an auto remember????). Anything deeper than around a 3.20 rear end, with the modified engine, and the trans will try to drop out of overdrive into 3rd if the rpm drops below 1800-2000, at 60-70 mph. This will reduce gas mileage.

I understand what you are saying, but it does not apply to my application. I will be using a 3.50 rear end gear.

I like the look of the 4th gen camaros better than the firebirds honestly, but their both cool.

Ford 9" are like 92%, while a 12-bolt rearend is like 94-95%, true the 9" is stronger than the 12 bolt, but a modified 12 bolt can stand up to some hp and lay down more horsepower. The 9" is the budget option though.

395ci ? is that a bored and stroked 350 block?

AFR heads make some huge claims with their heads, check em out. - all were tested with mild cams, crazy torque curves too.

Damn CRAK pwoned

i'd have to see a gearing chart based on what gearing the trans uses. as long as it's dropping into OD at about 55 you'll be fine provided the torque converter doesn't have a high stall speed. that'd be kinda nice to drop into OD at that speed and be revving 15-1800 rpm at 70mph.

oh yeah, I'd keep the stock exhaust on

Mr. Gasket makes a Y pipe that fits behind the headers and has a lever you can pull which uncaps it. A mild sounding street machine turns into a demon from hell - your opponent wouldnt expect it.

 

[wtlftr]

yes, I agree..1800 RPM's at 70 mph

I plan on using the AFR research 205 cc mongoose head orby. There are some mods that will need to be done to it, but its a good foundation. I'm very familiar with this company, and have carefully studied flow results, and combustion chamber design of the varies heads available for the ls-1.

The displacement will be from using a stock bore ls-1 block and a 4.125" lunati crank.

I'm not willing to disclose what will be done to the heads though... this is not information that is in circulation on the net, nor will it be by those in teh know.

I plan on running 1 3/4" to 17/8" steeped headers, with 3" true dual x-pipes.

If one wants to run uncaped in this type of application you do not pull a lever, you get electric cutouts. You press a button to open them up.
