i just bought a 83 camaro with a 460(454 bored) and i have some questions im new to american cars,im looking for a 6 speed tranny and a efi system and a rear end with possi and prefferably disc brakes...but i dont know what kind to look for if anyone can help it would be much appreciated....ive also heard that there is a company that does all wheel drive conversions from the syclones/typhoons/awd astro's/awd bravadas....any info would be great of any ideas anyone has for some reliable power i would love to hear them
thanx

 

I haven't done this personally, but I'm familure with what you have. The six speed trans you are looking for is a T-56 and is found in many 4th gen F-bods. The bolt pattern is the same for Big Block Chevy and Small Block Chevy. After market EFI systems for BBC are plentiful. You should have no trouble making a decision on one from any of the big warehouses, like Jegs or Summit. All 9 bolt Borg Warner rears in America have disk brakes and are stronger than the stock 10 bolt. They were available in 82-92 F-bods. The 10 bolt rears out of 4th gen F-bods also have disks and will bolt up to your car. However, if you are making good power and want a reliable rear then a 9 inch ford or a 12-14 bolt Chevy can be ordered to fit into your F-bod. Look to spend lots of cash.

 

i need a rear end with possi and disc brakes

 

All BW 9 bolts have cone type posi, and I believe that quite a few 4th gen 10 bolts have disk type posi. Just do a little web surfing and some actual research.

 

FYI, Some of the Borg-Warner 9 bolt rears did come with drum brakes. They aren't real common but they do exist.

 

With a big block, you're probably gonna need a 12-bolt or 9" rear.
Look at Strange Engineering or Currie Enterprises for bolt-in units.

I've been running a 3.73 geared 9 bolt for 4 yours now behind my big block with no problems.

Hey 88 427 Camaro, How much did your swap cost and I know this is a silly question but is your Camaro street legal?

 

and 88 427 camaro i noticed on your web site that you are running low 12's, don't get me wrong but that seems to me you should be faster than that, whats holding you back is it the weight of our cars is so much??? please don't take ofense i would love to have your car

 

It all depends on how much the engine is built up. A low 12's big block is mild when compared to a low 12's small block.

 

i have #781 heads for my bbc, if i put the right cam in it a 3.73 rear and a t56 would i be able to get in the 11's on pump gas and still be streetable?

 

Swap cost? Never added up the reciepts but I'd ~5-6k including all the little stuff.

Faster? 1) - It's heavy 2) - It's only a 2400 converter. 3) Like Stephen said, it's just a mild 87 octane, factory iron head, dual plane intake big block (500hp) in a heavy car and yes it's street legal (at least around hear, ie no emmisions).

gotcha thanks but does any one, know anything about #781 heads??

 

Thanks I might have to move to Minnesota for a little while.

 

781 heads are very good oval port castings. If you're looking for BBC oval port heads you either get 781 or 049 castings. Do some port and polishing and have the larger 2.19/1.88 valves installed. Make sure you know what cam you intend to use before getting any machine work done. If you need larger than stock valve springs you'll need to have the spring pockets enlarged.

I originally had 781 casting but broke the heads off a couple of valves and destroyed the heads as well as a couple of engines. I now run Merlin oval port heads.

I totalled up the entire cost for my engine. Everything needed to drop it in and fire it up. Ignition, exhaust, fasteners, gaskets, brackets, carb, water pump, aftermarket heads, "everything" and mine is now worth close to $12,000 Canadian.

When I built my first one I budgeted for $5k. I had it in and running for $8k.

The main cost for the engine isn't very much but it's all the extra's required to make it run and fit in the car that adds up.

I was originally using 92 octane pump gas with no problems but have switched to VP fuels C12 this year. The car drinks around 5 US gallons (20 liters) during a race weekend and I get about 12 passes down the track for that. I may do a 92 octane/C12 mixture to help keep the cost for fuel down.

 

ok thanks

 

Most street driven big blocks are grunt machines and typically are not revved past 5000 rpm. A 6-speed tranny is designed to keep rpms in a tight band for more high strung engines. I would personally use a 5-speed or auto tranny with more gear spread to use the natural mid range power band of the big block. I would also use fairly mild rear gearing to once again let the engine use it's natural grunt to pull the car. This, of course, is lousy advice if you're big block can wind out the rpms.

A Borg Warner 9-bolt in good condition will likely serve you fine on street tires and street suspension. The weakest link will be available traction. Getting aggressive with the suspension and tire setup to get a better launch will put you in jeopardy. Just try a 9-bolt and if it works then you saved money. If it doesn't... oh well... time to upgrade.
