It goes without saying that you will absolutely need to upgrade the F-body drivetrain. That means a built trans TH-350, TH-400, 700R4, Powerglide and a stall matched to your cam specs and needs. Or of course a built manual with a good clutch.

I've tried to use the best products available and I've also looked at areas to save money. As long as it looks good, runs and moves I'm not in to the show side of it.

I'll go a head and list the thing you'll no longer need thats currently on your car:
PCM
WIRING HARNESS from engine bay.
GUAGE CLUSTER, you can use it but I think the new guage route is better.
HVAC, you can keep it, but you won't be able to get to spark plugs #6 & 8.
STOCK HOOD, maybe if you have a low intake but I doubt it. I figure atleast a cowl hood.


Things that you'll need to purchase before getting started:

Motor, oviously
K-member: BMR-Fabrication & Sphoon have BBC K-members (both sponsors here)
Carb
Electric Low Pressure Fuel Pump
Fuel Line
Fuel Inlet Line
Fuel Pressure Gauge (mounted under the hood.)
Hooker Headers 2455 or a custom made set.
Air Filter/Housing
Radiator, stock LT-1 or LS-1 can't handle a BBC,
if your doing a SBC swap then they will work.
Mini-Starter.
Starter Wrap. The headers are close and it'd be embrassing to have your starterseize up and be stranded somewhere.
Distrubor, Spark Plugs and Universal Wires
Spark Plug Wire Wrap, I ran mine unber headers and behind the engine to the dist.
Guages: atleast replace all the stock guages Speedo, Tach, Oil Pressure, Water Temp, Volt, Fuel Level
MSD 6AL or better


I only recommend taking the engine out and putting the new engine it through the bottom of the car.


First thing to do is pull the engine and trans to get those out of the way.

Next go ahead and get rid of the wiring harness thats in the engine bay, it runs inside the car on the passenger side. Unplug it and tape off all unused connections.

Go ahead and take the windshield wipers, black plastic cowl off. Just undo the motor in the center of the car and set it back against the firewall.

Before putting the engine in the car you'll need to trim the cowl area, How much depends on your intake, distribitor and your own choice. If done right the distribitor can be in its normal location and also be pulled when it needs to be changed. You'll have to take the cap off first and then the dist.
Here's some photos of my cutting.




Check fitment of the K-member with your car before attaching the k-member to the motor.

With engine on the engine stand attack K-member to the engine. Nows the time to go ahead and put spark plugs, wires, wire sheild, starter, starter shield water pump, alternator,headers, pullies and power steering pump to the motor. Its better to do this on the engine stand than to try this in the car.

Now you can mount the a-arms and shock stuts. Now support the engine with an engine hoist or something of that manner. Go ahead and hook up flywheel or flexplate. Nest do clutch or torgue converter (which ever applies to your application) then hook trans up to motor. Now you can put some support under the back of the trans and a arms. Now you can hook up your trnas dipstick and oil cooler.

Next step you'll need some help. Place your whole assembly (motor with headers bolted on, k-member, a arms, trans) under the car. Get everything lined up and you can lower the car back down and bolt everything up. In the picture I have I didn't have my headers on because I was checking overall fitment. I raised the car back up and put my headers on.



Once you've gotten this far and everything is bolted up. Take a break and look at your car for a while. It'll never be the same. Its a BBC 4 gen now. Now for the next few weeks or month you'll get to do all the same details. That will depend on time and budget. But congratulations if you've made it to this step you well on your way to haveing a nice BBC Camaro
