The only thing we did was swap in the 42 lb/hr injectors and correct the tables for them and the car went 318 rwhp and it idled like a champ.Darren Quote Selected
Cobra Engine Craigslist Score! Reply #31 – April 12, 2013, 12:16:02 PM Got some things done yesterday. I sold the cobra intake manifold and 24lb injectors for $300. Gonna put that money toward some 42lb injectors and a MAF. I was pretty happy to see these beauties when I pulled the valve covers.Double valve springs with Crane rockers. The motor is super clean inside:)I stripped the flaking paint off the valve covers and painted them.I stripped the cobra motor and SO motor down to the long blocks to swap the intake, 70mm TB, timing cover, water pump, distributor, and accessories.cobra pump(top) SO(bottom)Gonna be working on painting the block, obtaining new, gaskets and dressing the motor today.

Cobra Engine Craigslist Score! Reply #33 – April 13, 2013, 11:12:47 AM I would get a different intake if you could. The stock lower is holding you back unless it's been ported. Those valve springs are actually stock but they look to be in good shape. You should paint the block/heads while the engine is out. I like the color on the valve covers. I think it would look good on the whole engine. Quote Selected

Cobra Engine Craigslist Score! Reply #35 – April 13, 2013, 12:04:13 PM Found this on one of the Mustang/Cobra sites so I am not 100% sure if it is all legit but it has been posted several times on the Cobra sites and no one seems do doubt it:Cobra Engine/Trans Specs:The Cobra engine was under rated at 240bhp from the factory campared to the GT's 225bhp and was only available with a 5 speed and 3.08 rear end gears.Cast iron GT40 headsCast aluminum Cobra intake manifoldCrane 1.7 rocker arms24lb fuel injectorsCobra specific ECU (computer)"Cobra" stamped valve coversEngine oil coolerFront mounted power steering fluid coolerLightened flywheelPhosphate coated transmission gearsUnder drive water pump and crank pulleysCobra specific camshaftCam specs: Duration: 227°/Intake & 270°/ExhaustLift: .485/.485 Intake/ExhaustLobe separation: 118.5°Alot of the other sites stated that the valve springs are actually a spring with an inner damper as the cast iron GT40 heads have to be machined to accept true dual springs. For the most part the springs of choice for these heads are here:http://www.summitracing.com/parts/TFS-2500100/My advice would be to get the TFS spring kit and install it now because having to do it later will cost a lot more $$$. I've never been able to assess springs by appearance, they need to be checked by a machinist to see what the seat and open pressures are and from there you can say whether or not the springs are good for the application or not. They do make spring testers that the average Joe can buy but most of us are not checking spring pressures enough to warrant such a tool especially if the heads are already off the car.Darren Quote Selected
Cobra Engine Craigslist Score! Reply #36 – April 13, 2013, 01:22:18 PM I did end up painting the block and heads last night. Also swapped over my fox timing cover and water pump and a new front main seal. As for upgrading the springs and intake, It's not in the budget for now. I still need to buy a clutch, injectors, MAF, and megasquirt. I need to get this car back on the road ASAP. I drive 2-3 hours a day and my truck is killing me on gas. Note the cobra's timing chain. It's a single wide chain as opposed to the double chain on the SO motor. Also the oil cooler ahead of the filter that ties into the cooling system. Quote Selected

Cobra Engine Craigslist Score! Reply #38 – April 13, 2013, 03:44:59 PM Could you swap on a new chain while it's apart? It's easy to do right now. Quote Selected

Cobra Engine Craigslist Score! Reply #42 – April 14, 2013, 04:16:04 PM I just ordered the clutch. Once that comes in I can drop the motor in. In the mean time I will probably make some solid engine mounts out of the old ones. I'm out of money this week, so injectors and megasquirt will have to wait till next week. Quote Selected
Cobra Engine Craigslist Score! Reply #43 – April 22, 2013, 01:06:47 AM This is how I plan to run my belt. just running an alternator and a water pump.Cleaned up my distributor. I think I'm going to ditch my home made turbo header on the passenger side and make a new one out of this stock header. It will be a lot easier to get the bolts in and out. I'm also changing my standard V-band s to the kind that have an interlocking male and female so they wont leak under high pressure. Quote Selected
