Blown Head Gasket
 
I have a SPC with a 427 Shelby Block stroked to a 484 with Eldeblock aluminum heads with studs instead of bolts does anybody know if you can take the heads off in the car, or do I have to pull the motor. Its the passenger side.

I seriously doubt you will be able to take the heads off without removing the engine. Look at the heads and figure on pulling them straight out about 5 inches to clear the studs. You'll be well into the fender by that point.

Head Gasket
 
I had the same problem with the left side 3 years ago. Pulled the engine. You might be able to pull the right side head in the car, but personaly I wouldn't try. I decided to just pull the engine and use the occasion to detail everything. Even replaced a few gaskets while it was out and on the engine stand. Good luck. Bob

Pull the studs from the block, then pull the head(s).. Are the studs allen head?

I made a stainless steel stud kit for the intake on my Pond 482. I have to do the same thing (for a different reason) to pull the intake.

Just curious, how do you know it's a blown head gasket?

Snap-on or matco make a stud remover
 
flipscobra Snap-on or Matco make a stud remover socket for your problem. If not,try matco. I think Sears only goes to 1/2" and the studs are 5/8" or 11/16" size. If not you can always lift the head with a small block of wood and remove the stubs with a vicegrip or double nut the tops. :eek::o Try not to damage the studs. Some studs have allen head tops, Mine didn't. Other wise it's motor pull time. This may be the best way. This will give you time to check the wholw motor over. How did the head gasket blow??:confused: The L/S should get replaced too, IMO. They where both installed at the same time. This might save another repair or pulling the motor again deal. %/ Rick L.

I am not an expert at the Shelby block or the SPC but I do believe that the studs go down into the block Which will make thema good 8 or so inches longer than regular studs. I can't pull the heads or the back studs off my Contemporary the a Cleveland. I end up leaving the back one in with the nuts on them and pulling the head with the stud hanging in it. With the longer studs of the Shelby block I would say its motor pulling time.

Another vote for "just pull the motor". We pulled the motor out of one of our local Superformance's (SPF) in about 3hrs with hand tools last month. My experiance has been sometimes you spend less time and aggravation just pulling the whole thing out rather than trying to work around things ......IMO.

good luck,
Mike

Thanks guys for the info. As to how do I know its blown, is you can hear it. An you can see a little oil coming out between the head an the block. Its been leaking oil there for about 3 months, I should have retorqued the heads then but didnt, dont think you can retorque them with the motor in the car. Thought about undoing the motor mounts an shifting the motor to the drivers side, an then pulling the head. Has anybody tried that.

I have another question, when yall pulled your motor on your SPF did you cut it loose at the bell housing or the transmission.

RICK LAKE 03-04-2008 06:16 AM
Bell housing is easier
 
flipscobra Unbolt the bell housing and install a jack under the trans to lift it up alittle when pulling the motor. Make sure you have the car on jack stands. Heavy rap the frontend of the car with moving blankets to protect the paint. I missed the shelby block thing, I have gotten the head off in the car, but it was a real pain in the a$$. :eek:Pull the motor and do both sides. What head gaskets are you using?? Felpro #1020's. I have not had to retorque them after running the motor. I do run Hi-tac on both sides of the gaskets. I also do step torqueing of the head studs, and let sit for 5 minutes before doing the next torquing step. That Aluminium motor is going to move about.0015" with ever heat cycle. Over time you will get leaks. This is why I use sprays on the headgeaskets and surfaces and RTV on all other sealing surfaces. Go luck. Rick L.
