Default My E-M Cobra

Picked up my E-M 460 from Florida. Found on CobraCountry site.
.030 over, Kaase aluminum heads, Holley 4150, Richmond and 3.73 rear end.
Just got a few miles in with her, then winter set in with a vengeance!

Concerned about low oil temps, and considering pulling the oil cooler.
I've been following threads here, and am concerned about oil that's not hot. Other than that, don't think I want to change anything about her.

Have you gotten it completed yet? Congrats on going with the big block..... my next engine project will be a 385 series stroker. I think your power level is just about perfect for a crazy street car. Call the driveshaft shop in NC and go ahead and upgrade to their level 5 halfshafts and stick some Nitto 325/50/15ís on the rear. Iím running a 427 Windsor with the Nitto 325/50/15 drag radials and a 4.30 rear gear with a T56 6 speed and it is an excellent street car in my opinion. I read about 385 builds all the time and my plan is 750hp/700tq..... I want to be able to pull it to 6000-6500 and run a hydraulic roller....figure thatís doable with some Kasse P51 or the new AFR heads and the right cam. Wicking up my Windsor with CHI heads and going the clevor route would be pretty awesome but it would never make the torque and would be much higher strung. Welcome to the madness!

My "new" 13 year old cobra is running a 460. Bought it out of NY. Guy I bought it from knew nothing about the internals of the engine. I pulled the valve covers and its clean and has roller rockers but I haven't tried to dig into it any further.

Car is 13 with 3200 miles on it. Hopefully I won't be taking it apart any time soon.

Will know better after a few runs in the hill country with the Texas Cobra Club at our annual event.

Hello everyone,
* I'm rebuilding a 429-460 / DOVE-A, year 71 I've been 2 weeks with it and I hope I can have a great engine in my garage, its state was never opened and everything was standard. suggestions from the experts to do with?
Is it 2 screws?
Thank you, and forgive my English, I live in Spain and I use the Google translator. sorry

That will be 2-bolt main caps. The typical wisdom is 2-bolt mains are good up to about 800 HP, so unless your plans are to go beyond that you don't need to add a girdle or go to 4-bolt main caps.

I've had a 460 for about four years, sounds great, runs great. Had a single plane manifold to start and it was terrible in traffic and low RPM. Went to a dual plane performer and the ET's are the same but is much nicer in traffic and at low R's.
