Big Block Engine mounts

[L78Kiwi]

Hello, Thanks for all the responses. The sub frame is a small block frame.

Let me give you a little history. The Camaro is a genuine 4K car it has not been on the road since 1970. The first owner had an accident which destroyed the front end. The second owner used the car for parts and the third owner began restoration. The third owner used the frame and front sheet metal from a 327 car.

I am the forth owner. I am trying to restore to the car as close to factory as possible....the 427 was the closest I could get to the original (rare as rocking horse s&*t) 396 engine.

So if I am correct the summary of the above would be that I need to take Plum67 advice to get a suitable fit?

I just want to clarify, when you say the cross member for a BB car is different from a small block car, are you talking about the front subframe assembly (as inclusive of front suspension etc) or the cross member for the gear box?

So just to really make you all roll your eyes.....and think what the!

Because of the engine change I also decided to use a Tremec 5 speed. This was supplied with a gearbox cross member. Ordered for a 67 BB car

So as I originally said, with the current 69 motor and frame mounts the engine is sitting forward on the frame to the point where there is not enough clearance between the back of the frame cross member and the sump to allow the steering arm to fit between. The gearbox cross member is also sitting behind the isolator mount on the gear box by about an inch. In summary it looks like if I can shift the engine back on the sub frame by about an inch I will get the engine to fit with enough clearance for the steering and line the isolator up with the gearbox cross member. Given this it seems logical to assume the engine mounts are the problem

But given the additional information will Plum67 solution still work? If so is there any other possible clearance problems I need to be aware of such as engine to firewall or engine to radiator ? (I do have a short water pump)

Thanks again for all the advice so far and I look forward to your further generous assistance
