Question? Will the stock crossmember and transmission mount work with the Lq4 throttle body?

What does a transmission mount and crossmember have to do with a throttle body?

If you mean will the engine fit with the stock crossmembers and the LQ4 intake clear the hood then yes. Its been done several times.

I’m running the TBSS intake with the stock hood and a 4L80e transmission with no cutting to the floor pan. Trans crossmember had to be moved back and modified. Some people say you can flip the crossmember around to work with the 4L80 but it will depend on what engine mounts you use. I have everything detailed in my build thread for my 78 Nova down to the part numbers I used for what parts.

Thought I heard that even the top cover of the truck intake will fit under the bottom of the hood by about 1/2”, but haven’t tried it… yet.

Can anyone confirm the Truck intake will fit under the stock '77 Nova hood?
