Hi Guys,

Just found this forum while browsing and have the same question. I have the Pontiac 400 (Texas car) with the 6X heads. Not sure on the 6X-4 or the 6X-8 but will know in a few days when I get to the car and have another look.

I have imported a 77 Transam SE to Australia in 1992 and have had it in storage since. I have done a conversion on the car to RHD with the firewall, brakes and steering all swapped over.

Not happy with just leaving the car stock standard I am about to strip her down and re-do the lot but my main concern in the engine.

What would need to be upgraded to get the 400 HP as mentioned above??? I would have to grab all the required parts on my next trip to CA which might be early in the new year.

Any help would be greatly appreciated with suggested parts and estimated costs to get the motor rebuilt and around the 400 HP mark. Maybe a good suspension parts store will be handy aswell in CA. Probably going to grab springs, sway bars and all the rubbers needed.

Note I have built several motors and will do most of the work myself.
Obviuosly all machining will be done at the shop, but I will disassemble / assemble the engine myself.

Thanks for your help.
