Engine Size question

Hi Guys,

i´ve bought a 68 GTO.
there is a souped up 327 chevy engine in the car.

now i want a other engine.
i would take a 572 chevy engine.
But i´m not sure, how it fit between the inner fender, and i wont trouble with the steering...

What is in your 68 GTO for an engine?

Thanks for answer, Manuel

You could probably put any big block Chevy engine in there with the right frame/motor mounts. I have to ask, why a Chevy engine? Why not a Pontiac engine in your GTO?

Because in him is a 327 chenvy engine and a turbo 400 tranny.

When i want change to Pontiac hardware i must the engine mounts change too.
And a other tranny i need then.

You can put a Pontiac back in it. Frame mounts are easy to change and you could run an adapter plate to make the trans work or buy and engine trans together. The Turbo 400 is strong but the 572 will make a lot more power than the 327 that is in there so you will probably have to go through it and build it to take the power.

That said I have a BBC in my GTO and anything that will fit a Chevelle will work on your GTO as they are sister cars sharing the same GM A body platform/frame.

ALKY thanks for your answer.

you must know, that i have in my garage a 4l80e with TCI TCU and a first gear ratio like a 700r4.
when i take the 572 than the 4l80e work with it together.

So now the question is.....which 572 are you going with?

Also please realize that you should do some frame reenforcements when adding this much power. Specifically I would suggest a rollcage tied into your rear crossmember and frame. And I also recommend with an upgrade in GO that you also upgrade the WHOA and put some good brakes on your GTO.

For as much money as a Crate 572 big block and a 4l80e rebuid would set you back, why not build your own Pontiac motor? A 400 or 455 can easily be built up to give you all the power and ESPECIALLY all the torque you could ever find a use for. Even if you don't do the build yourself I feel like you could easily get as much out of a built up Pontiac motor as that 572 Crate Chevy engine, and probably for less money.

when i must build anything, i do it by myself, that´s no prob.
the tranny i have here, but i dont have a pontiac tranny or a pontiac engine.
because this i would take a chevy engine.

and here is a good offer:
572 CU in 650HP BBC Chevy Engine OnSale 1 Only Dart Splayed Blocks All New | eBay

pointiac parts are very rar here in Germany, but for the chevy engines it give a lot of repair parts.
