Am putting a '82 Chevy 454 into my '67 GTO(I know, I know, the purists are cringing!) But I'll never get 600 HP out of a pontiac motor...
Anyway, which engine mounts do I need to change to?
By the way, the car is completely Pontiac stock other than the new motor and tranny.

What are your goals?

He, who laughs last...

OK, sorry. Obviously you can get 600hp from a Pontiac motor. But let's face it, the 454 is the way to go for big power. Also, the options for parts are far more available and reasonable.
Back to the question, which mounts?

Big block Chevelle mounts will work, the holes in the frame are already in the right place so you won't need to drill new ones.

You can even buy them already installed in a Chevelle, where a chebby motor belongs http://forums.performanceyears.com/g.../icon_razz.gif

Nothing is real if you don't believe in yourself-Rocky Balboa

U'all can get the motor mounts from a Chevelle restoration parts place. U'all do what u'all want cus it u'alls car. As far as 600 hp out of a chebby well it costs a lot of money and so does a Poncho. I put a 427 in my Goat it 75 cus it was unusual and it was hard to beat a chebby. A 427 built would rev faster than a 454 and it beat a lot of 440's and 454 and 455 BOP's. Now that it is a norm I'm thinking of something more unusual like a 472/500 Caddy or a 400 with a 455 crank or just a nice 455. Take a 500 Caddy and a set of new alum heads and intake and a 850 Demon and a good low torque cam and u'all could win any burnout contest. To run with the big boys take lots of money but without the knowledge to tune it and the chassis and all 600 hp is nothing.

DRIVE IT LIKE U'ALL STOLE IT!

If you want cubes, try a 502 chevy..........

The only real difference in motor monts for Chevelle big block and small block is strength the hieght and fit are the same. They look different but it is a myth that there is any difference in hieth
