I got it up on the highway with only the catalytic converter for exaust. It probably has enough power to pass someone, but once it hits about 50 its just about dead, then it shifts into 2nd somewhere near 60. The 425 just does not have what it takes to move an areodynamically challenged 2 1/2 ton car at 60mph up hills.

I can get ahold of a 472/500cid intake manifold. Im sure my current gaskets will be trashed if i take the 425 manifold off, so if it will make enough difference to make me want to spend money on gastkets, sure...

What about a bigger air cleaner box? I might be able to get one off a truck at an auto junk yard. I will definatley look into buying a 2nd catalytic converter for dual exhaust. Its just a matter of spending money for exhaust piping.

And i know the largest factor would be my differential. 2.8:1 standard (spins one wheels only). 8.3mpg town/highway combined with a 2.8 is bad enough, so i will leave that alone.

If i put a ricey exhaust tip on the caddy, i suppose i could get 300Hp out of a fart can, but i wont go there.


I am parking this car over the winter, so now is the time to fix the 8 track player. Any other things i will have to get started on ASAP.
