1970 455 Riviera?

[flip888]

I was looking through autotrader and i came acrost a 1970 Riviera with a 455 motor in it and i was wondering if this car has a lot of potential in the 1/4 mile. I was told that theyre very heavy (4000 lbs?) and not too fast stock (mid 15's?), but with that big block could i get enough power to make this into a 12 sec. car without spending too much? And about how much would it cost if i could do most of the work myself?
Oh and is the 455 basicaly a 454? and could you tell me what hp/lb-ft this motor makes?
Thanks.

Nope,back in those day's each manufacture were engine specific.In 1970,olds had there own style of 455,Buick's 455 was different,Pontiac's 455 was different and Chevy's 454 was different.
Buick offered 3 different HP ratings in the 1970 455,350HP,360HP and 370HP.

Engine ID code for a 70 455 is SR for a 455 350HP , SS for a 455 360HP and SF for a 455 370HP and they all had 510 FT lbs of torque @ 2,800 RPM

So it would be pretty hard/expensive to find performance mods for these?
what other cars did the 500 or 472 engine come in?

Here is a search from Yahoo on Buick 455 motors

The 472 and 500 CI motor's are from the Cadillac's
