IMO it would be the 427. The 454 was good but the 427 is better 😀

Every engine has its strengths and weaknesses.

I chose the 425 Olds over the 455 due to the rod to stroke ratio. The 425 will typically out rev as well as create more HP than a similar 455 but loses to it in the torque department.

Now my 455 is a bit of a combination of the two, using the 425's crank, offset ground back to the 455's 4.25" stroke using a BBC 2.200" rod journal size, 6.990" rods and custom pistons. A little bit of the best of both worlds. 😉

My choices:

Olds 455. I'm biased, what can I say? My Olds ****in' rips.

Cadillac 500. Bone stock = 550 ft. lbs. = Awesome.

I'm sure I will get cyber slapped for this question but aren't all 455's made by BOP's the same?

 

[Blake442]

OH sh*t SON!! :lol: Now you gone and done it!

All three are totally different.
The only parts that interchange between the three are distributor caps and thermostats.

Everytime I look at the things I think they look the same. I like the 455 rocket motors. Had a buddy with a 442 and he would do a burnout on a full tank and be almost empty at the end of the show. I thought mopars were gas hogs lol

I'm a Pontiac guy but I know the Buick 455 is the lightest of the bunch and can be built for awesome power.
