Big Block Buick

[Guest BigBlockMan]

Sorry guys i know its not a chevy but they are both GM so i figured it was better than in the ford forums. I am thinking about trying to put my Buick 455 into a Z. I was wondering if anyone had any ideas as far as clearance issues or anything like that. Maybe there is some sort of other Big Block that has been put in that could give me an idea of what i am up against. Any help would be greatly appricated.

having built a few 455 buick engines in the past I think youll find this info interesting. IVE never installed a buick in a (Z) but a 500 caddy has been installed as has a 454 chevy so its possiable (but probably not easy)

Thanks I am driving the engine right now in its orginal car (76' electra). You say it would not be easy, do you know of any of the problems faced when other big blocks have been dropped in?

I would imagine just about everything....

while theres nothing to prevent you from installing one in a (Z) youll need to custom fabriicate NEARLY EVERYTHING, the only problem areas I see are the engines WEIGHT 600 lbs-640 lbs and width which are both more /larger than the typical SBC engine

mmm...I miss my 430 (installed it into a 69 sportwagon that I sold because it was totally rusted away)

I have a 455 on the stand. I have been searching for the right Z for a few years to put this in. Keep me updated on your progress.

Although not a Z, this thread might be helpful:

for your information a 455 Buick with an alum. intake and headers is 40 lbs lighter than a stock small block Chev. its much smaller in physical size compared to other big blocks because of the short stroke and larger bore and more upright cylinders. i think most torque of stock GM big blocks. I have been known to be wrong ask my wife:rolleyesg

very wicked indeed!

Buick 455 is actually not much larger than a buick 350...it's a little longer because the bore spacing is wider (it's needed because of the 4.315 stock bore size...buick 350 has 3.800 bore) It's really a non issue anyway because a buick 455 is much much smaller outside than say, a VH45DE, and that's been put in S30's now.
