Hey everyone, Haven't posted in a while, been busy thinking about buying a fancy pants sports car, but then it hit me. Why don't I just use the money I would have bought a sports car with and instead use it for the Riviera! So now this is where I need all you experienced full=sizers out there for some opinons and help. I wantto take my 430 out what should i put back in? Should keep the the engine and just heavily modify it. What would I need to make it 400hp plus, would i need a new rear end?transmission? I saw some crate engines that were 400 hp plus for not a bad price. There was a Olds 455, and some GM preformance engines for around 8 grand. What do ya think? Wold apperciate any help. Thanks
I would keep it all Buick and drop in a 455. Car Craft did a big block shoot out a few years ago and for just shy of 8 grand they built a Buick 455 which made 555 hp and 570 ft.-lb. naturally aspirated. A lot of the major parts came from TA Performance, they have the full article along with price list on their website. Good Luck with your project!!! :beer
Another source. trishieldperf.com/engines If I had the funds, Jim is the man I would see for a turn key engine.
The Car Craft article is at the very bottom of the TA Performance's web page (taperformance.com) under the tag 'see the 2001 Big Block Winner'
How would i go about getting one of those 455 from TA performance, is there an e-mail or phone number I can use?
The TA Performance info and order line is (480) 922-6807. Also on their main page you can download their 2007 catalog, in PDF format, which details everything they offer.
Thanks, another option I have is ripping out the 430, do an overbore and upgrade everything, would that be cheaper or as good as buying a custom built 455? What do you think?
455 Blocks are cheap. There is no need the weaken a 430 and take a chance it may not go the distance to 455 without getting too close to a water jacket.
I saw on the P.A.E website they have 455 and a 573! Would either or both of these engines fit in my 67 Riv, are the motor mounts compatible? And does anyone know how much these blocks go for or any place that sells just blocks?
The blocks are all 455 blocks. A special crankshft is the reason for the difference in cubic inches. You do not want to pay for that mod. You can buy a used 455 engine off the Board in the for sale section. If you want just a 455 block that has been inspected try the owner of this site: www.trishieldperf.com Jim@trishieldperf.com
Also, would a olds 455 be compatible in my car? I also found a 1976 Buick 455, is that compatible with the 67? What are the specifications for a 76 455?
The Olds would require a lot of work to make it fit. The '76 Buick 455 will work, but from a performance standpoint most prefer to avoid the '75-'76 heads when considering power-adding upgrades. Devon
So they are not desireable, what year is, and are they available? What is the difference in a 75-76 compared to the other years?
See http://www.v8buick.com/showthread.php?t=120037 as I mentioned in the other thread you started. Devon
large, open chamber heads and hence, low compression. the 75-76 blocks are considered the best 'base' for a performance build up ( you'd throw the factory heads away and buy some aluminums ) but for your purposes ( sub 500hp ) you might as well get a 72-74 with the larger 5/8" oil pickup of the later blocks and the 71cc head/piston combo. I also found a 1976 Buick 455, is that compatible with the 67? it uses the same engine mounts and accessories as the 430, yes. aside from the bore size and shape of the combustion chamber they are very close. Fly in a straight line of course. flying in a straight line does not exclude flying around corners.
DaWildcat, I saw that you have 10.8:1 compression on pump gas, what kind of gas do you use. I'm trying to determine the best compression for street, but still have lots of power, using let's say a 1972 455, what would you recommend?
