Due to a cracked cylinder head, i decided to overhaul the complete engine.
Couldnt help myself for adding some 'performance' parts while i was at it.

1971 GS 455, Stage 1 with F1C Procharger
Rich's 71 GS after replacing the D1 procharger with a bigger F1C. Some fine
tuning to be done yet, and then off to the track.
The car was mid 11s on 17" drag radials before.
1971 Buick Riviera 455ci engine rebuild start up
For more information on this engine build please go to:
This Buick 455 came to us with a distinct knock from the bottom end, it had
been rebuilt 2 or 3 times by others but was still knocking and suffering
with low oil pressure.
Normally we do not remove and fit engines but this time we made an
exception, we removed the engine, stripped it and cleaned all parts,
decided which new parts we needed and when they arrived we set about
getting this engine as perfect as possible.
After a lot of hard work we got her finished and installed back into the
1971 Buick Riviera.
9 Second Buick GSX Stage2 GS Stage1 9.51 @ 140
We originally built this car with Frank Urbinati back in 1996.It debuted at
the GS Nationals where it won the GS Pro Street class races. It was also
the 1st GS Pro Street class car to break into the 9's at the time.Thanks to
Frank this project came to life. Fast forward to 2010 and the car has been
taken over by Bob Ortolani,the car still looks great and Bob decided to
bring it up another level. We were happy to have the car come back to our
shop and to have the opportunity to work with Bob and put together the new
powerplant. The video shows the results of our 1st day out to tune the
engine. The 1st two passes were shakedowns to check fuel/oil pressures and
get a feel for the new combo. By the 3rd run we had posted a 9.62 @ 138
hitting the 7100rpm rev limiter chip! The 4th run was a 9.52 @ 140. On the
5th run it went 9.51 @ 140.65! After a good cool down and a timing
adjustment we were ready to try for a 9.40 run, launching right off idle
the car gave us a nice big unexpected wheelie! The wheelie sure lookes cool
but we know we can go quicker with a little more suspension work to
straighten out the launch and try to keep the front down. We're sure it'll
go into the 9.40's yet and maybe even 30's after everything is worked out.
1970 Buick GSX Engine Rebuild - RKM Performance Center
This 455cid V8 came into the shop under the hood of a 1970 Buick GSX. When
new, the motor was capable of propelling the GSX to 13-second quarter mile
passes in stock trim. Unfortunately, this one was way past its prime. To
get this 455 back in shape, a full rebuld was called for. Technician Jon
Sipple gives us a quick overview of the process.
