The Automotive Machine & Performance 2006 Entry to the
Popular Hot Rodding Magazine Engine Masters Challenge
Specifications - list of parts and machine work - Costs to Build
This is positively the baddest 430 Buick engine on the planet
and it will run on pump gas
We made 87 dyno pulls on the 434
It was disassembled and found that it had performed flawlessly
These pictures are of the re-assembly

653 Horsepower

windage tray and scrapers
Port matched to oval heads
T/A Stage 2 Street Eliminator heads were modified to oval port which reduced the
intake volume by 10 cc's.
The 434 cu in engine benefited by greater velocity and still flowed over 345 CFM
T/A 1.65 Shaft rocker arms
A Faith Air intake collector was utilized to maximize fuel
atomization. This is the most sophisticated carburetor
spacer on the market, it made almost 10 HP in the entire
range over the best transitional spacer.
The Scavenger Oil system uses factory style pump to redirect the oil from
the pan to the engine without all the harsh turns and restrictions in the
block. Note that the oil filter housing would normally be mounted on the
fender panel
This engine is complete from carb to pan
SFI approved damper to flexplate
Every part, down the last bolt is
brand new in and on this engine
except for the extensively
machined block and de-stroked
crankshaft. T/A Performance parts
were used almost exclusively.
The bore and stroke of this engine was determined to be
the best way to maximize power and stay within the limits of
the rules for the 2006 Engine Masters Challenge
competition
Probably the only oval port T/A SE heads in existence
