Pontiac Stroker Kits Eagle Pontiac 400 and 455 Stroker Kits
Pontiac 400 and 455 engines make good torque and horsepower, even with a
stock stroke crankshaft, but an Eagle Pontiac stroker engine kit will improve the
performance of these engines even more. If you are rebuilding a 455 Pontiac and want a
stronger rotating assembly, but do not want to go to a stroker crank, we have a stock
stroke 455 kit for you in addition to a 455 stroker kit. We offer a Pontiac 400 stroker
kit, a 455 Pontiac stock stroke kit and a Pontiac 455 stroker kit. We also offer
custom piston options on these basic stroker kits, so if you want something like a
different compression ratio piston, or different bore size piston, or both with your kit,
we will be happy to take care of that for you. If you want a piston set with different
specifications in your stroker engine kit please
and let us know what you are looking for and we will be happy to get a quote back to you,
for your exact application.
We offer the Pontiac 400 stroker kit, 455 stock stroke and 455 Pontiac stroker
kit balanced, or un-balanced if you prefer to have your local machine shop do the balance
work for you. Prices for these kits do not include shipping or balancing. If you would
like for us to balance your kit before shipping, please
and we will be happy to give you a price quote for the balancing work.
Engine Kit Contents Description
Our Eagle Pontiac stroker engine kits offer a great balance of strength, performance,
dependability and affordability. Each of these kits includes a Eagle cast steel
crankshaft, ESP 4340 H beam connecting rods, SRP forged flat top pistons with valve
reliefs, moly file fit piston rings and Clevite 77 bearings. The Pontiac stroker
kit comes with a crankshaft that is designed to be used as internal balance. The
stock stroke 455 Pontiac kit is also intended to be used as an internal balance assembly.
