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
e-mail us
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
kits balanced, or un- balanced if you prefer to have your local machine shop do the balance
work for you.
Eagle Pontiac Engine Kit Contents
Our Eagle Pontiac stroker engine kits offer a great balance of strength, performance,
dependability and affordability. Each of these kits includes a Eagle steel
crankshaft, ESP 4340 H beam connecting rods, forged flat top pistons with valve
reliefs, plasma moly file fit piston rings and Clevite 77 main and rod 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.
