Big Block Chevy Gen 5 & 6 Thermostatically Controlled Engine Block Adapter
Thermostatically Controlled Engine Block Adapter Gen 5/6 BBC
Maintaining proper engine oil temperature has become critical to the success or failure of today’s performance marine engines. Prolonged use of marine engines in conditions where oil cannot reach its optimum working temperatures will result in sludge formation and crankcase dilution which leads to excessive wear especially in the cylinder bores and bearing surfaces. A thermostat assembly combats this by permitting 90% of the engines oil to bypass the cooler during warm up. The balance of the oil flow is allowed to fl ow through the cooler maintaining constant pressure and preventing air pockets while eliminating cold oil shock. This reduces scuffing and premature wear and inhibits engine blow-by. As engine oil temperature reaches its optimum operating temperature moisture and impurities that often cause a milky condition are eliminated.
Until now oil temp was controlled either by some guess of components or by the professional engine builders through the use of some sort of external engine oil thermostat. While these external oil filter/ thermostats were very effective they were also very large and very bulk . Making them hard to mount and creating a maze of plumbing. The problem was the only available parts up until now couldn’t move the necessary oil fl ow to be mounted anywhere. else. But thanks to Hardin marine and their engineering staff they took to solving this decade long nuisance. Hardin Marine has developed this new thermostatically controlled engine block mounted product. With this unit all oil temperature is now controlled through a integral 212 degree oil thermostat. The large 3/4NPT oil inlets/outlets assure the maximum amount of oil can be fl owed through the unit. So no more maze of external plumbing, no more big bulky external mounted components just the standard (2) lines to the filter and the standard (2) lines to your cooler. Sometimes evolution comes in the form of the simplest of things but this is one that has been deeply sought after. Overall Height: 4-3/4"

Xtreme Marine™ Seal Cylinder Head Gasket - Big Block Chevy Gen 4 454, 4.370 Bore- Sold Each
The most demanding sealing job of any marine engine is the sealing of the cylinder head to the engine block, and for that reason we have incorporated the finest gasket core and combustion armors along with 300 series stainless for corrosion protection into our product line. This non-retorque style head gasket is the perfect choice for today's high performance recreational power boater.
- Excellent corrosion protection
- Eliminate hot spots
- No retorque required
With over 40 years of marine engine manufacturing experience under our belts, building high performance and original equipment engines has provided us the insight needed to develop what today is considered to be the marine industries finest gaskets available today. Dependability and durability in both fresh water and harsh salt water environments. Marine engines operate in conditions far more severe than their automotive counterparts from cool water rushing in against scalding hot cylinder walls to exhaust temperatures exceeding 2,000 degrees Fahrenheit. Rest assured each Hardin Marine seal and Xtreme Marine Seal gasket was designed for its specific purpose. While marine seal gaskets are the perfect choice for an OEM application the Xtreme Seal gaskets are strong enough to be chosen by the world's leading offshore engine manufacturers.

Block Chevy Crankshafts
The new line of Voodoo
Crankshafts are engineered from 4340 forged non-twist steel that is
known for its durability and strength in high heat applications. To
add even further durability and consistency all Voodoo Cranks are
nitride heat treated with micro polished journals . Furthermore by
inserting lightning holes into the hod journals, the crankshaft inertia becomes lighter for faster rotation.

Voodoo Series Big Block Chevy H-Beam Connecting Rods
Voodoo Connection Rods are H-beam rods created from 4340 forgings. Voodoo Rods are strength and quality tested through stress relieving, shot peening, and magnafluxing. To remove stresses from the metals, stress relieving is used. By heating the metals to a certain temperature and then allows them to cool in still air; this helps with the removal of remaining stresses from the metal. Shot peening is a process by which small metallic particles are used to impact the surface of the material being used in a part's construction and creates compressive residual stresses on that surface, which can then longer withstand cracking and breaking, thereby increasing the lifespan of the part. Furthermore, magnafluxing is running a magnetic particle filled fluid over and through metal parts. The magnetic particles attach to any flaws or fissures in the material and magnifies them so that it can be identified and removed from use if necessary.
