Buick Performance Parts

ZDDPlus

It's a well-know fact that older engines especially flat tappet performance engines, require an oil additive know as ZDDP ( Zinc Dialkyl-Dithio-Phosphate ).  This additive has been the most effective extreme pressure additive found in quality motor oils for almost 70 years.

Buick 3.25" Viton ® Rear Main Seal

These Tin Indian Performance Gasket & Seal Buick rear main seals are specifically designed to improve sealing and reduce crank drag in your Buick engine.  These Buick rear main seals fit 400, 430, and 455 Buick blocks.  The rear main seals are made of Viton  ® and are far superior to the factory rope seal.  They are the single most reliable way to control oil in a Buick engine.  

These Teflon carb gaskets help to insulate the carb from the intake are are completely re-usable.  Good for those who take the carb off frequently.  They are also good for use in dnyo rooms!    These Holley carb  gaskets are made of 1/16" material (both paper and Teflon)  

Buick Crank Mandrel Drive System

Our Buick Crank mandrel drives are custom CNC machined out of 6061 aluminum.  The mandrel includes the following features: 

Mandrel bolts directly to harmonic balancer -  You use your stock crank bolt to bolt your harmonic balancer to your crank.  You no longer need to use mandrel systems that use 5 to 6 inch balancer bolts.  Your balancer is now reliably retained by a separate bolt!  Some harmonic balancer manufactures will not warrantee their balancers if you use such a crank mandrel system. 

Works with ALL Buick harmonic balancers with standard Buick 6 bolt patterns!   

FULLY ADJUSTIBLE!!  4 different locating spacers help with belt alignment.  We can also custom machine spacers for you based on your spacing requirements. - Call for details

The standard Buick crank mandrel drive system comes with the mandrel, 1 -  3 inch deep grove pulley, 4 alignment spacers, snout cap and bolt.  Optional items include 4 inch pulleys , gilmer pulleys, and additional spacer kits are also available separately.  See below....

We can also custom machine one of our mandrels to fit inside a March crank pulley as well.  Call for pricing and details!

Individual Evacuation Kit Items

Engine Vacuum Baffle with -12 AN Fitting
The vacuum baffle is designed to reduce the amount of oil scavenged from the crankcase by the vacuum pump. The vacuum baffle is shielded on four sides and open on only one side. This Baffle is not a cure-all for engines that leak or have excessive blow-bye. Improper location of the pickup, poor oil drain back in heads, or an engine with excessive blow by or an engine that is not properly "sealed" can still pull excessive oil.   

Vacuum Pump Intake / Exhaust Oil Separator Tank with -12AN Fittings

Moroso 3 -Vane Vacuum Pump Aluminum, Black Anodized - pulley INCLUDED!

These vacuum pumps are manufactured from billet aluminum and feature a precision-machined shaft, rotor, and bearings that will withstand the rigors of racing. They work by producing high crankcase vacuum, which increases power by improving ring seal, preventing blow by, and detonation.  The pump also allows for the use of lower-tension piston rings for less friction. These positive pumps are much more consistent and effective than header-mounted evacuation systems.  This pump uses -12 AN fittings.  Pump mounting bracket is not included.  Use part # TIP-002.

Moroso 4 -Vane Vacuum Pump Aluminum, Black Anodized - pulley INCLUDED!

Pump mounting bracket is not included.

Moroso 4 -Vane Enhanced Design Vacuum Pump Aluminum, Black Anodized - pulley INCLUDED!

This pump comes with all of the hardware pictured above and allows for the most flexibility for adjustment when used with our Tin Indian Performance Crank Mandrel.  Adjustment swing for the belt tension is a bit small at 1.7 inches.  You just need to be fairly close with your initial belt length.

Aerospace Vacuum Pump

These vacuum pumps are manufactured from billet aluminum and feature a precision-machined shaft, rotor, and bearings that will withstand the rigors of racing. They work by producing high crankcase vacuum, which increases power by improving ring seal, preventing blow by, and detonation.  The pump also allows for the use of lower-tension piston rings for less friction. These positive pumps are much more consistent and effective than header-mounted evacuation systems.  This pump uses -12 AN fittings.  This pump has a custom made Buick bracket included and the shaft provides 6 different mounting locations for the pump pulley.

Adjustable valve cover relief valve

This relief valve has an o-ring located at the bottom and a jam nut included for you to attach to your valve cover.   The spring loaded valve allows you to control the amount of vacuum you create by simply tightening or loosening the valve.

Gilmer pulleys 

We carry both 18 and 20 tooth Gilmer pulleys for our mandrel system.  Please specify tooth count when ordering.

Breather tank

This panel mounted breather/separator can be used with dry or wet sump tanks.  It features a filtered breather from K&N Filters, a drain valve and a - 12 AN fitting.

Mandrel Spacer Kit 

This is the mandrel spacer kit used on our Tin Indian Performance Ford Crank Mandrel.  The kit includes 4 spacers.  2 are .375 wide and the other 2 are .755 wide. 

If you need custom spacers call us!  We can make any size you need.

Frequently asked questions: 

Q:        Why don’t you guys sell a cheaper system with a Ford style smog pump?

A:         You get what you pay for!  The Ford style pumps don’t pull near the vacuum nor do they last as long as the Aeorspace or Moroso units.  

Q:        How fast should I spin the vacuum pump?

A:        Optimum speed is approximately 50% of the engine speed. (2 : 1 ratio).  For applications below 8,000 RPM we recommend running the pump at 66 % ( 1.6 : 1 ratio).  Using the 3 inch pulley provided with the standard Tin Indian Performance Crank Mandrel System will drive a vacuum pump with a 5 inch pulley at 60%.  The 4 inch mandrel pulley would drive the pump at 80%.

Q:        Where should I plum the vacuum pump?

A:         We recommend attaching the pump to the front of the valve cover via a threaded bung.  Our bung baffel helps with pulling excessive oil out as well.  This should provide you with the best vacuum and best lubrication of your pump.  The outlet of the pump should be attached to a catch can that can be periodically drained.  Never attach you vacuum pump outlet to your dry sump tank or to an exhaust collector. 

Q:        How much vacuum do I need?

A:        Most engine builders concur that maximum power gains are noticed in the 13” to 16” on a wet sump application.  Street applications should be less and we normally recommend that you drive the pump a bit slower.
