A.R.I. Racing Engines

Pro-Builder® GM 2.8-to-3.4 Stroker ShortBlock Engine

You may have seen our 2.8L to 3.1L GM Stroker Conversion Engine Kit off of our website, on eBay, or on Yahoo!, and now we would like to present you with our 2.8L to 3.4L Short Block Stroker Engine!

A.R.I.’s Pro-Builder® 2.8L to 3.4L GM Stroker is a great upgrade for GM 2.8L-powered vehicles, especially if you have considered purchasing another stock 2.8L for your vehicle and have thought, "A little MORE POWER & TORQUE from this engine would be Great!"  Well, here you have it...

Applicable Vehicles:

  • Any GM Vehicle that originally came with a 2.8L Engine.
  • Includes Pontiac Fieros, Chevy or GMC S10, S15 Pickup Trucks, RWD or 4WD Blazer & Jimmy, Chevy or GM Passenger Vehicles, Jeeps that have GM's 2.8L engine.

Performance Benefits:

  • Improves torque and horsepower.
  • Requires no modification to engine bay or motor mounts because you use the same type of 2.8L block that is in your vehicle now.
  • You get the SAME DISPLACEMENT as a 3.4L Engine, while maintaining the SAME SIZE AND WEIGHT as a 2.8L engine!
  • You can use your stock 2.8 heads, fuel delivery system, etc. and Everything Works Great!
  • Cost is not much more than rebuilding a stock 2.8, so Why Not?
  • Various Performance Camshafts and other Accessories are available to give you even More Torque and Horsepower.  E-mail dwa007@engine-parts.com for more information!

Answers to Common Questions:

  • What is the increase in horsepower and torque?  It is a noticeable increase in power over the stock 2.8L engine.  We have not dyno-tested one of these engines on the dynometer, but with the right camshaft and fuel delivery system, we have had customers get 180+ HP out of one of these engine (which, like I said above, is noticeable over the 115-140 HP of a stock 2.8L engine for just a little more cost). 
  • What are my cam options?  Pro-Builder® Stock, Phase 1, Phase 2, & Phase 3 cam kits are available with this engine.

  • Can this Engine be used with N.O.S. to power my Drag Car?  This is up to you, but it ruins the warranty:)
  • Are other Performance Parts Available?  Yes, Including Cam Kits, Heads, Gaskets, Rocker Arms, etc.  We have quite a bit for these engines.  Visit our pricing page to get prices and ordering info.
  • What does this kit do to fuel mileage and driveability?  Our customers tell us that the engines run great, are reliable, and that their fuel mileage is very close, if any different at all, to their engine before installing this engine kit.

Another Power Increase from A.R.I.


Here it is:

GM V6 2.8 -to- 3.4 Short Block Engine

2.8 - to - 3.4 GM V6 Short Block Engine

  • Thermally Cleaned and Steel-a-brated Block
  • Pro-Builder® Crankshaft
  • Pro-Builder® Connecting Rods
  • Pro-Builder® Pistons
  • Hastings® Rings
  • AE Clevite® Cam Bearings
  • AE Clevite® Rod Bearings
  • AE Clevite® Main Bearings
  • Brass Freeze Plugs

We do not sell this engine as a kit.  It is only available as a shortblock or longblock because each block must be sonic tested prior to building to ensure proper cylinder wall thickness for strength and cooling.  We do all necessary machine work to the block, crankshaft, and connecting rods prior to assembly in our own In-House Machine shop in Missouri.  Then, each engine is assembled by one of our qualified Engine Assembly Crew.  All this leads up to an engine you can trust and get a noticeable power increase out of over the stock 2.8L engine.
