LT1 Recommendations
We recommend using the following with our stroker LT1 engines, you can find all of these parts in our
LT1 Parts Dept
-30lb injectors with any of our 383ci LT1 engines and 42lb injectors for our 396/550hp LT1
-Golen Ported LT1 Intake that is bored for a 58mm throttle, runners ported and decked. We use this intake with all of our 383ci engines as well as our 396/550hp LT1 engine.
-58mm throttle body
-Adjustable fuel pressure regulator
-Stock GM MAF will work fine for engines up to 500hp. If you have a B-body car it is best to upgrade to a F-body MAF that is 3.5" for better flow, if you do this, make sure that you have your computer programmed properly to match the larger MAF.
-Performance cold air intake and filter unit.
-Custom computer tuning by PCM For Less, Bryan Herter for 94-97 LT1 engines and Alvin Anderson for 92-93 LT1 engines. You can reach them through their website at www.pcmforless.com
-Use only a vented Optispark unit. If you have an early 92-94 LT1 engine with the non-vented Opti you will need to buy the vented unit to work with our engine part #GM-1104032 and the wiring harness connector GM-12130319.
-MSD Super Conductor spark plug wire, these work great!!
-Stock GM Coil will work fine and MSD also sells a upgraded version.
-Use only AC Delco if you are going to replace O2 sensors.
-Aftermarket long tube headers such as Hooker Super Comp 1 3/4 primary to 3" collector for Corvette and Camaro. You can get these through Summit Racing or Jegs. If you buy the long tube headers you will need to get O2 extension harnesses in order to plug in your stock O2 sensors. We stock these for $25 a side. If you have an Impala you can get Clear Image Quad headers that will make good power. You can reach Dan Ferraro through his website at:

-Aftermarket exhaust with high flow muffler and Random Tech high flow cats if you have to use cats.
-Aftermarket stall converter for auto trans applications, 2800-3000rpm for most engines.
-Aftermarket clutch for standard transmissions
-3:73 rear end gears work best with these engines on the street.
-Internally balanced flex plate or flywheel to match crank balancing.
-Crank hub that has the proper key slot for the aftermarket crankshafts we use. We sell this crank hub in our LT1 parts Dept for $100.
-Autolite 104 spark plugs for naturally aspirated enginesand Autolite 103 for super charged engines.
-Joe Gibbs Break In Oil for the first 700 miles and then you can use Joe Gibbs Hot Rod Oil from there on in. Both of these oils have high level of Zinc which is really good for high performance engines.
-Wix or AC oil filters (Do not use Fram, they have a collapsing problem)
-If you are road racing or auto cross racing we recommend a Canton 6 quart road race style pan to avoid oil starving when cornering at high speeds. We also recommend a Canton Aucusump system to keep constant oil pressure in road racing applications.
