383 / 500 Horsepower Stroker

Below is a list of frequently questions and concerns


What application vehicles would this engine work best with ?

This engine will work with a wide range of year, make and models. For instance Early to later model Camaro's, Vettes, Hot Rods & Trucks to name a few. We will match up the necessary components to your vehicles requirements. For Example  some engines will require a different oil pan, flywheel, harmonic balancer and Water Pump.

What about idle quality and will I have enough vacuum to run my accessories ?

This is a pretty common question. We would rate this engine as a happy medium as far as idle quality goes. It has a little bit of a racy sound to it but it's not going to shake you to death! Usual idle is around 900-1000 RPMs. This will depend upon other factors. Vacuum will be fine for running accessories like Air conditioning, Power Steering and Power Brakes.

What other engine will this engine interchange with ?

The 305 and of course another 350 will interchange very easily with this motor. Earlier applications like a 265 or 327 can work with very minor modifications. 4 and 6 cylinder conversions also a possibility. Speak to one of our sales / techs on this.

What octane gas does this engine require ?

 All our engines will run on good quality pump gas. This engines compression is below 10 to 1 so it can run very comfortably within 91 to 94 octane range.

What is the Redline that this engine be taken up to ?

This particular engine we would suggest RPMs be kept to under 5800 RPMs.

What is the Power Range of the engine ?

2000 thru to 5800 RPMs  Making this great a very broad and streetable setup!

Will my stock Transmission work with this engine ?

In most cases the answer to this questions is Yes. A great deal of our customers re-use or freshen up their existing transmission.  For mostly cruising around and / or laying down some rubber once in a while the factory transmission will hold up fine. Those of you who are doing holeshots and abusing the crap out of your car (You know who you are!) you may want to step things up. We may be able to give you some ideas or just talk to a Tranny guy. If your without a transmission and looking for advice on which to choose from. A heavier duty 700R4, TH350 or a modified TH400 Automatic Transmission will do the trick. For Manual  Transmissions there's a lot available like the popular Tremec 5 or 6 speeds with an overdrive gear.

Will I need a higher Stall speed torque Converter to compliment this engine ?

This question applies to Automatic Transmissions only. It's not required, the factory converter will be OK to use. But depending upon the use of the vehicle on the street or the track then maybe one step up on the factory stall speed could improve acceleration off the line. Other factors like the weight, gearing , tire size can come into play too. Speak to a Transmission expert on this. 

Will it be required to change out my Rear End & What Rear end and Gearing is recommended with this engine ?

Two part question. Many of our customers past and present have used their existing gears and have been pleased with the results. But this again comes into play what you want to do with the vehicle. For the most part a rear end gear ratio of 3.55 up towards 4.11 would be ideal. The RPM range that you drive in most will determine what's best for your situation.  Speak with a Rear end expert for some assistance on this matter.

Can I use my existing Exhaust manifolds?  Are Headers required and what diameter should be used ?

Yes you can bolt up your existing exhaust manifolds and in most if not all occasions that will be a direct fit. But as you may know an engine acts like a pump the more efficient the air and fuel is delivered  in and exits out the better and more responsive it will become. The Edelbrock Aluminum Cylinder Heads on this engine have the same factory bolt pattern to work with pretty much any standard Header. A general idea in Header size would fall in place of 1" 5/8 to 1" 3/4.

What size Radiator is recommended ?

Last but not least!  This engine or any other engine we offer needs to run cool to expect long term results out of it. A used / older radiator that has been sitting around is not worth cleaning and reusing . A new 3 or 4 core Radiator is a cheap investment compared to an overheated $5,000.00 engine!  It's worth the investment to spend a couple of hundred bucks to get a new radiator. Pay a little now or pay Later philosophy. There's plenty of good Radiator companies out there
