Great motor, great value

December 06, 2015
After searching the Web and comparing what is needed to get this motor running, it's the best bang for the buck, plus it has a lot of bang! Since it is dyno tested with common headers and an edelbrock 750 carb, you know those results are attainable. Shipping was super fast! I've got my 383 in my ugly 69 C10 and it just sounds angry. I love it.
Pros:
  • Complete Add Carb Pump
  • Dyno Tested
Yes, I recommend this product.

Great power, nice looks

September 05, 2014
Bought this and installed an edelbrock air gap intake and immediately noticed large torque gains. This engine is throaty and blunt, perfect for my 86 k10. Moves the large tires and wheels with ease. Recommend a rebuilt 700r4, needs upgraded internals to handle the power though.
Yes, I recommend this product.

Yes a 383 cubic inch small block Chevy is commonly referred to as a stroker. It is a 350 engine which has a longer stroke crankshaft installed (3.75" stroke as opposed to the stock 3.48" stroke). This engine is bored .040" over as well.

Answers

EricM
We apologize but currently do not have a universal full length header that will fit in the year of your Corvette. A 670 Holley Avenger or 650 Edelbrock AVS is suggested but if you have a 650 Holley already it would be sufficient as long as jetted properly. The HEI distributor that comes with the engine has the tach terminal in the cap for hook up to an electronic tach. If you have an older Corvette with mechanical tach drive we apologize but do not have a distributor to fit your needs.

Yes this will bolt right into your 1986 GMC. It will bolt up to the original transmission but you should strongly consider having the transmission upgraded to handle the power of this engine. Sorry we do not offer any 4x4 transmissions.

Standard small block Chevy headers fit this engine. Ideally a 1 5/8" or 1 3/4" primary tube header would be used.

Answers

EricM
This engine does have a provision for a mechanical fuel pump. If you use an electric fuel pump you will simply need a block off plate 91011515 or 91011521. If you plan to install a mechanical fuel pump you will need a pushrod such as 1011348701 as well as a fuel pump plate 5501514. A stock SBC fuel pump pushrod and plate can be used as well.
