Q

Do you use a reground crank?

A

No. We use only new cranks that are designed for 383 standard 350 mains and standard rod bearing.

Q

Can I have a larger cam?

A

Yes. We explain how a larger cam will affect how the motor will run and act.

Q

Will the larger cam cost more money?

A

No. As long as it is a flat tappet hydraulic cam, your cost is the same.

Q

Will the 425 HP motor pass emission testing?

A

Maybe, but we don't even suggest that it will. We do offer a motor with less horsepower that will come closer to current emission ratings.

Q

Does the 425 HP motor come with forged pistons?

A

No. We use Keith Black hypereutectic pistons but we do offer forged SRP, Lunati or TRW pistons as an upgrade option.

Q

How do we make a 383 stoker? (because Chevy never did)

A

We use a 3.75 stroke crank, 5.7 long rod and a special stroker piston. The 3.75 stroke is what lets the 383 make more torque at a lower RPM.

Q

Do I have to run a large torque converter?

A

No. If you use our standard cam you do not. If you choose a larger cam, then you will. We will make sure your converter matches the cam. This is very important.

Q

Will the 425 HP take any N.O.S.?

A

Yes. 100 - 125 HP as long as we know when we are file fitting the rings. If you want a N.O.S. motor we do build them. Our 495HP 383 on pump gas long block starts at $6100.

Q

Do you use stock rebuilt rods?

A

No. We use only new 5.7 or 6" rods 5140 - 4340 with ARP bolts. If you stop by the shop we will show you a oil pan with a large hole in it that a stock rod came out of.

Q

Does the long block come with dampner and flexplate?

A

Yes. Our 425 HP motors are externally balanced and must have a 400 balancer and flexplate. Balancing is done in-house.

Q

Do you offer a short block version of the 425 HP model?

A

Yes. We will need to know what head you are using so we can be sure your compression ratio will be what you want.

Q

Do you have the motor all built and ready to pickup?

A

No. All of our motors are custom built and 80% are different based on the amount of options we offer (from cam options color, oil pan, and other upgrades).

Q

Can you use my short block to build the 383?

A

No. We do not use any stock cranks, rods or pistons. We will use your block. We will give $125.00 credit if you furnish a good block.

Q

Do you offer any type of a financing plan?

A

No.  We do have some ways to help. We take 50% down with your order and the balance when the motor is complete. Or, we can do it in 4 payments of $1000 each but we will only complete work up to how much money has been prepaid.

Q

Does the price of the motor include freight?

A

No. We ship freight collect. We get the best discount and we pass it on to you. Truck freight cost you from $210. to $245.We do have a pallet/box charge of $50.00. Also we ship all motors on metal skids/motofeet. We charge $45.00 which you can get a credit for when you send it back to us via UPS.

Q

Do you install motors?

A

No. We do not have the facilities here to install motors.

Q

Can you build a 383 stroker from my small journal 327 block?

A

No, because of the main bearing size. We can use the 327 large journal block, but most of them are 2 bolt.

Q

Do you Dyno every engine you build?

A

No, but we do offer this service on complete "Ready to Run" motors. The cost for this service ranges from $500 to $800.

Q

If your 425 HP is $4495.00 How much does it cost for 375 or 400 HP?

A

$4495.00.  The parts cost almost the same, so you do not save money by installing a smaller cam. We do offer a budget $3795.00 motor.

Q

Does StrokerMotor offer a complete 400 long block?

A

Yes and No. We do not offer a stock block 400 because of its lack of availability. We do offer a Dart or World Products upgrade so you can build a 400, 420 or a 434. The block upgrade starts at $1990.00

Q

On StrokerMotor's aftermarket cranks do I have to balance them if I'm only going to use it for street use??

A

Yes. Because the manufacturers do not know what pistons and rod weight you are using, so they leave the crank heavy. We offer in-house balancing.
