STROKER...

[SSCamaro2010]

Im looking to make my motor a complete forged stroker. i have a cam, lifter, rods and full exhaust. i know going to a 416 is pretty safe. How much on average to have a shop AKA lingenfelter build my motor for me, and what kinds of gains have you guys seen with a NA forged stroker LS3?

I went through this last year when I did my engine. The cost will depend on several factors. Are you just looking to have them do the short block? Or are you looking to have the long block? Are they going to add the accessories or are you?

What are the benefits of a short block vs long block. As far as accesories, i plan on droping off my car having them do 100% of the work and going back to pick the car up once its completed

Ive seen 416 short blocks go for less than $5000.

Forged 416's are usually for F.I. If you plan on staying N/A I would build something that is 427+ci. A crate motor works for what you want.

LOL Says who?

I have plans on a 416-418 when its time and I will be N/A.

What are your cam specs?

Reason I ask is because if the cam is a grind optimized to work with the stock stroke, you're going to need a cam with more duration usually to have the same operating range.

If you dont, You are essentially wasting the extra "effective stroke" you would have available to you with the proper cam as well.

The shelf cam for the 376 used in a 416 is going to have a lower torque and power peak than the 376 had, and depending on if your stroker assembly piston has yields compression or not, you may also find that the cam with the smaller duration is going to have more cylinder pressure than you may want. In some cases this can limit the total spark advance you can use, and/or raise the octane requirement making fuel more expensive.


Just saying.

Say what???

This is so dead wrong. Stroke is pure mechanic advantage (longer lever) and the best thing you can do to make torque and power. There is no way EVER that the same engine with more stroke does not lose power. In fact it makes nearly lineal power gains (20% more stroke = 20% more torque).

I've also got the stats to prove it. My race car went from a 302, to a 350 to a 383. Same bore, heads, cam, everything but crank and rods. Kept stroking it out.

302 ran 11.80, 350 ran 11.10 and the 383 ran 10.60.

Geez man, where do people get this mis-information?

Depends on how you get the bore size. Either buy a ls7 block or a sleeved block. How much power difference are you going to get out of 10 cubic inches vs how much it costs to get those 10. I too believe in displacement but its not like going from a 383 to a 408.

That why I suggested he go 427 c.i plus. It's about 1.5 HP per cubic inch. So 376 to a 427 is 17 Hp over 376 to 416. Building a beast of a N/A motor is not a cheap proposition. Slap a 440 in the thing and be done.
