Iv'e had a slight change in mind about the way i want to do my motor i think i want a stroker,do anybody have a stroker motor i would like some info like who got the best prices and how is the performance

 

JLP runs a stroker motor.

 

If your truck is a daily driver then I personally wouldn't stroke the motor. I was going to do the same thing but after I researched it I realized I'd probably be replacing pistons twice a year the way that I drive mine. In case you didn't know the rods are already quit long in the motor. If you added longer rods you would be creating a lot of stress on the sides of the pistons. I decided to go with a built long block w/stage II cams insteads. Do a search if you want more info on it. It has been brought up more than once.

 

Psssst... you already are!

the 5.4 is a stroked 4.6

 

Psssst, no it's not. A 5.4 has a taller deck heighth than a 4.6.

 

yes we do run a stroker. and sell them. we have run our stroker motor ALL season running numerous 9's!..and never once replaced the pistons or anything as far as that goes..we have 1 customer who has run there's on the street now for over a year with no issues..JL

 

Johnny, are your stroker cranks made special for you? Are we able to use say a 4.6L crank to make a stroker engine?

I ask this cuz I know that in some chevy engines you can use a crank from a diffrent motor to make a stroker?

 

yes suavy there made special....JL

 

Ive got a buddy that has one of the strokers. He said it wasn't worth the trouble and he has been dissatisfied (i think hw told me his was the second crank made). If you want to talk to him about it his screen name is "rusty". But as the saying goes "different strokes for different folks". Sometning else you might want to consider is the Sean Hyland Motorsports big bore block. I priced the both of them and at the time the bigbore route was cheaper and you didn't have the rod angle to deal with.

For a competitive drag racer like Johnny, this might make sense.

But for anyone else, why fool around with real displacement when effective displacement is a pulley change away? On a blown motor, it just makes more sense to bulletproof the engine and crank up the boost.

Witness the sick amounts of power produced by 1.5 liter F1 turbos or the 2 liter Toyota and Nissan GTP engines. Once they figured out how to keep the engines together, the sky was the limit -- some have estimated nearly 2,000 HP in qualifying trim.

p.s. -- they were running as much as 5 bars boost (73 PSIG)!

 

NEVER THOUGHT IT WOULD BE THIS HARD MAKING A DECISION THE ONLY BAD PART IS I'VE ALREADY GOT SOME NEW PISTONS AND RODS MANLEY ALSO STAGE II HEADS I QUESS IT DOESN'T MAKE SINCE TO CHANGE NOW SINCE I ALREADY HAVE PARTS THANKS FOR THE HELP!!!!!!!

 

I agree with Tim on this subject.

Unless your looking for every little ft lb of torque and could care less about the costs? A more efficient blower (more and cooler boost) is a much better bang for the buck.

Dude.... Kill the Caps Lock

 

And pneumatic valves so they can turn them to ridiculous rev limits...18,000 rpm. Small motors tend to make big power if you can spin them fast enough. I've got a dyno chart from when Paul Tracy's Indy car was dynoed...like 300 ft.-lbs. but 800 hp at 15,000 rpm! HP is just a factor of torque x rpm squared divided by 5252...make enough torque at a high enough rpm range and instant HP.

 

Speed 12: E-mail me if you want to get rid on the Manley rods and pistons.

Oh; a comment to dirtchicken: I'm pretty sure that longer rods actually decrease the side loading of the pistons, which is why (for example) on the 383 Chevy small blocks, a popular change is running the 6.0 long rod rather than the kinda short 5.7 the factory used with the 3.75 stroke crank in the 400 small block. The only problem in going to longer rods is avoiding the compression height problem where you get the pin up into the oil ring area. Other than that, as you might expect, longer is usually better!
