I am thinking of building a 383 with a custome Hyd roller cam probably in the .640 lift and 250 duration at .050 range. My machinist wants to go solid roller.
I have already the non-adjustable yella terras that I used on a Trex. I know I havbe to buy adjustable rockers, but My question is is it worth it to go solid roller. How much gains would I see. Just trying to find out if spending more money is worth it.

 

The solid roller is there for valvetrain control and stability, all depends on how hight you plan to spin the motor. With a solid setup you are going to need a few more things, solid Lifters, restricted pushrods, taller valve covers, and the ability to adjust and set your own lash just to name a few.

In a properly matched setup a hyraulic lifter can handle that cam without a problem. But Mismatched components like heavy valves, heavy rockers and stiff springs you will start killing lifters.

 

If i stay hyd roller, What lifters should I use. I Have only ever used the stock and those always held good for me but now I don't know what lifters to get if any.

 

Crane says on their website, and ive seen on paper a solid 10-15hp gain in the upper RPM range. Is this worth the time/money invested? Thats up to you...

 

depending on your budget you could get the Morrel Hydraulics, GM caddy racing lifters, or Stock replacements. In a new motor i would spend the extra little bit of money for a new set of lifters even if they are stock replacements.

 

Thanks guys

 

i dont see way you would use solid lifters unless it is a race motor or you plan on spining over 7500rpms

 

Up to 7500 but no more.

 

since going solid roller i think any motor i do from here on out will be solid roller if its going to be 50/50 street/race.
you can run bigger cams, make more power rev higher etc etc.
im liking the solid roller alot.
and they are not as much work as most think. i put my rockers on 1st of the year, have a good 50 passes and have not touched them. i pulled the covers off once to check them, but thats it

all ive done to my car this year is change the oil

 

Well if I sell enough parts ill go solid roller. My machinist is really recommending it.

 

If you need anything, rockers, pushrods, or a custom cam give us a call, we would be more than happy to help you with your build.

 

With a 383 4" stroke, you are better off keeping the revs to a max of 6800ish since the piston speed is higher due to the longer stroke. Better off using a cam that makes its power lower so that you can use the full potential of the extra torque a stroker will give you. Hydraulic lifters would be a better choice for that kind of motor.

 

I dont agree.... 402's/408/418/427 motors are all revving past 6800 without a problem.

The stock short rod ls7 spins 7k from the factory with a heavy *** pin.

 

I bought callies crank and rods if it makes a difference. We are planning on reving to at least 7200, maybe 7500. Depends on how cam works out.

 

My solid Roller 410 is limited to around 8000rpm by the wetsump oiling system but can be revved to 9k without a problem if choose to go drysump.

 

i do as well

 

Wish I could go solid roller but I don't have money to buys adjustable rockers and all needed for it.

 

with the right components a hydraulic will go 7500 no problem
