Finally my 383 build

Question about adjusting the valves on roller assemblies. I know I want 0 lash and usually the way I have done that on flat tappet is to tighten down the rockers until the push rods are hard to spin. With these roller hydraulic lifters there is quite a bit downward spring movent in the lifters. Do I want to take that space up or does that fill up with oil and get taken out when the engine is running?

*edit* Nevermid read its same as flat tappet.

Tried to get the motor in today damn cherry picker doesn't have enough reach. So now I gotta go to the steel shop and see if I can get a longer beam. Need about 6 inches more reach. It's always gotta be something!! Just once I wish things would work out without being a pain in the @ss!!!!!

It's a cherry picker. The hydraulic ram hits the front bumper and I don't have enough reach to slide it back to mate up with the transmission. I drilled some new holes in th steel beam to make it slide out some more. I picked up about 5-6 inches. I'm gonna try again tomorrow. Wish me luck!
 
Drilling new holes in the beam to extend the reach worked perfectly.

New motor is in and started it up and it revs great just have some more fine tuning to do.
 
So drove the thing to the gas station and it's a beast!!! Wicked fast should have no problem towing the boat now. Breaks my 35" tires loose with ease :) I still have some fine tuning to do. I'll have to see if I can post a video once all the bugs are worked out.
 
Sweet. You've.been working hard on that thing.

I may have missed it but it had a stock 350 in it before?

And I was gonna ask, did you do any computer tuning or is that the fine tuning your talking about

Ya it just had a stock 210hp turd with a mild cam before. I rebuilt that motor and sold it to a friend.

Brian at tbichips.com is doing the tuning. It runs like a beast right now and I am doing some data logging and sending him the results to fine tune it some more.

I've got the 54mm TBI on there and the thing runs awesome. TONS of low end torque. I was never able to spin those 35's before unless I power braked it which isn't impressive. Now I can just smash the skinny pedal and it will spin those tires through 2nd gear.

nsxxtreme, What are your cam specs? I'm working on a similar project and looking for towing power as well. Sounds like you got just what you wanted with your combination.

I have the Lunati 60121 cam you can look up the specs.

*edit*
Actually I'll need to go back and double check I see earlier I posted 60120. I'll let you know as soon as I find it.
With the whirlwind of parts comming in the mail and all the money flying out the door I might be one diget off :)

I'm extremely satisfied with how this engine turned out. My Range Rover is 330hp stock and my butt dyno tells me this is way more. I went by this article http://www.carcraft.com/techarticles/ccrp_0808_383_stroker_small_block_chevy/viewall.html but changed a few things. After looking into the cost to set up a set of vortec heads for high lift I just went with the edelbrocks. I don't know how machine shops stay in buisness when they aren't competitive with new parts. I also got a lot of help from Brian at TBI chips. Really good guy who knows what works and what doesn't.

Next project will be to get a nice bumper and a winch on the thing.

so currently you are running that motor with a bigger throttle body and stock puter?

I dont know what a stock puter is.
But I think you meant ECM? Yes I have a larger TBI and no I dont have the stock tune.
 
Yes, puter = computer. Sorry for the redneck slang...

So you got it chipped for the cam and motor specs to get it up and running, now you are going to data log and/or dyno to final tweek it? Just trying to get the process right...

Basically yes. Tune it the best we can without the dyno then check it on the dyno and tweak some more.

I know exactly what you mean with the cost of setting up used vortec heads. My machine shop actually recommended buying new instead of dumping $$ into a used set - I went with a pair of cast iron vortecs from RHS.

The cam you listed looks correct - it would be a good match for your heads and intake. I think I'm going just a bit milder than you - staying with a 212 / 218 duration.

Sweet engine build - I hope I'm as satisfied with mine!

So the cam is the Lunati 60120LK not the 60121 I was off 1 diget. It came with the lunati roller lifters.

Voodoo Camshaft; Hyd. Roller; RPM 1600-5600; Adv. Dur. 262 Int./270 Exh.; Valve Lift .507 Int./.515 Exh.; Lobe Angle 112 Deg.;
 
Just an update:
Still doing some minor tuning changes. Thing runs increadibly well with TONS of low end torque. I will need new 35" tires very soon LOL. Even took the thing through DEQ and it passed with flying colors.

Had one minor issue. While tuning I have been sticking premium in it and then planned to back the timing off later so I can run regular. Well went to the gas station and told the kid premium and he stuck regular in it even after repeating premium back to me. Talk about a short attention span from the door to the pump you forget what gas to stick in it!!! So now I have to fill out some dumb insurance forms and have them pump the gas out.
 
This was a good read . . . hoping to build one someday soon. Thanks.

Do you have any pics of what this 383 went into? Or it burning those 35's?
