So I'm doing something similar to what you are doing...with you changing the compression ratio what are the benefits

 

more power. Its a trade off with timing though. Higher comp better torque as well

 

last package to finish the build

 

curious with GMR cams do u need different rockers?

 

No.

Solid lifters.

 

^^This

 

Well, ideally you'd need rockers with 1mm higher mounted ball bearings to compensate the smaller base circle and keep correct valve geometry...
Sadly these do not exist, so solid lifters is 2nd best.

(Maybe you can fit some valve stem caps, but normal caps would need some modding (sides) so they fit inside the rockers...)

 

Edit:double posting

 

The way the valve stems are nested into the roller followers makes it hard to use any sort of lash cap on the valve. I was looking into titanium valves and the main issue there is that you need a different material at the top of the valve as galling is an issue there with titanium. Raising the valve height would still change the valvetrain geometry on its own, so if the goal was to keep the valvetrain geometry the same, you'd have to do different lash adjusters (solid lifters) and taller valves. I've still been looking for other roller followers with different bearing diameters, but, haven't found anything usable. Thankfully, zrated here purchased my GMR cams, so, I don't have to think about it any more.

 

passed the headache to me

 

i think what i still may be doing is using the oem lash adjusters with the gmrs. Even with the head casting and the way the bore is, we may build the bore up and machine it back down to run the oem stuff, so no shims needed

 

I found my own, different solution in the process.

But, being broke, it'll be a while before I can do anything with it.

 

Hey Z rated what are u pushing for horsepower these days ?

 

^^^ a lot

 

figured id bump this


alot in the build has changed for the better ill update soon. She should be running this coming weekend got the ported and polished head back looks sick

 

lookin sexy! how hard was it to do with the motor in?

 

its not hard to do pistons and rods with the block still installed...most people leave the blocks in if they are not sleeving...at least from the builds that i have done

 

it wasnt hard. But me being a tech, i spent alot of time honing the sleeves, cleaning everything and gapping the total seal rings by hand. All tedious stuff. Most that throw pistons in dont hone the block, let alone hone it in car

 

hey T how much money do you think this cost you roughly? i'm trying to budget to do a similar build currently

 

click info is priceless

 

Are you still working on the engine? Lol!

 

whatever happened to this?

 

He had a kid.....

Right Kenny??

 

Only excuse i can see is hot girlfriend. The kid you can always strap in a bouncy buggy out in the garage

 

lol build has change a WHOLE lot since this lol. I really dont frequent the forums too much anymore. But a sleeved big blore block is going in now on top of my turbo setup
