With a good tight deck and a nice open chamber like your heads now have, you will have absolutely no problem running 9.5 on premium pump gas. Keep the timing in check. I would say 28-30 degrees total advance. As for the torque specs, I go to 30 ft. lbs on the big main studs, 15 ft lbs on the small perimiter nuts and 23 ft lbs on the head studs.

OK... trying to figure out what spacer I need now... want to end up somewhere between .045 and .040 (sound right?). So far every combination I have for spacers is no good... I go from .035 to like .056... and larger...

Anyone know if I can buy spacers or shims closer to me? (Lou/IN area)... Otherwise I will need to order... looking to pick up a set of .060 and a set of .020... I am pretty sure those will get me what I need with a mix of what I have... I have a .055 that with the .020 might do it (.046) or I think the .060 with my .010 (.009 actually) will get me .040.

wish I could just pick up what I needed local...

thoughts?

OK, I think I have my numbers... I will just need to order the spacer. Note the size of the spacer was what my meter showed... guessing it was 75 and 65 though...

1

2 ( .074 gave .045 deck) (.064 gave .035)

3

4 ( .074 gave .050 deck) (.064 gave .040)


So now before I order (I hope this is the last time). Do I want to run .040 or .045?

78mm forged crank
CB perf. H beams
94mm mahle pistons
This case will be decked in the future so its equal or I will replace it one... but for now I am going to need dif numbers to get what I want.

And to be clear, I quit trying to measure each side of the piston pin and now I only measure into the hole they have on the deck height tool where the screw was.

thoughts?

I posted the same question on onther form and they are telling me I will have detination with that compression with the size cam I have... is that true... or was he saying detination with that cam if I run pump gas and high compression? I need to get past this part... so many people have dif. opinions on this subject... its driving me nuts.

78mm stroke
98mm bore
w110 cam
Head CC 56

.040 = 9.6
.045 = 9.5
.050 = 9.4
.055 = 9.2
.060 = 9.1
.065 = 9.0

Thoughts?

If your concerned about it just set it up at .050 and be done. I just finished an engine pretty much identical to yours and it was 9.4:1 with a cam very similar to a 110. Keep a good tune on it and keep the timing in check,you will be fine. If your still worried add some good octane booster or mix a gallon of race fuel per tank.

thanks guys... I will shoot for .040 and see how it runs... I dont mind getting a tank of race gass and adding a mix if needed... as long as I can get it in under 050 I think I will be fine... but shooting for .040-.045

appreciate the feedback...
Aaron, so you ended up with an .048ish deck to get that compression? Should I just shoot for anything under 50?

Now where do you think I should get the spacers?
#2 ( .074 gave .045 deck) (.064 gave .035) (guessing .070 will be .040)
#4 ( .074 gave .050 deck) (.064 gave .040) (guessing .070 will be .045)

seems like most .060 are closer to .055 or so... I need to go out and mic out my stack of colected spacers agn...

I don't like to build them with anything over .055 total deck,including copper head gaskets if they are used. Personally I would set yours up at .045-.050.

thanks... that will be my goal...

question.
my case is not decked so I am off by like .010 from side to side (1&2 - 3&4) so what if I can get say .045 on 3&4 side but I end up with .047 on the 1&2 side... Is that OK?

I ask because with the goof ball spacers I can find (without getting a custom set) are going to be a tiny bit off... I need .080 and .070 to get .045 on each side (+or-)... but the spacers measure like so:
.060 = .062
.080 = .078
.020 = .020 (so I am told)

I have .055's and .010's, .098, .090, .092 (few more sets...) I plan to use the .060 (or .062) and my .010 with the .080 (or .078) to get the deck... but due to the measurements it will be a tad off.

thanks for your thoughts...

OK guys, I finally got the new spacers...

After I had time to try to set the deck I learned 2 things...
1. my mic I am using is junk
2. this is a pain in my ass

but really... after checking the shim and seeing they were all slightly different in size the closest I can get to an even deck is as follows:

1 and 2 (.088) gives me a .052 DH
3 and 4 (.078) gives me a .049 DH

might be a bit closer but looks like it will fall into the .050 DH range. which still gives me 9.4.1 compression... that should be good for high octane pump gas I think.

I am going to mic the sob agn tomorrow and will do so until I am 10000% sure of the exact numbers... then I think I will call it a day... as long as I end up .050 or less (I know it’s not exact, but I don’t think many are) I will be fine... I will have the case decked over the winter and make sure I can set it to an even tighter deck height after I have some case work done.

you guys think I will be good set up this way? thanks for your thoughts...

Also should my w110 be OK for 9.5 compression range? looking on the site they say 8.5.1 max...

With your heads ported it will run Good and make good TQ and HP to 5500. I would run 1.25 or 1.3 rockers .

thanks for hanging in there for me man... I ended up with an .049 deck... not to bad... I have CYL 3&4 on right now with the head snugged up waiting for the threebond to tack up good before I torque it down... nice to see the heads going back on... wish I could buy you guys all a beer for the help... beed several years since I have torn one of these appart... just want it to turn out well...

Off to get the other side on and call it a night...

It is difficult to get them all exactly the same unless you cut the piston tops. .003" isn't gonna make a bit of difference. Good luck, its gonna be a whole new animal now!

I have a set of solid shafts should I just get the rocker arms for them? if so which ones (brand wise)... Looks like CB Perf. sells the 1.25 rockers... I am looking to see what I can find...

I have an adjustable pushrod one the way and have a set of Chromalloy pushrods that I can cut to length as well.

this is next on my list for the motor.

I see CB Performance has a set of 1.25 rocker arms for 157 (super stock rockers) they also have nicer ones for like 240.00. Also I see Scat and Empi sell a 125.00 version as well.

any thoughts...

I like the wons with lash caps like Scat racing forged or pauters rockers. But i have seen all the otheres work.

Cant you add the lash caps to any set of rocker arms? I am looking for a deal... Dont mind used from a good source. My pushrod tool is on the way... Just need the rockers.

I see the scats and empi and others... but only new sets with lash caps (250ish)...

Example:
1.25 High Ratio Rocker arms Price: $125
Empi high lift ratio 1.25 rocker arms with bushing.made from forged chromoly, strongest rocker arms available... $125.00 shipped

but I bet I should be able to locate some used ones for not much more that are better?

You should be looking for the rockers that have the adjuster on the pushrod end of the rocker arm. The stock style 1.25's work fine but they are a pain in the ass and take some work to get the geometry right with swivel feet in them.

I see these out there:
New Scat rocker sets, 1.25 Price: $239.99

I like the CB performance product better I think but its a 1.3... I have read some things that tell me that 1.3 may be to hard on the valves...

Are these the rockers you guys were talking about?

I took a chance.. a set of the Scat 1.25 rockers from samba... I hope it works out ok...

scat 1.25 ratio rockers Price: 120

Look like the pro street rockers to me... they sell for like 250.00

I think My next post will be in another thread... this one is getting long... will start something off for rocker geomitry...

thanks guys...

Thats the wons you wont. Early scats 1.25 will do 1.25 to 1.3 .You will have aroud .490 to .509 lift. You have dual spring right.

yup, dual springs...

Nice score! They look brand new. Did you get the lash caps as well?
