Think the compression will be somewhere 8.8 depending on final measurement. Here are pictures of the bearing. When I measured the journals I did check them 90 degrees apart. I did not find any R on the crank and the block got no maltese cross. Below are some pictures on what markings and...

Thank you nm9stheham for taking your time to answer and explaining. Also appreciate all you others for taking the time. My guess is that the bearing fitted from factory is a .002" bearings and that's why the factory bearings are marked "AT-20". When I measured the rod journal again today it...

The OEM bearing are marked AT-20 so that's why I thought something was 20 something of. I made a mistake when measuring my rod at first so that's why I assumed it was the rods because the mistake measurments was 20 thou off on the rods. I'm not sure any more what to think but I will measure...

nm9stheham I will measure the rods tommorow at the break. But I think I may found the problem now when I was calculating the measurements taken on the rod big end from mm to inch. The measurement at the rod is actually 2.250" so a STD size bearing should fit then. The old bearing fit tight when...

I also think that having the correct bearings would be the best RAMM, but since I live in Sweden and parts are non existent and I have to order them overseas and that cost a lot. I now already have STD size bearings that fit like they should against the journals. But I have a small gap between...

I cant see why the rod would be out of round if you fit thin brass shims between the rod and bearing half Halifax? Toolmanmike if the engine left the factory with oversize rods with bearings that fit, why would I need new then? Doesn't machine shop sometims oversize crank bore and rods? The...

Hey guys and girls I just bought a 75000 mileage 318. After doing a compression test the cyl 2 failed because a cracked valve seat and cylinder 2 have bad pitting. So I sent the block to machine shop for sleeving cyl 2 because the other cylinders was in really good condition with minimal wear. I...

I have looked at the Lunati 10200702 cam as a possible cam to change to if I'm not satisfied with my current cam. Have looked at the XE 262 and also the 265 DEH as RRR suggested. But think the Lunati seems the most appealing for they are designed to work together with the .904" lifter diameter...

Sorry for a very slow reply. But I have been busy lately. I'm done with the grinding the ports. I have left some polishing of the exhaust ports and maybe the chambers. Have cc one chamber at 61cc. But I'm little worried that I removed little to much at the "short turn radius" at my exhaust...

Thanks for all response in the subject. I feel fine not going crazy at port matching as my starting idea was just to make the ports more even and a little better flowing. As I understand that smaller intake ports helps keep the port velocity up which in that case helps the lower rpm torque? Also...

Thanks for all the opinions and guidance it really helps. I want to make the engine, trans, gearing and suspension work together well. My goal isn't really to make that 275 - 300 hp my goal is more to make we say that I'm going to have 250 hp at the crank. That those 250 hp is utilized and...

I'm going to rebuild my 318 with desire to have much torque from idle and up. I want the engine to be strong and have relative good mpg, after that I want it to be "fast". So in that order I have choosed my parts to suit my needs. I have bought: KB167 30 over pistons Scat I beam rods 302...

Here you have a ballpark numbers from Comp Cams dyno: 320 hp @ 5000 rpm and 368 ft/lbs @ 2000 rpm.

Valve timing open/close on my cam card should be measured @ .006 not @ .050. Got confused because on the cam card it says duration @ .050 so I thought you meant that and I missed read the other text about open/close timing. Will measure that tomorrow. Thanks

Thanks, I understand but I wanted to be sure. "Check your valve timing events @ .050 against the cam card, for good measure" Does this mean .050" before or after max lift or is it .050" up from bottom of the lobe? Thanks FABO

Today when I was degreeing my cam I bumped into some problems and have some questions. The cam is a Comp XE250H and have 106° intake centerline. I installed the brand new Comp Cams timing chain and sprockets with the 2 dots lined up. When I then was degreeing the cam I've got 59° 0.05" before...

Tony20110 This is the right adjusters for the 64-69 273 adjustable rockers. http://www.summitracing.com/parts/crn-99802-16/overview/

My rocker arms on the shaft is very loose especially on the intake rocker arms. This is roughly how big the gap between the rocker arms and the shaft. The gap vary on all of the rocker arms. Is it time to change to new rocker arms? Since I'm changing cam, lifters, springs and valve stem seals it...

Now has the XE250H cam and lifter kit arrived with 901-16 springs and double roller timing gear set. Will take out the engine this weekend mainly to replace all the freeze plugs because one of the freeze plugs leaking. Then going to install all of the above things with new gaskets and then paint...

Thanks Dave for that explanation! Did what you explain and made a flat stock piece with 1 inch between the hole for the kickdown and it didn't work at all. The geometry was way of. But with your explanation my side to construct things kicked in and solved it like this: I had already made a...

peelo how did you modify the kickdown linkage?

I changed from 2 bbl to 4 bbl also. I've made a throttle cable bracket that fixed the throttle cable and I extended the throttle pressure linkage that is hooked up to the carb. I have 0.24 inch (6mm) to much at the throttle pressure linkage rod to throttle stud at WOT. Everything else is right...

Thanks for the input as always Dave. I'm ambivalent about the cam choice. Talked to my part dealer about cams and he recommended me not to chose a Summit cam kit because of it's quality is often poor. But found these instead and the first cam is my favourite what do you think? XE250H...

What would the estimated horsepower be with this parts? Street Demon 625 cfm Edelbrock performer intake 2176 Summit cam 6900: 204 int./214 exh. 0.421 int./0.444 exh. Lobe: 112 Comp Cams lifters 822-16 Edelbrock springs 5877 Summit double timing gear and chain Everthing else is a stock...

Seat pressure: 90 lbs. O.D. / I.D. 1.400"/1.020" spring height: 1.650". It's non rotator whatever that means. Found these Edelbrock 5877 springs cheap here in Sweden do you think those would work? When I change to the Eddy heads the springs will not be used so I don't want to spending so much...

That's good to hear. When looking at Summit on springs it's a jungle and I'm not sure what to look for. Any suggestions? I'm living at the coast so I hope the factory set up will work, but good tip about the Holley jets. I'm impressed by your work Dave :thumleft:

My Street Demon carb has arrived:thumleft: It's going slowly building this combo but I'm going to follow thru. I'm going for a performer intake next. The rpm heads, kb pistons, eagle rods, XE268 cam and new exhaust system coming on. But I'm on a budget for now and I wonder if the performer cam...

I only used a screwdriver to feel when it where on top. Not so accurate but I think it gave me a baseline for now. I only pressure tested one cylinder due to it was difficult to access the pressure gauge. I only tested when cold, disconnected power coil and cranked at least 3 seconds.

Today I have found out that the timing mark has not slipped, checked it like you said 67cuda360. But for now I need a new volt regulator because the alternator charges too much 17-19 volt and some readings high as 20 volt. So i haven't runned it today and checked the timing. I'm afraid to burn...
