You can try TPI specialties in Shakopee, they claim a lot of knowledge about that vintage. https://tpis.com/

Personally, I would not do two changes at the same time based on hunch, if things are close, as you will not be able to tell which caused any change. I think I would start with mixture if you look a...

Which Holley model do you have? I downloaded some software, but it won't show the table unless you have a pcm read or file, it appears. It would be interesting to see what you are dealing with.

Does the Holley have a wide band O2 option? Can you add fuel per cylinder over the whole rpm range? If not you may want to invest in a wide band monitor that lets you log data. Especially when you...

If you call 1.00 the nominal center of range based on whatever, 1 and 2 are much further off at a idle than 7 and 8 are. It also appears all but 3 and 6 moved closer to nominal at higher flow and...

Here is the screenshot of the two by cylinder fuel trims you can set. Idle is probably for about 580rpm or so, and the off idle I have heard a couple of different highest rpm covered, but probably...

You can get a bit of an idea of how it works out by looking at the fuel trim by cylinder at idle and off idle in the programing. One of the procedures I have seen for setting those numbers, if you...

Personally, I have found cam information from many sources to often be not the best choice, for me. This includes some high reputation engine builders locally here in Minnesota. I think what...

I can get you one from our 1996 RMW, which is OBDII but very little different from earlier, it appears. I would be off my DST tuner program read so a screenshot on the computer.

Will that work?

I am going to intend to keep it OBD two. I had already ordered a Caprice PCM programmed to specific VIN on GM software so the DST would recognize it as Chevy, when I got a solution to problem with...

I looked around a bit to find out what cooling setup he is using and couldn't find anything. Anybody heard what he has on the Grub Worm? Still reverse flow?

Just received the DST tuner and got a big surprise. All went OK to read the PCM, but when I go to use the tuning software it says the calibration is not supported. Jet says the same, so sad, too...

Thanks, I appreciate it :D

I just looked at my factory service manual to see what the give for stock piston clearances. It shows .001 to .0027" with a wear limit of .0027 (gotta love that new...

I may try to dig that one out, although if it is an SAE paper it may now bb pay for type.

What I was hoping to find out was if there was anything the compared the piston and cylinder wall temps...

Glad to see the 4032 pistons for low expansion not only because of growth up but also because you can fit them tighter so they rock less. When I was asking about short skirts, I was referring to...

Thanks for the reply, and I will be eager to see what you get for an an answer. I posed a similar question to the shop that will be doing my machining. They are also a high end race engine, muscle...

Has anyone done any testing on various dynamic compression ratios in the LT1 gen 2 engines, particularly the iron head models?

I ask because I have been finalizing specs for my new engine build...

I am finalizing the engine upgrade design for my 96 RMW that is a daily, hauler, cruiser, tow vehicle, errand runner, all of which don't add up to many miles per year as we are retired. Not usually...

I have had the 96 wagon since 2013 and been a long time lurker here. Painted it last year over the winter and this year am going to do the drivetrain, engine, trans, and rear axle.

Long time...
