Rygen - Please share the specs on the build. If you have to kill me after you tell me, I understand.

LOL.... Okay.. work with me Sport.

Looking at the Displacement alone leaves me with too many variables to calculate the end bore and stroke. hahahha
Displacement = pi/4 X bore(cubed) x stroke x no. of cylinders.

I am assuming that the 8.8:1 Weisco pistons are not a direct replacement and milling of the heads will be done by PH. If you are looking at an 8.8:1 seat at TDC flat deck then the B&S will end out within the same dimensions of the V-8 block. For an 8.8 volume seat @ TDC the B&S will end around 3.55/3.54 respectively.

Do we know the end compression ratio or chamber volume he is shooting at?

It's all good Rygen. I am a noob as well. So here is where I am trying to calculate any change in bore or stroke: Based on what you have said and not increasing the stroke. The math works out to: (I was never good at math though).

4.1 x 61.023 = 250 ci end displacement


Bore: = square root of displacement / (pi/4 x stroke x no. of cylinders)

3.14159/4 = .785 X 3.32 x 6 = 15.645

250/15.673 = 3.955 No change in bore either.

Your task if you choose to accept it is to get the math to work out for me. Either way. The Weisco Pistons look like a great addition to the engine build.

Well Rygen,

The sig pic is what He looks like now. He has no mods and is bone stock other than the K&N and the new Mac SS Axle Back (which we both know yields only about 5 HP, but gains me about what you are packin' with the attitude the sound and droan make).

I have been shifting the AOD manually for a few weeks. The AOD in this lil' stang is stout, no doubt. If I ever had a doubt, I have none now. I would still kill for a tranny dipstick though. (Silly French design there. hahahahaa)

So, with the new Mac droaning I have been floating around town hardly moving out of 3rd and floating between 2,800 - 3,000 to achieve and maintain the droan as well as the "G Spot" on Him. Good throttle response with the DBW at that range.

Here is the bad news my Friend. I am going to get rid of the stang. This has EVERYTHING to do with my finances and nothing to do with my happiness or satisfaction with the platform or the engine.

There are things in life we have to do to get over humps and bumps. We sacrifice for the greater good and understand that with sacrifice and hard work comes reward. This will be the 3rd Mustang I have gotten rid of in as many years. I am sad as hell, but my future financial picture and my current comfort level are not worth the retaining the car. I like paying cash for my cars and on this one I decided to retain the cash to set aside for caring for my disabled very ill mom. After a few life challenges and a couple "pistons blown threw the cylinder wall" of life, I call UNCLE. hahahahaha

I dislike car payments and would rather buy a used Cobra or a GT to modify and have fun with for now. There will be another S197 in my garage in a few years, don't you worry.

So, in a few weeks to a month expect a name change from Jenns05Stang to Jenns98Cobra or JennsGT. LOL Either way, expect me to maintain my interaction and moderation here and in S197. I love all you guys and you couldn't get me to leave again unless I got banned. hahahahahaha

Awesome figures on the engine Rygen. You do not cease to amaze me and as always, you have my utmost respect and admiration for what you have done to this platform's 4.0L engine.

Keep it Real Bud! You are doing a heck of a job and have a great "CFO" who knows the addiction you have ventured into with the Unrelenting quest for the "Performance Daily Driver".

Happy Holidays!

Jenn
