Doesn't look like much port work was done Sent from my iPhone using Tapatalk

Take a pic of the exhaust ports from an angle like this Sent from my iPhone using Tapatalk

I guess time will tell. But it has a more generous roof arch than stock. I feel good about it [emoji16] Sent from my iPhone using Tapatalk

I guess my port is too wide too, right? Sent from my iPhone using Tapatalk

One thing I can tell you is the person that recommended these port timings to me is NOT a newb Sent from my iPhone using Tapatalk

Well I'm gonna try and dyno it before too long. Curious to how 36* translates to real world results Sent from my iPhone using Tapatalk

They are dremel bits, called high speed cutters. They tear into aluminum pretty good unless you use much pressure then they clog. But they dull fast on the sleeves I went through two on that one jug

You need that flex shaft, the head on it is thin so you can get it in the exhaust port just fine. And the 90* attachment, I had to cut a quarter in inch or so off the part where you stick the bit in, plus I had to cut some off the bits too. But, it fits in there just fine now [emoji1303] Sent from my iPhone using Tapatalk

Shees gonna scream I can tell you that much lol Sent from my iPhone using Tapatalk

Scratch that, now I remember, I was told by a builder that the extra degree of blowdown would be beneficial in my particular build. Sent from my iPhone using Tapatalk

I thought I was at 35* Sent from my iPhone using Tapatalk

Final numbers are 196* exhaust 124* transfer, with no spacers. The exhaust port got raised about 3.5 mm and widened a lot, lol. Maybe 8-10mm total. This is a lot and shouldn't be attempted unless you have a good game plan Sent from my iPhone using Tapatalk

Here is some mismatch that I cleaned up Sent from my iPhone using Tapatalk

Exhaust port before Exhaust port after (still need to clean it up a bit and throw a fresh hone) Sent from my iPhone using Tapatalk

Ok been doing some grinding. Here are the tools I'm using Sent from my iPhone using Tapatalk

Yeah I bet with a spacer and another gasket my transfer duration will be at least 130. Wonder how that affects power delivery compared to a 124 Sent from my iPhone using Tapatalk

What I meant was, do those sound like typical 4mill stock cylinder numbers? I was tho king the exhaust duration would be higher Sent from my iPhone using Tapatalk

I timed it today. It is at 180/124. I'm wondering if I should leave the transfer duration as is and only go for about 192-194 on the exhaust. Not sure what cpi pipes like, may call cpi monday Sent from my iPhone using Tapatalk

Exhaust port opens @ 90 atdc transfer 118 atdc. I believe that is 180/ 124. Does that sound right for a 4 mill long rod with a stock cylinder? Sent from my iPhone using Tapatalk

And better suspension Sent from my iPhone using Tapatalk

Get a refund if you can. Going .080" over was a bad idea. If you are gonna stick with this setup sell those t-5's and get a set of CPI Sent from my iPhone using Tapatalk

Does this look like a re-sleeve to anyone else? It's 66.5mm bore and it sure seems to have a lot of meat left Sent from my iPhone using Tapatalk

4 mill means the stroke has been increased by 4 millimeters, from 54 to 58 Sent from my iPhone using Tapatalk

I have a degree wheel and an array of gaskets and soon to be a spacer on the way. I will figure it out lol. And I'm not necessarily trying to exactly mirror a driveline cylinder. I'm pretty sure anywhere from 124-128 transfer and 195-200 exhaust will run to my liking. Yes I realize it will be a light switch powerband Sent from my iPhone using Tapatalk
