Larry ,
We built these and many other stroke combinations in our shop years before these kits became available. Some combo's are better than others for specific performance goals. With the KITs available it is a plug and play build except the needed clearance issues.
If you are comfortable with areas that MUST be checked then right on- build away. Forgetting to check or grind enough clearance on pan rails - bottom of bore on block and , makes for broken parts.
You can build it and be very happy with performance. If not sure about all needed clearances and if 0.060 will work on bore to rod instead of 0.080 then get help. BTW a big paperclip is about 80 thou and is a must for rod to bore clearance. You can also spot weld paperclip to end of 1/8 welding rod to make easy ,quick tool to verify clearance you have to grind to get to 0.080 in that area.
