Asking About: Mustang Scat 347 Forged Rotating Assembly - Domed Pistons, H Beam Rods (79-95)



Could I run this kit on a street car with daily use and use 93 octane, sense it is 11:8:1 compression. And will it be street-able. Also one last thing, is this 347 stroker kit give me the most power out of all the 347 kits you guys offer? Thank you.

You would want to run a larger combustion chamber head to keep your compression ratio in the 11.0:1-11.5:1 range. I would honestly recommend 11.0:1 for a serious street car because of the variations with today's fuel octane levels. For a Naturally aspirated engine the higher compression 347 kit will have the most potential for making power on a production block 302. Keep in mind though that the rotating assembly is only 1 component to an engine build. You need to carefully plan out which cylinder heads, intake system and valve-train you are going to run in order to meet your specific goals. It would be best to sit down with a reputable machine shop or engine builder to plan out your build and make sure it is the correct route you want to go in order to meet your goals.

Ok. So could I use 93 octane with no problems. I also am going to put a vortech v-3 supercharger with 10lb of boost and I'm going to run a comp extreme energy cam. For heads I was going to use AFR 185cc intake and 58cc combustion heads. And intake I was going to use a Holley systemax ll intake with a 75 mm throttle body - Tyler 4 years ago

you can not run boost on a high compression motor like that and expect it to live long. If you want to go forced induction you would need a motor with 8.5:1 or 9.0:1 compression ratio. - Scott 4 years ago

Ok thanks for letting me know. If I just ran all motor and no boost would all of the parts work good together. - Tyler 4 years ago

The heads would be ok, but you might want to go with a higher flowing intake like the TFS R series or something similar to it. also you need to talk with the engine builder to spec out a camshaft that will meet your needs. - Scott 4 years ago

Ok. Now if I would change the head and make 10:1 compression would that be a little more street worthy. And would I still have to find a different camshaft because I would like to use the com cam extreme energy - Tyler 4 years ago
