anyone using lrp sxx stock spec with 10.5 motor?

[09 lex 250]

i jus was curious about this setup.i am willing to try it out if motor and speedo can work well with each other. i currently run the lrp sxx stoc spec with a x12.13.5 and love it!! any info would be appreciated.from my understanding the 10.5 is borderline stock i want to throw it into my 1/10 4wd to try it out

thanks
