This should be a cool build! Should make plenty of power to move an early A!
I've still got two complete 170cuin slants in the shop. I keep daydreaming about a 210cuin stroker! Should rev to the moon, if you can get a head hogged out enough!
Or power adder. I have had some of my stock short block 170's to about 7,000 rpm on juice. But I don't reccommend that except on rare occasions. Need some good internal pieces for repeated excursions up there.
