I haven't seen a 'pure stock' dyno of a RAIII since I think it was 'Musclecar Review' did their couple ages ago;
It would be nice to see if you observe variation from their dyno...

Well, since Dan dyno'd those RAIII & RAIV engines for MuscleCar Review way back in the late 1990's (dang, it seems just like yesterday!), we have a lot of good information to compare with for this RAIII. We were thinking that since my '70 small valve XV code 400 made 380+ hp and 450+ lbft. of torque with log manifolds, 9.95 to 1 compression, and the 2801 cam, this RAIII should be in the same ballpark power-wise. It gives up a little compression (9.65) and slightly less cam but has RA manifolds and large valve heads. It'll be an interesting comparison for sure.
