In the early 90s we had a 499ci with a set of 906s that my brother ported, an M1 /with a 9375 1050, a solid lifter cam and 2" fenderwells.

On it's 1st outing at ATCO, in ran a string of 10ohs at 135 change. The car had SS prings, footbraked and weighed 3380.

We never dynoed that one because it was just a lowbuck streetcar. Your engine has to make more than that thing did.
