Tossing Around 273 Ideas

273, I was thinking roller as well....after I logged off, lol. There is a 88 Ram 50 on CL right now that looks clean and straight as a whistle for $1500.

Wonder how the stock 273 920 castings would work with a valve upgrade? Chambers are closed. I have that set as well.

Was thinking of sticking with a smaller valve to keep from having to notch the bores....not sure how they'll hold up under boosted applications?? Letting the forced induction do the work of the bigger valve....sort of, lol.
