Had this cam and lifters in my 400 based 493 stroker for around 1500 miles. It ran very well, but with my combo of parts, the power band was a bit higher than I was looking for. Really came on strong at 3500rpm. Lifters are USA made Johnson Hylift HFT and layed in the trays exactly how the engine builder removed them. I would really prefer local pickup for this so a guy could check it out in person before buying. Located 100 miles straight east of the Twin Cities. $100.
