Best hydraulic flat tappet lifter?
By chance, got cam card , on file ....or at least a grind number ? Crane Cams ,are usually really good on valve train. I'm curious what grind you are looking at ,and recommended open and closed spring pressures.
Either Crane cams
693511 or 693901 and crane 693801 (have to finish my Mopars in 5 months prior to retiring from sub service 31march) 2 aspens, 2 roadrunners, no more for another half to full decade.
I am swimming in choices, pistons: have 2 Speed Pro H116P and (1) 405 set. 273 adjustable rockers, stock, Chinese 1.6 stainless, PRW stainless 1.6, & used crane gold roller rockers for the W2's (I bought the W2's YEARS ago).
I might might might still have 95% of a W2 long valve econo set up, 675's, maybe a set of 360 heads, and the Chinese aluminum bare heads Ebay had for $414 a pop. The plan is to build two street engines and drive all the mopars from the east coast of I-10 back home to San Antonio.
