You want to avoid cams that need high stall converters as this creates heat and heat is a enemy of the transmission and that creates more expensive trans coolers
Not true. While an external trans cooler is IMO an excellent idea for even modest builds, it is not a must.
Buy once, cry once on a quality converter and your not going to have this issue.
Been there done that measured it and cried once.
Worth the wait every time.
