just checked my messages thanks for getting back, how is your trans holding up/ what is your stall speed/ est. h.p. level of engine. I am building a 521 bb, p-51 roller cam, est. h.p. 550/625 h.p.another question, if you have a 3000 stall converter and hit lock-up it will l/u at 3000, what if you back off throttle at speed and the converter slips back to say 2000 rpm, them hit l/u, then go back to cruising throttle opening, will this give you a lower cruise r.p.m.? thanks, stevo in corona, ca.
