I've had more bad race converters than good ones, I ended up finding out that a very good 8 inch race converter from Turbo Action was the best converter I have owned. It was made for a SS/AH back in the late 1990s, that was a GREAT street and strip converter. It would drive away very nicely from a dead stop with very light throttle pressure and set me way back in the seat when foot stalling it up around 3600 RPM before flooring it at the races boogie up
Paul Rossi use to test converters for Turbo Action and he made a comment one night when testing at O.C.I.R years ago, he said you are truly blest when you get a really good converter shruggy work That was back in the late 1970s shruggy

It is big enough to make good top end power, but it will also drive really nice with a typical high stall street converter. It isn't a race cam so don't buy a race converter, just stick with high performance street parts. Call Porter Racing Heads and tell them what you're trying to do and they'll get you the correct camshaft for your application.


I think I'm going to take your advice and go with the MP528 solid cam. Will it be a direct swap for the Howard's cam/lifters I have now or will I have to change the pushrods as well? I had installed new Trend pushrods when I installed the Comp Magnum rocker arm assemblies.

I've been looking for a 528 Purple Shaft to no avail. I'm starting to think about maybe going with a hydraulic cam instead. Based on the specs I posted above on how my engine is built, I would appreciate any recommendations on a hydraulic cam that would be a good choice for my engine (is there a comparable hydraulic to the 528 Purple Shaft?). Again, I won't be taking the car to the track and I don't want a real high stall converter. Maybe 3000 rpm tops.

If the converter is too tight (low stall):
ragged idle in gear
fights the brakes
stronger shock to the axle on shifting > loss of traction

I also like the old MP.528 solid. I'm running it in my 440 Shortram motor. I use the factory hi stall convertor with it and it works very well.
