Pro Ram+DFI vs HSR+C950
 

I have done a number of searchs and havn't really found the info i am looking for. The set up this will be going onto is a ZZ4 shortblock, Trickflow heads, 246/254 .558/.558 on a 112 is the cams specs. the trans that will be ran is most likly going to be a T350, i am unsure of which one will be better for my setup.

what is the main differnce between the two? I will be buying everything, The car has a single turbo 231 in it now, that is carbed. so its kinda a big swap.

Since this doesn't appear to be one of these cars, but rather an early 80s Buick Regal, hood clearance won't be quite as much of a problem as it might otherwise be.

There's no particular reason that you HAVE TO use the Accel electronics if you use their manifold; or the Holley electronics with theirs. The mainfold is just a lump of aluminum, the electronics aren't interested in its shape. Use whichever manifold fits your Buick the best, and whichever electronics do what you consider most important the best.

For that matter, there's no reason you couldn't use either of those manifolds, or a MiniRam or whatever, with some totally other electronics such a FAST or Big Stuff or MegaSquirt or Edelbrock, if one of those happens to suit you better.
