I have bought a 4412 holley that they said was a Blake that C&S had rebuilt and it has 79 jets, 50 Acc pump, stock venturi and choke horn. My questions are: Does the 79 jets seem high? From the others that I see out there have all had 73 jets. Which is better a 30 or 50 acc. pump (why?) and does that effect what jets you use? Any other help would be appreciated?

I am using a .030 over 400 with a 327 crank (352) with large domes and an Elgin 1090 cam(in. 537 / ex. 557 lift and duration is 256/264 @.050 with a lobe center of 106). The cam is dialed in @102.5. It has a set of 2.05/1.6 angle plug Wold Product heads and 134 autolite plugs (I use these because the pistons go way up in the combustion chamber) with headers. It has a victor jr. intake with a turtle in it. I am going to run it on a fast 1/3 mi. track that I was told you have to run the same gear as another local 3/8 mi (6.00-6.20). It is going in a 3500lbs steet stock with a direct drive powerglide. If there is anything else that you need to know, let me know.

no...we run 90's. What's your power valve size? that plays a big role!
