big block pro comp heads

want my engine to last a long time its been a financial sacrafice to build im gonna lauch at 3500 and shift at 6500 if gear ratio is to steep i will change it you tell me one rotation of tire to 5 plus rotations of the drive shaft and looking up the gear ratios that 8 3/4s came with think its 5.17 i didnt pick those gears came with the car.

The Bare Edel Victors come with the same machine work required as a bare set of ProComp Victors...... I know its still LOTS cheaper... I use these heads myself! I LOVE them!
I use the MP .590 cam and EDM oil thru lifters. Custom pushrod lengths are required for this setup too.
My build is very similar to yours,,, maybee more comp, but that's about it.
My build is this:
440 .030" bored
Steel Crank
H-Beam Rods
Main stud girdle
.140" domed forged pistons
<BALANCED ROTATING ASSY>

.040" thickness head gaskets
Victor procomp version Heads
1.6 ratio rockers
EDM oil through lifters
Custom length pushrods
MP .590" lift @ 1.5 .6293" @ 1.6
Double roller timing set
Edel Victor Intake
Holley 4150 850cfm DP carb "TO SMALL!"
8qt oil pan
sheet metal aluminum valve covers

With this said,,, I can tell you that you'll want to go right into a 4500 1050cfm Holley and use the 4150 to 4500 adapter. This gives you the CFM it WILL want, and also takes place of the 1" spacer the big blocks like with Victor Heads.
looks great are those pro comp rockers looks like they are what do you think of them hope they hold up read some crap about the early ones and good things about the new ones did you have a problem with spring clearance thanks Roger
