Well all this time I've been planning a "budget" rebuild for my 400 small block, that keeps getting less and less budget
Now, I'm thinking about moving out of the current Vortec 906 heads. Here's the combo so far:
-400 SBC, .040" over
New balanced rotating assembly, Eagle crank & rods, KB pistons 22cc dish makes 9.8:1 w/ --64cc heads
-Lunati Hydraulic Roller BareBones 10021, 232/242 @ .050, .507 lift w/1.5 rockers (could go 1.6 if I want)
-TH350 with 3000 stall converter
-12 bolt rear with 4.10 gears posi
So, been doing a little comparsion shopping, the Edelbrock seem to claim themsleves champs of the group, but I'm not sure what to think. At this point, I don't really care about a small cost difference, just want the most out of my new combo. Considering the following heads:
1) Large port vortecs iron (not the stock vortec but the GMPP 206cc runner). 65/66 cc chambers, puts compression at about 9.7:1 depending on final chamber vol. $1000/set
2) Fast Burn GM aluminum (200cc runner). 62cc chambers (advertised), should get almost 10:1 with thse $1280/set
3) Edelbrock ETec 200 cc aluminum, 64cc chambers, should be 9.8:1 with these $1100/set (if they have them in stock, if not $1200/set)
4) Also, I'm seeing a 225cc large port Vortec in the GM catalog, PN 25534446. Says it flows 281 @.600 lift, 65cc chambers, $1000/set. Is this really different than #1?
4) Other, please suggest? I've got an almost brand new AirGap Vortec intake, so I'd like to stick with this config, but YEAH, I CAN change this if I want to...
Also, anybody know of better place to get better prices on any of these heads? I live in Lubbock and can deal locally with Scoggin Dickey, but have to pay sales tax so the shipping cost savings gets spent that way.
Thanks in advance!
