I'm getting close to having all my parts after 6 months of ordering and waiting for parts to arrive. Most people tell me I'll need a 950 or bigger. But on these forums I see some saying they are using an 850 with good results with a similar size engine.

Quick summary of my build. 440 block, .040 over. ~10.5 to1 compression expected. 4.25 stroke, 6.8 rods. Trickflow trackheat intake ported. Trickflow 270 heads. Jones or Bullet hydraulic roller cam. (Got one from each, long story.) Cam will likely be 253/260 @.050", .390"/.390" Lobe Lift, .624"/.624" Valve Lift, 114 LSA. TTi 2 1/8th step headers. MSD billet distributor w/6AL. Car is a 1969 GTX, ~4000lbs. Dana 60 4.10 and hemi 4-speed.


Thoughts on this carb meeting the need?
