I am about to start rebuilding my 78 400 motor. Does anyone know were to find some good articles on adding some more horsepower. Thank you.

 

Right here, ask away.

 

Did you look through the Sticky at the top of this forum?

 

This s what I did....

-Howard's hydraulic roller cam in. 217@ .050", .571"/ ex. 225@.050" .576"
-Linked hydraulic roller lifters
-Hasting's moly coated to ring set
-King bearings
-Melling oil pump
-All Felpro gaskets throughout
-Comp dual valve springs matched to my cam (part#924)
-Positive valve seals
-Comp cams 8.903" Hardened push-rod, coupled with .030" shims gave me near perfect wear pattern and 1/4 reload(Howard's recommend)
-New factory replacement dampener, forget the brand
-NGK G series iridium plugs
-Flow-tech ceramic coated headers, 1.75" primaries, 3.0" collectors
-KB2347 hyper pistons .040" over
-ARP main, rod and head bolts
-2.05" & 1.65" SS valves
-1.73 Scorpion pedestal mount roller rockers
-.010/.010 stock crank and rebuilt rods(balanced)
-Double roller timing set, Comp
-Flowkooler aluminum water pump
-MSD pro billet distributor
-Moroso 8.0mm wires
-Weiand Action plus 4v manifold
-Qft 650 annular mechanical secondary SS series+ 1" spacer



This is what I got....

With initial timing at 16 degrees and total at 32, coming in fully around 3500rpm, with an air fuel ratio of 13.46 (peak torque)

500.4ftlbs @3100 rpm
383.2 hp @4950rpm.

Edit: Oh, and with factory open chamber heads

 

One of these days I'm going to learn to read the read first threads, but I don't want to put the SilverStreak out of business. Conumdrum time. What would ctubutis do??
Help, program not responding.

 

Ya can't pass up a chance to brag....
