I am in the process of putting together a budget minded 406 with some spare parts I had. Didn't want a full race piece but should be able to drive this combo on the street and perform well at the strip.
400 block w/splayed mains
cast nitrided stock crank
5.7 H beam rods
Ross 95751 pistons
AFR or equivalent heads, 210cc runners
Holley strip dominator intake w/ wilson super sucker spacer
holley 750 carb
1 3/4" headers
solid flat tappet .560" [email protected]
Pretty much the bottom end is planned out. I don't have heads yet. I'd like to fine some AFR 210's or Brodix T1's. I may have some Brodix
-10's I could use. Im looking for 520-550hp, enough to push a 3200# car into the 11's. I could go solid roller if I get a rippin deal on one.
Little eric with the gold 70 nova I did the engine compartment for has a nice little 406 more streetable deal. Flattops, 200cc iron heads, comp 292 with mid lift roller rockers, performer RPM, 750 carb, 1 7/8" headers. Should be a good street motor.
I had also built 2 similar 400 engines for my old 70 nova and my 63 wagon. Both stock block and stock cranks, flattop pistons, stock ported chevy heads, dual plane intakes, 750 carbs, one had a custom elgin cam .470". 250"@.050 hyd flat tappet. The other had a .485" [email protected]
hyd flat tappet cam. Both very potent but very streetable engines. Made alot of torque.
