New to Olds Motors...need advice
Hopefully this is posted in the right forum.....
Hey...looking to see if anyone can tell me if this sounds to wild for street & Strip for a 68 442 Clone. It comes with a rebuilt TH400 Trans. Currently has a 350/350 set up in it. Any help or suggestions would be greatly appreciated.

See below-
Block preparation:
Engine block hot tanked and new brass core plugs/ Federal Mogul cam bearings (1234M) installed. The block was bored +.030” on our precision boring stand. All head and main bolt holes are tapped. The block is then torque-plate honed; honing process is performed in 3 steps; piston to wall clearance held at .006”. ARP main studs (185-5401) installed.
Rotating assembly preparation:
Diamond Racing Products light weight custom forged pistons (2618 material) installed. Speed Pro “Plasma” moly piston rings (R10375-30) installed on pistons, as are Federal Mogul aluminum alloy main bearings (4294M-10), fully grooved; feed hole enlarged to 17/64”. Federal Mogul HD connecting rod bearings (8-3345P-10) and cam bearings installed (all bearing clearances held around .0025”). Competition Cams HD .250” double roller timing set (3113). Competition Cams hydraulic camshaft installed (custom grind: intake lift .584”/ exhaust lift .579”, intake duration at .050” 248/ exhaust duration at .050” 253, 114 degree lobe separation); cam degreed-in to cam card. ARPconnecting rod bolts installed (185-6001), connecting rod caps relieved for ARP bolts, rods are then reconditioned and balanced. Crankshaft is hot tanked and precision ground .010”/.010”. The rotating assembly is precision balanced with damper and flex plate installed.
Components to complete short block:
Speed Pro high volume, HD oil pump (224-41203V) installed with high volume, bolt-on pick-up (15-503) and 7 quart oil pan (15-502) from Canton. Two piece Fel Pro rear main seal (BS40032; 460 Ford) installed. Johnson/ Hylift hydraulic lifters (A-951) installed. Fel Pro engine gasket set utilized in assembly of engine (Sealed Power engine set: 260-1008, Cometic intake set: C5813-060).
Cylinder Head preparation:
Edelbrock Performer RPM cylinder heads (60529) are machined w/4 angle valve seats and fitted with Manley custom “Race Master” stainless steel intake (2.150”) and “Race Master” custom exhaust valves (1.710”) installed. Valves undercut to enhance airflow.
The heads receive “bowl and chamber” porting. This port work includes intake bowl porting, which includes dropping the short side radius and dropping the port floor. The exhaust bowl receives similar port work. The far side of the combustion chamber is relieved to unshroud the intake valve; chamber then polished. The cylinder heads are then milled .030” (71cc chamber results in 11:1 c/r)) then assembled with Teflon seals (Manley 24037). New HD valve springs (Comp Cam dual springs 995-16), keepers (Comp Cams 10 degree 611-16), retainers (Comp Cams 740-16) installed. The cylinder heads are installed using ARP head bolts (180-3600). The valvetrain is completed with Manley 3/8” x 9.800” (25980-16), Harland Sharp roller rocker arms (6005). Edelbrock Torker intake manifold (2730) and valve covers (4485) installed.
An AED 1000 HO carburetor installed. Performance Distributor’s HEI distributor, “live wire” set and wire looms; distributor “degreed-in” for 22 degrees in by 3000RPM plus 14 degrees initial resulting in 36 degrees total advance (not including vacuum advance). AC Delco high torque starter included. Miscellaneous ARP fasteners included, including the valve covers, intake manifold, carburetor mounting studs, water pump and timing cover.
