Inliners International Forums General Discussion Engines 292 advice needed

I have a '68 C/10 w/ 292 and SM 465 tranny. (Bought it when I was 23 -- won't say how long ago that was) The 292 was GM's best kept secret. A real torque monster. I rebuilt one in 1977 and ran it for 25 years and/or 250,000 miles. Only major mod was a .030 overbore.
Currently I'm breaking in the original block on its first rebuild. Once again .030 over [296 actual CI.] I went with 1.84 intake valves (like on a 307 V8), ARP fasteners, Crane cam -- mild stage 2, Rhoads lifters, Clifford headers, Offy intake, 4 Barrel Holley 390 cfm, Centerforce clutch, 465 Muncie was rebuilt, Ign is stock points w/ Mallory voltmaster coil -- Pertronix set up in the near future. Rear end is 3.73 w/ Eaton Posi. Originally equipped w/ 7 x 17.5 tires. Rims that size are NLA so I went with 16s and 235/85 dunlops.
With a 5.38 rear end you won't be on the freeway much, but it sounds like a neat project. Good luck. Welcome aboard.
