What cam to go with Hyd. or solid (flat tappet BBC)

Copied and pasted spec`s on the engine from one of my earlier post...

Have a BBC 427 (.030 over) forged TRW L-88 (ZL1) pistons that make 12 to 1 with closed chamber heads but am running 781`s (open chamber) so its about 10.8 to 1 and have the larger 2.19/1.88 valves and some bowl and port work... Also the intake is a Performer RPM and BG 750 Speed Demon... It has Hooker SuperComps (35" long tube) with 3" exhaust 2" H pipe and a pair of single chamber Flowmasters The cam is a Lunati 00026 with .549/.558 lift & 232/239 @ .050 (293/310 adv. duration)

Have to change the cam due to a problem with the guide plates and pushrods (have a bad lobe on #5 intake)

So what would be the best replacement for this engine...? 1969 Chevy C10 heavy truck... Has a Turbo 400 w/manual valve body & reverse pattern with a B&M Holeshot 3000... The rear is a 12 bolt w/4.56 Richmond gears & Eaton Posi unit... The intended use is very little street (short trips mainly in town) and mainly strip runs... Maybe 1000-2000 miles per year if that...?

Suggestions...?

If your going to run mostly on the strip i would go with a solid cam. You didn't say if your using roller rockers but i would consider that and use a stud girdle.Best to call cam manufacturer and tell them what you intend to use motor for. They will ask you specs on your truck and let them recommend a cam shaft.

If you have the money for a solid roller that is what I would go with. Below are the cams I would recommend for a solid and solid roller.

Solid
XS274S (236 242 @.050 .568 .578 lift)

Solid roller
XR274R (236 242 @.050 .639 .646 lift)

Either of these cams would work well, If you would be willing to setp up to a 3500 stall, I would recommend going one bump up on each of the cams.
