well you can get big engine to rev. i have many from 468 to632 my 632 will rap up to 8000 no big deal . as for the rods why wast your money on L-19??? bolts .the 2000 are ok.i have used them many times as well as ARP 8740bolts well before the bolt will fail the fork end of the rod will move and do .as for 7000 rpm that not hard if you run the right clearance on rods mains .and piston pins . as for speed pros if your going past 7000 i would use a SRP/JE.ROSS.MAHLEY.CP or a KB forged piston is nice for the money and very lite. speed pros could work but are abit heavy and with the cam your looking at you going to fly cut them .for your CID just 030 over on the truck block is not much i would bore it to 060 and a 454 crank that way you could get some CID as well .if not the 454.4000 storke then check walls and bore it to 100 over alot of the truck blocks are thick. as for the cam size for the i built and used cam that size on the street . i have a 276.6/287.5 @050 741/745lc112 and have used some a round 680/680 270/280 lc110 and smaller. for valve springs i use PSI in many builds as well as the isky #9685 240@2000 open 685. i do get very nice soild roller cams and PSI spring as well as the crower hippo roller lifters . so this stuff will work on the street. i have done it for over 20 years .but do not think your going to put big miles on this stuff with out looking at it from time to time .as for the cheap pro comp heads .or patriot heads they will take some work to make them nice and the pro comps need a very big head gasket to get the chamber to seal up over 4.530 i have been told from more then one guy. thats work with them so a felpro head gasket 1017-1 may seal it .on the last build i came very close to using them but doing lot of looking in to it. i past and use a set of darts by the time i spent hours= money to make them work the darts were a bolt on with not much tune up work and flow good numbers
