I am putting my 4bta together now. It's got a he351cw turbo (very similar performance to a HY35W, many mods on the VE pump including a 3500 rpm spring. Marine high rpm valve springs. Stock injectors for now. Powerstroke IC, 4" low restriction air fliter and associated tubing. all 3" tubes for compressed air from the turbo through the IC. Bored out the intake manifold cover to 3" and installed 3" inlet. Full instrumentation ( pyro, boost, oil temp plus the normal assortment of standard gauges) I will not be constantly beating this thing, but do intend to take it to it's limits every now and then.
The question: Who runs their engines at this rpm, and do you have HD rod bolts? I can't find them from ARP or Cummins. If you use them, who makes them, or better yet, where did you get them? The guy that built my pump builds pulling motors, and only works on 6bt's and 4bt's. He said I will have NO PPOBLEMS if I keep it under 4000 rpms. Please comment if you have any experience in this regard.
Thanks,
Bob B.
