400 stroker cranks
echo -- what kind of power did that low deck 540 make. I was looking to run a solid roller in the 650 lift range with a low duration. backed up with a pair of middle of the road heads and keep the RPM under the 6500 range
Would love to make a 700hp 700tq motor or a 650hp - 700+tq pump gas street engine
that way I can run a sub 4.10 gear with my 32x14.5 tires and my 727.
IDK, hasn't been put together yet. It may well not work worth a damn, but I know it's been done before. I don't have a bunch of $ into it and if it's bunk, I'm only out a crank, all the other stuff I have fallback plans. I have an evil scheme and big tires in mind for this one. Here's another guy's project.

I'd expect with decent heads, MW Victors or -1's(spit) it'd go 700HP without even serious porting, that's only 1.3hp/ci. If I didn't already have the Victor heads, I'd seriously look at B-1's, they're made for that sort of combo. Yeah, they're a little $, but the simple fact is that if you're buying everything from scratch, it's not much more than anything else, and you're 30-40cfm and a nice small (65cc) chamber ahead.
That said, this is a lot of engine. For choice, I'd go with a 4.25 or 4.3 crank combo, those fit better, with less massaging, and are proven off the shelf(OTS) combos. Still more torque than you can plant. I have a B1, EFI, mega block, dry sump, custom everything project that I've been working for four years now, and OTS looks really good at this point. This is really marginal with a stock block IMO, even with aluminum caps and a girdle. Read that as, don't be surprised when something cracks and you come out to the car sitting in a puddle of various fluids. I accept that, I have my reasons; it's racing, stuff breaks. If it doesn't break, you're not pushing hard enough. That said, the BCR girdle/mains setup is premium stuff and probably the best chance to avoid driving over your crank. The Pro-gram and Dvorak cross bolted stuff seems logical too, but the theory behind aluminum caps makes sense in this instance to me. I may be all screwed up. Wouldn't be the 1st time, lol.
