Maybe this does not make sense but I think it does. Can I turn Eagle 4340 Rods with ARP 2000 Rod Bolts 8200+ rpms? I have a sbf turbo street car, looking a good set of rods. Camshaft goes upto 7600-8200 rpms. Will shift before that but just asking. Thought about Callies Dragonslayer 4340 Crank with Oliver Billet Rods for comfort though but heard it is too much for what I am doing.

Thoughts????

This was the first thing that crossed my mind lol


I've taken scat H beams and 4340 crank to 7500 but not further. Curious myself if this stuff would go to 82-8500
Seriously I have wondered this myself. If you have a crap valve train then likely not. I know of a pretty well known gray mustang in my area that revs to 8,000 plus rpm but I've heard he has a good chunk of money in the valve train. I know flow numbers don't mean much with a turbo I'm talking along the lines of good parts vs. a lower grade product

I've taken stock rods and a stock cast crank, and cast pistons in a 68 302 to 8 grand.

It didn't make any power, but I got it there...:smt102

And...I won 50 bucks...which is like 250K in constant dollars.

How do I put this? My high dollar short block shit the bed, been considering a more affordable dart block with scat 4340 internals. Only problem is my top end is spec'd to make power in the area of 7500-8000. valve train is nice stuff. don't wanna kill my top end with a cheap short block

I'm good for 7600(shift) but I've got the magic bolts.

Got a 8000 high side & I ain't worried if it accidentally gets there......... Once or twice.

How about more Boost/less rpm
That's what Nelson does with his Mirror Image Turbos? Is that a good idea? His engines top rpms are like 6200 rpms. Should I do that? How would it work on the street just playing around?
