I am wondering what kind of rpms my motor would hold up to and what kind of longevity and power should I expect.

350 2bolt block (bored .030 over, square decked, line bored, completly done)
Eagle 4340 crank
Eagle I beam Rods
JE pistons and rings
11.7 to 1 Compression
1% over balance

462 Camel Hump Heads
Ferrera Stainless Valves
1.94 intake
1.6 exhaust
Comp valve spring (stock size prt # 291-16
Comp locks, retainers
3 Angle valve grind
little blending work
3/8 screwin studs

I think I cover it all. I am racing on a half mile asphalt track. Thanks IN advance

The thing that you have to worry ablut in most chvy motors is rod bolts and rods and piston to valve clearance. Change your springs at midseason. Keep your oil changed and run your valves once a month and that motor should last all season with no freshening. As far as rpm's go "whatever it takes to get to the end of the straight away". Seriously I have seen the same setup go past 8000 all year with no problems. Hope this helps.

I once read an article about John Lingefelter (very large in the engine modification world) he said " a stock small block bottum end is good to 8,000 rpm's with no help" I suppose that means anything above that and you'll get into some problems, I have a 383 that I have run at 6500 and haven't had so much as a burp. It was in my drag car for a couple of years and now resides in my limited late. I love that engine.

When your turning that high with stock stuff, are the rod bolts stock? That's the only thing that I've been to do is put ARP rod bolts in.
