stock bottem end ?
stock bottem end ? so i plan on putting in a cam and upgrading to stock 243 heads, the heads will have new aftermarket rockers and new 675 lift springs from tx speed and new chromoly hardened push rods, plus all new bearing's and arp bolt's. i already have a fast90/90 ported and slp maf,ud pulley,lt ngk plugs and msd wires im also added wiseco domed pistons. my question is will my rods and crank be ok ?
The stock rods and crank can handle considerable horsepower (maybe 900 if I recall correctly) but are subject an rpm limitation. If you plan to run high rpm (compared to stock) you would want to look at Katech or ARP rod bolts together with resizing the rods to match the increased fastener strength.
Supplemental edit: Given the cost of Katech/ARP bolts and the cost of resizing, you may want to compare the cost of aftermarket rods.

Stock rods are junk. If your planning on putting pistons in it. Spend the little extra and get rods. Trust me, do it once and do it right! Good luck with it! I also would run stock rockers. IMO its wasted money unless running a solid roller or BIG hyd roller.
Yeah why would you go thru all the trouble to put new pistons in but keep the stock rods?
Definitely upgrade those, even a budget rod will be significantly stronger and will only run you 4-500
