What about just upgading the rods and pistons?
Rather than going the route of a built motor, would it be worthwhile to just upgrade the rods, pistons and head studs? I saw this kit on ebay http://cgi.ebay.com/ebaymotors/EAGLE...spagenameZWDVW
or purchase from a vendor on here. What are the costs involved with honing and installing rods and pistons? Lets assume the engine is already removed and delivered to the shop of your choice. This seems like a less expensive way to get into the FI world and still be pretty safe on a stock block. Any input would be much appreciated. Thanks in advance....

However if you have the ability to pull your motor yourself and do it all yourself to save on labor then nothing is wrong with just doing rods and pistons.. or if you don't mind spending twice on the labor if you decide to do more to the short block then yeah.. rods and pistons are ok.
If you are looking for rods and pistons at a decent price.. don't hestitate to contact us at sales@racemrc.com or visit us at http://www.racemrc.com

Just what I said, I would replace the rods and pistons and retain the stock block. Is it really that confusing? There is a lot more that goes into a built motor, crank, short block, sleeves etc...

Fair enough, makes sense. It just seems like most people replace everything. I just figure if the rods are the weak link, just replace that part and the pistons. Of course it prolly won't handle 5-600+ whp but I bet it would make 4-450 whp pretty safe.

When you factor in the cost of high end pistons, rods, bearings, main studs, the machining and assembly labor....you would be looking at this. http://www.forgedperformance.com/sto...cat=277&page=1
As MRC mentioned, you can save about $500-$1000 by doing all the labor yourself.

to the OP, yanno I was acutually going to do the exact same thing. Im going to replace the pistons, rods and head studs, then go FI. And I'm still going conservative, somewhere around 375-400whp. Better to be safe....

A stock block can handle that no problem...

I recently read that the bearings are considered the weak point of a boosted car. Any merit to this?
