Two of my 440 blocks at the machine shop just came back magged and checked out fine, so I'm looking to start getting parts. I have no connecting rods for them, so I need to either get a set and have them refurbished or buy a new set. Not sure how much power a stock set can handle, so wondering if using 50 year old parts for an engine is good or maybe see if there are some decent aftermarket I/H-beam rods I can get. Unsure of how much power I need to make, but one motor I do plan to build is for a heavy, all metal car (guessing weight to be close to 3500lbs+). Any suggestions would be appreciated.
