Here is what I have decided to do! I am going to put it together to get the car all sorted out and turn it no more than 6000rpm. Then add new rods and lighter pistons Vic. intake Custom solid roller cam and let be.

I would run that engine it will last a while until you build something better. I ran a similiar setup in 1964 galaxie but with trw domes with domes machined off stock truck rods and bolts with no miles to 6500 for six or seven years.I had a lot of fun with that motor. Laughing

In 2003 I built an offset ground Ford crank 501 engine for a guy who bought all kinds of parts from people who had engines which blew-up.
It has H-beams on one side and I-beams on the other ... SRP 4032 pistons on one side and Ross 2618 pistons on the other side; (even different material); at least the rings & bearings were new.
A429 heads and Lunati street roller cam with a victor and 950HP carb.

It is a street car, (66 Fairlane), that he takes to the strip about 4 times a summer for fun. I sent his lifters to get rebuilt for the second time this winter. He DRIVES this car and has almost 20,000 road miles, too.
Changes his oil and filter whenever it looks a LITTLE dirty and he is constantly tinkering with the rest of the car; (in 2010 he put in a 700R4 with a TCI valve body using a Powerglide kit so, he had an overdrive for highway cruises).

As long as the specific parts are not overstressed, mismatched doesn't mean a thing.

Mike, Glenn took meticulous care of all his stuff. You should see his garage. If he says he didn't rev it above 6k, it never saw 6100. He told me he ran that engine for 3 seasons(IIRC). The last owner couldn't have run it for very long. I think you could run it for a long time at 6k.

Have fun.

My experience from yesterday

Post  460Dave on February 3rd 2013, 9:48 am

85 T-bird, 3,000 lb, 315 radial, 4.11 rear, glide w/brake. P-51 headed 466, mech roller, stock crank, stock football headed rods w/ ARP 2000 bolts. Best ET 10.09 @ 134.67 mph. 25 passes. Yesterday, 1st pass ran a 10.67 @ 126. It was knocking at the top end. Drove it back to the pits with everyone looking at me like "Dude! WTF!" Tore it down last night and found one rod bent like an "S", bearing beat out of it. Rod didn't break, but it sure wasn't straight. The rod was still bolted up, but the little end was pushed hard against the piston (sideways). The piston had some scuffs on it, but still looks "together"

That is the only piston I pulled (it was midnight) but with the engine on the stand and upside down, the rest of the rods look straight.

I typically left the line at 4000 rpm, shifted at 6500 and had a 6700 limit chip. Rods were "race prepped" as good as you can possible prep a stock rod. Rotating assembly was balanced and pistons were the TRW light weight forged flat tops. 678 gram

oh, additional find. When I unbolted the oil pump, I found one ear broken completely (Stock, Melling pump)

BTW..... looking for parts
