The last 10 years shifting between 7000 & 7500 with that 30/30 cam , all stock bottem end , well I guess stock rods don't last forever, # 4 rod out the side of pan saturday in burnout box 8/2/2014, they were the good 327 rods 1966 L-79. ARP bolts . Time to build 327 #2, They are great motors !! P.S can't belive they lasted this long. Gary M
I always ran the 327 X rods in my small journal, steel crank 331" engines ...... but first they were mag'd, beams polished, shot peened and resized with ARP bolts. Knock on wood, never windowed a block or pan. Great little engines, this is the last one I built but pulled it for this 507" Cadillac
it's an MTS (Maximum Torque Specialties) single plane ..... and yes I know a single plane isn't the ideal intake for a street cruiser but I just couldn't pass up the WOW!! effect it had on me. Idled nice on the dyno after a hour hour cam break in session, then pulled 535 torque @ 4300 and 466 hp @ 5000. Ought to be fun in this.........
You know I was looking for a 401/425 nailhead but just couldn't find one locally so I continued surfing and found a Cadillac website. I bought this engine and T400 for $300, it had been rebuilt with about 30k on it when it was pulled. I replaced everything except the pistons, the cyl. still had the cross hatch but I had the machine shop hot tank and kiss the bores with a hone and take .015 off the deck.
The crank was 10-10'd and polished and I purchased PEP ARP cap screw forged rods which I polished the beams and had them shot peened and resized. I started a pretty extensive home port job then had Pontiac 2.11/1.77 stainless valves and guides installed.We took .020 off the heads shooting for a compress ratio of 8.7 -8.8:1...then I finished the porting job by CAREFULLY blending the ports into the new seats.
The cam is an MTS 228/234 flat tappet and I used their shaft mounted roller rockers, push rods, intake, water and oil pump and a bunch of other stuff to make it more reliable. The carb is a Quick Fuel Tech 780 with a 1/2" 4 hole spacer, an MSD dist and Taylor wires. These Cadillac parts are kind of expensive but I sold my 331" sbc / 700R4 for $5300 and I have about $6700 in the Cad and totally rebuilt T400....not too bad considering.
Sounds like you hit everything except making it roller. Very nice
To OP, sorry about hijacking. I started reading this because I just threw out a set of original 68 rods out of my son's 327 becuase I realized that there was no way I would use them or give them to anyone to use in any type of performance build because quality, low priced, aftermarket's are so cheap for SBC's.
I think it is pretty impressive though if you had a set last for as long as it did running 7K + rpm's. It just sucks that you turned it into a boat anchor. Well, were you lucky enough to save the head(s)?
So how bad did it hurt your motor?
Although large journal, the rods in my 307 were in its previous owners build. Was told he took it to 7,000+ "all the time". I had em shotpeened, new ARP bolts and resized. This build will see 7,000+ also. If the rods live I'll either buy new I-beams at next freshen up or "retire" the motor in an S-10 or something with a millder cam (and lower revs).
