NOS Question

bigsteve · Jul 21, 2009

I am a new member and have a question about the HP capabilities of a set of GM's pink rods with ARP rod bolts. The motor is about 390 HP and I am putting on an NOS cheater system capabile of another 250 HP. GM says these rods are good for 450 HP. I know the weak link is the bolts. With the ARP's how much do you think I could spray it safely? It has 4 bolt mains, forged steel crank and forged pistons. Thanks - Steve

dont know about the pink rod's . but i did put together a bbc 427 with 3/8 rod bolt's not the better 7/16 . i used arp bolt's and sprayed 150 all the way down , shifting at 8000 , and have well over 40 pass . no problems with the rods or bolt's but i did freez 2 pistons to the pin. i whent cheep and did not put in floater's that's why im runing this junk a** 396 now . BLOW OR GO BABY.

I guess I forgot to mention that it is a 350 SBC #-o

i've seen them last in the mid tens and i've seen them fail in the high 11's. With stock stuff it's kinda hit or miss.

I would say 150 is safe for the most part. but you never know some people break nice parts lol. I look at it like this its not if it will break its when lol. I have seen people spray over 200 on stock crank and rods here and run low low 10's so good luck lol.

my buddies hitting his with 150 on a stock crank, x rods and cast pistons with no problems in a 383.

I think I'll try it set at 150 and watch the RPM's. Sounds like a hit and miss. I'll let you guys know. Probably be a couple weeks before I get to the track. Wish me luck.

Research for baseline Timing, Jetting, fuel & fuel press. So thay your first n2o pass is not your last.
