6300....

 

thanks for all the input everyone. im just trying to take into consideration when the motor will be when its most powerful based on my cam choice and all...

 

I know you can upgrade the motor to take the rpms, but what about the tc and the tranny. Are they realyl designed to spin that high or have the bands clamp down on gears spinning that fast?

 

i have never heard any problems with a tranny spinning too fast...v8 has stock rod bolts and stuff and he spins to 6800....i know my tranny will go, thats just a matter of time and im pretty sure the converter will be able to hold. its a 3200(3400). i have finally come to decide on the F5 on a 112

 

on my truck with the cam i got now 6400..on my tr224 112 lsa im hoping for 6500..
no wim my dirt track car its a 355 sbc and i turn it any where from 7200-7800 depending on the track and gear i decide to go with

 

yea with the 224/228 112 i plan on shifting about 6600....hopefully everyone is right and the rod bolts hold past 7k

 

well i would have to ask on witch motor i have been through so many



well on my 5.3 they have seen 7k and sometimes 7400 with rod bolts i belive they r unhurtable.

 

good deal, i dont plan on upgrading the rod bolts, if i needed to with that cam i would jsut go smalled because thats way too involved

 

dude that is as easy as changing u'r plug and wires i would not turn a motor more than 6200 to long before changing rod bolts.
i know their r some people turnning stockers 6400 r 6500 but i would not do it.
rod bolts r the weakest part of this whole motor!

 

if you can please explain why they are so weak, if they are so weak then how come ive never heard anything to this site
