429 rpm's???
A good buddy of mine just finished stuffing a '72 429 into an 88 t-bird with a 4 speed.
the engine is an all stock short block, the bearings were within ford specks so he didn't touch them. the heads are '70 dove heads, with a compression ratio of 11.5 to 1 he says. he also bought a wieind dual quad set up with 600 cfm holly's.
so my question is, today we took her out for the first ride and it will hit 6 grand with hardly any problem, i have heard that the stock rods are pretty good at bending and breaking at hi rpm's. I was wondering what you all thought about it. should we be worried about the rods???
good motor, just not a ford gasser guy.

yea i forgot to mention he had a pretty good cam too.
well 7200 is way the H*ll up there never even hit that with a small chevy. but it is nice to know what other people are doin with there's. this thing is purely a mean looking street machine and i am sure it will get rodded hard so nice to have an idea. thanks

true.
we will be at Car Craft Summer nationals this summer so maybe there.
what do you think about a 460 he built a pretty good one for his dads trucksame thing stock bottom end but he set the rev limiter at 4200. i think that one could go more, my 454 will hit 5 no problem.

I wouldnt see youd need to go much over 4000 then, Id stick with that, but, I love the sound of 7000+ from a big block too
