can I run a 408 stroker with edelborck power package with a 8 inch if i drive nicely with the occasional race hear and there. When I say race I mean at a stop light and punch it to about 50 miles per hour. I dont think I will ever see 6000 rpms, I may but I highly doubt it on the street.

 

i'd say it's pushin it

 

Nothing funnier than when a guy pulls up next to me at a red light, revs up his motor acting cool and then the light turns green and I idle away in my 65 and he breaks.

Sure it will be fine but it will let you down one day. That's been my experience anyway.

 

A built 408 is a lot for an 8" to handle. Just remember that if you break an axle under power, you're gonna make a rapid, unscheduled turn.

 

man, now I am way over budget, is their any popular junkyard cars that I can get a 9" from, or is their somewhere I can see a list of obtainable cars with these parts.

 

The question really needs to be asked. Why did you build such a nice 408, but then not provide the platform to be able to use it? it would kill me!

 

Honestly though it is hard to break an axle on street tires going to grocery store...but it is possible.
It also isn't the RPMs that kill them. It is the fast and sudden starts. Auto driveline with a responsible driver could prob work for a while without issue, but it should be on the upgrade list.

 

My dad had a rear in the garage that we measured from bolt to bolt thinking it was a 9 inch. Then someones told him thats not where you measure, so i ended up being an 8 inch. We found this out Sunday, two days after the stroker kit was ordered.

 

Fair enough.
If you havethe 8"there, drop it in the car, and drive it around. You should go easy on the motor when its new anyway, so it should last you a while.
In the mean time, try to find a 9" which will aslo give you the opportunity to select the right ratio (driving around with the 8" let you know if you want to go up or down).
When you then get too excited andthe 8" blows, drop in the 9"
There you go, a silver lining!

 

Just buildthe carwith the 8 for now, if you have an auto it will probably live for some time! If you have a manual, avoid dropping the clutch..

I have a friend who has a 65 with a strong 302, while he did end up breaking the 8", it took a lot of time and abuse before that final drop of the clutch finally broke it.

Make the 8" last, and maybe consider a performance built 8" third member and axles (shafts).Thismay save you a lot of money and time now, and down the road.

Some of the performance built 8" rears are pretty impressive...
