Is it safe to rev to 8k on stock block

[sbeck]

I am going to be putting a larger turbo on and will probably be finding my gears way to short and will probably have lot of power left beyond the 7k stock rev limiter with stock cams and valvetrain is it safe to pull up to 8k? I plan on putting in some of the ARP rod bolts for some insurance on the bottom end but I was unsure on what most people feel is safe for RPM's on the stock block/head.

With stock cams power will fall flat after 6k anyways, don't bother...

^agreed. You never want to over rev if you don't have any power up there. If you would slap in some 280 cams or larger I can understand, but on stock valve train the power will fall and you won't be any faster.

larger turbo and more boost means you may need to attending a driving school, or learn how to shift faster.

The factory rev limiter is there for a reason!

yes you are right. it's there to protect the idiots who don't know how to drive. you want to shift about 200-300 rpms past your peak power point for maximum performance.

If you do take it to 8k only do it in 1,2 and 3(I prefer you dont take it that high anyways)......4th and 5th are to long to run 8k with a stock bottom end it is to much strain on the rods. If you do that motor wont last very long.

ya no need to bother! build at least the head at very least and put in some good cams and then go for it! stock bottom end should hold it!

this was not offering a solution to his question.

you sir would get the ratard award.

Actually a combo of all these answers are true. You can shift your car at 8k but, you have work to do before that.
1. new cams ground for your power range
2. stronger valvesprings, better retainers, find titanium ones
3. build the bottom end, these blocks are supposed to be stout but, you do not want to find out it they will take that pressure, new rods, pistons, I would machine the block
4. porting of your heads, intake manifold, TB make sure you are getting the proper air flow
5. fuel, make sure your fuel systme is up for the demands you are going to place, you do not want to go lean at 7k RPMS
6. one good tune, make sure somebody knowledgable is tuning your car
7. Good clutch and flywheel, there are more demands put on this as you rev higher

It is just not a thing where, "I want to rev high so I am just going to bump up the rev limiter" There is alot involved in doing this. Just not slapping on a new turbo.
