Street sweeper. 236/240 111 lsa. There was a 346 Vette that made 511 rwhp with this very same H/C/I setup. Now I have no illussions of making 500+ through an auto but 450 rwhp @ 6600 or so is possible.

We routinely spin stock shortblocks to 6800. You have wayyyy too much cam to be squemish now...

Seriously, as long as you let the engine warm up and I mean get the oil above 130 at least before you beat the snot out of it, you should be fine below 7K. I usually put in ARP pro series if I want extra insurance or to go 7200...

Why is it going to cost $750 for rod bolts? sorry if this was answered already, I didn't read the whole thread.

Thanks,
Shane

I shift @ 6700 and have bumped it off of the 6850 rev-limiter countless times. It has never missed a beat.

That's what I'm thinking.

Excellent info. Thank you.

I was told to estimate the rod bolts at $150 and then the shop wants $600 in additional labor costs for the added work of removing the engine and putting it back in. Yes they are aware of how the rod bolts can be done by lowering the K member but they said if they are gonna do it then they would rather pull the motor and not mess with the alignment.

The labor makes total sense. We sell the rod bolts for $99 I believe. I will not do it in the car either...

Only on my back at the track with the car on jack stands...

Then why are you bitching about having to compromise with a 380 dollar part for 2 full seasons?

I have no idea what $380 part you are referring to since it would/will cost me $750 for rod bolts installed. And I'm certainly not bitching. I started a poll asking what RPM people would feel safe shifting at with a stock 99 shortblock and maybe what personal experiences others have had. Where is the bitching in that?

Then a few people felt the need to come in and give me ****. Why? I have no idea. They must have had nothing better to do.

Yeah I know

But lets be honest. They are only doing it for that price because I bought every part from them and all ready have a lot of labor fees on the original order for the heads,cam, intake, fuel pump and even the roll bar. It's easy to justify cutting a break with someone you're all ready making a lot of money on and know will be back later for more.

My car has 413whp with 109,000 mile and my Rev is at 6800 and been that way for 3 years. My best E/T is 11/6@118mph with boltons and TSP 231/237 cam. Stock rod bolts do not need to go any higher than 6800. I dog my car every day and he the rev limiter every now and then.

Thank you sir. This is exactly the kind of feedback I was looking for. I think I'm going to spin 6800 on the stock bolts and see how she does. I'll put the $750 away towards the new shortblock. I know there are no guarantees but it sounds like I have a better then average chance of lasting two seasons. Or at least one

Thanks for all the input guys.
