you want to shift after your peak, so the next gear falls a few rpms short of peak

So if i peak at 6400 i would shift at about 6600?

If thats the case i would like the peak to be at about 6200-6300

No you do not have to replace the lifters. i went MS3 and i had 107k when i did the swap and so far so good. And as far as peak power try not to shift over around 6200 to 6300. Over 6500 rpm the rod bolts stretch unless you have a 01 and up block.

What's so much different with the rod bolts in the 01 and up block?? Just curious. Sorry for hijacking.

Yea i know pre 01 cars shouldn't go over 6500 and i wont.

MTI x1, and the TR 230/224....are perfect if you want 400rwhp on stock heads and they lope great, only problem is with a low lsa and limited duration on the exhaust side , i wouldnt spray just my opinion

I agree! I was wondering when you'd make the jump.

Off topic... why wouldn't you want to spray on a low (110) lsa??

The whole chart is shifted to the right. I think my limiter was set to 6600.

What length pushrods will i need?

chromemoly 7.400 will do some people go for 7.425 to get rid of the sewing machine noise

Ok thanks.

I need to pick a cam soon.

Maybe a 228/230 on a 112?

Tightening LSA opens the exhaust later which hurts power on NOS and it also closes the intake earlier which increases cylinder pressure down lower in the rpm band but may even reduce power overall depending on the engine. With the compression you have I can't imagine needing too tighten LSA or advance the cam much at all! Tightening LSA also increases overlap which is also NOT where you want to go on a nitrous set up unless you have huge exhaust and even then 110 is too tight. It is just increasing reversion.

I would have a cam probably much wider in LSA with a fairly large split to the exhaust side in duration. You need to size your exhaust lobe such that it can handle along with your headers and exhaust system the power you are aiming to make on NOS.

Thanks for the parts list.
I've always liked your cam specs and wouldn't mind having it with a 112 lsa. You put down some very good numbers. That would be great to make 400+

^^^if you went with patriot gold double springs and an arp crank bolt that would be close to $900 in parts just for reference

If you did my same cam on a 112, would you have degrees advances in the cam? Say +2 or +4

With my cam on a 112+2 you will 6* of overlap

With my cam on a 112+4 you will 6* of overlap

But the VE are different. my cam on a 110+4 has 10* of overlap

So what are you thinking then?
