[m_dogg]

1.95 rockers, headers, 2.5 catback, full size IC, 42# injectors and other basic supporting mods. What do you guys think?

3.2

3.2 to start, but with a good tune, a 3.1-3.0 could be done for a DD.

I hope Ill pull it off with 3.0 or 2.9 ... sometime next year that is

i really think itll be tough to run below a 3.1 on a gen v with those mods... and be beneficial..

Why would that be? Whats the efficiency limit on the V blower?

You can run anything you want on it, what "might" be safe is another question. A properly running car and a custom tune is necessary. All cars are different.

Id say a 3.2

not thinkin efficiency limit... thinking your mods... rockers and i/c will take you pretty far... but a gen v is more efficient as you know... im just thinking itd be too much pulley... i know of cammed/i-c'd guys with gen 3s that only run 2.9/3.0s because it is what works best for their setups...

Do you have any trans work done?

Not at the moment. I will be getting a built tranny though, I doubt that almost 100K miles stocker would survive with those mods....

I ran a 3.2 on my 04 with almost the same set up as yours. THat's equivelant to a 3.0 on a Gen III

IIRC, you said you still left the SSIC plumbing, pump, and heat exchanger while using the full size IC. That was definatly a major choke in the system.

Why do you want to run 1.95's? It's really a waste of money. The reworked stockers at 1.9 lift is actually MORE than you can take advantage of on stock heads. 1.84's flow roughly the theoretical limit of the stock ports at the shorter duration of the stock cam. The only exception would be if you were running a stock '98 cam (which has a touch more duration on the exhaust side). 1.9's are plenty.

Also, the Gen V will boost more than the Gen 3...so a 3.1-3.2 would be best all around. Although, if you are going for drag times, you could drop down to a 2.8, pull a crapload of timing, run slicks and pray for traction and no trans breakage. The advantage of running too small of a pulley is the big TQ you make down low. It's an advantage because of the weight and final drive of the W-body platform. Keep the revs below 6K and it's a winner.

I was told the higher lift the better therefore the 1.95 idea and I dont really want to cam it...Im no expert so I better isten to one An

Thank you for all the replies!

Yeah, everyone thinks more must be better...

Having a little more lift than you need is ok, but the higher the lift, the more of a chance of pushrod interference too. On L32 heads this can be a problem. If you must do the aluminum rockers, do the 1.84's...otherwise stick with the reworked stockers. There really isn't an advantage to the roller tips performance-wise though. I also feel the balance is better on the reworked stockers, so using stock springs is still an option. The roller tip is heavier, so stiffer springs is mandatory.
