F11: 228"/230" .576"/.595" 2200-6600 RPM
F13: 230"/232" .595"/.585" 2500-6800 RPM
either on 112 or 114...
Hmmm. Is your 98 otherwise stock as it says in your sig? As above, you would want a stall. But you might also want a lot of other things... Have you also considered the RPM range of the cams you are proposing and how high you are willing to shift the stock rod bolts and 4L60E?

I've run cams from mti,Texas speed, thunder, SOS, and futral...
all of my best cams have been from Futral...
consider letting him make you a custom grind to fit what you need it to do... you will be much happier than with just an off the shelf grind...
I'm a Big Custom Grind from Futral

All I was getting at is that the peak power and subsequently shift points should ideally be a bit above the stock limit, and a stock 4L60E doesn't really like RPMs above 6000, and the pre-01 rod bolts aren't really the best choice if you will be spinning over 6200. So if you keep the stock shift points you will leave power on the table, and might as well have picked a cam optimized for a lower power peak. Of course you could go ahead and shift at 6600RPM and take your chances.

going with a lower LSA will narrow your powerband...and make it more peaky with typically a slightly higher peak HP/TQ up top..
going with a Wider LSA will in general make your powerband Wider as well and will typically net a slightly less peak HP/TQ with a flatter curve
if you want to lower the powerband you advance the cam...meaning 112 LSA with a 108 ICL(112+4) or if you want to raise the powerband you retard it..meaning 112-2 or 112-4)
Most people dont want to raise their peak HP RPM... but it can be very beneficial in an all out race car and it can create some PTV clearance on an extreme cam...
Take the Cam exactly as it is, or ask Allan to make you a Custom Grind to suit your needs

Loved my f13 but if your talking off the shelf cams take a look at the torquer v3. My car picked up almost 20rwhp just by swapping to a v3.
