go ahead do restall it to 4000 on the converter, with your 4l80e you need more lowend so upping the converter is good..., sounds like a good idea on fast intake, and of course the higher compression will be better, i believe you can still get away with 11.5 on pump gas (not really sure, need to ask around)...
As mentioned by ap2002, the 4000 may be a good choice since you have an 80E.

im real comfortable driving mine with a 4k stall in a 60e, if you are making it just for track use and the occasion street driving, i wouldnt be scared to run a 4200-4400 with a 80e..,.. IMO

Yea, upping the comp would be a nice upgrade if it is within budget. I am running 11.5CR with a 3400 stall (however only have been tooling around the neighborhood) and it is fine for me. Pump gas will be fine as well depending on how agressive your advance is. Keep in mind all of the crap that is needed for the FAST intake if you do not have it already (WP, Relo the idler pulley, cutting the alt bracket, spacing pulleys...) It adds up quick.

I did some calculations and I'm somewhat limited on changing the CR. If I mill my 64 cc heads to 59cc and use a .052 gasket I get 11.0 compression or 11.3 by using a .40 head gasket. The combo is not too agrressive so I assume there will be no PTV problems. Can that be checked by math instead of waiting for the machine shop to tell me.

After alot of reading I have come to the conclusion that a FAST 90mm intake will be a better choice for me. I read that the out of the box vic jr needs to be ported and confirmed that when my head ports were larger than the victor jr ports. Also I would have to swap cams to optimize the vic jr performance and I figure that the $400 cam savings and $450 that I can get for the victor jr and elbow will pay for a fast intake. This time around I'm going to make my truck more track oriented instead of daily driver. I currently have 10.5 compression and would like to know if 11.5 or 11 would be better. Also, what stall would you guys do for maximum launch and still be OK on the streets. Are there any upgrades I should do so I can spin the motor to 7k and not have worries? I already have patriot dual springs, and harland sharp 1.8 rockers.

Still haven't pulled the motor but I'm lining up other parts I needed. I bought a vengeance ported Fast 90/90 and some fueling upgrades. What air intake are you 90mm guys using? I think the K&N I have will be too small. Also has anyone installed burst discs or is that something a pro should do?
