Do you think a 3800 stall is to big for my combo?

 

yes , just my opinion, sounds like you need more like a 2800-3000

 

Its a matter of personal preference. Im running a 3500 and am perfectly happy with it, while others may consider it completely 'unstreetable'. (whatever that means) In any case, definitely go for a small dia. (9.5-10in) with a lockup and get an auxillary cooler. In my opinion, the only real downside to a loose converter is the amount of throttle initially needed to get the car moving.

 

I dont think its too big... In fact I think its just right for maximum performance out of your combo.

 

It will be a fast combo, but it will drink gas faster then anything! Your stall rpm will be way past your cruising rpm and traffic driving rpm. It will make tons of heat and love gas.

 

I'm with 88 iroc on this. It will work and be great off the line, but with the small duration of your cam a 2800 would've been a better choice. You want your stall to kick in just before or right at peak torque and with you small cam it's going to be a little lower than 3800.

If in fact it is a 9"-10" convertor it will be fine for street driveing, not going to break any mpg records, but you proabaly did'nt built this thing to try that either.

A 9"-10" low rpm stall convertor like 3500 or lower is usually pretty tight on the bottom side. It's not until you get into the 8" race convertors that they really loosen up at lower rpms. The truck I drive for example had a TCI 10" convertor intially because the owner thought he may street drive it and they set-it up for a 46-4800 stall speed. You could start the truck moving at prett low rpms since the convertor was soo big and they had to tweak the fins to the max to try and get the stall speed upto 4600rpm. Fins were maxed out as far as angle is concerned and the convertor let go after the first pass and dies a slow death till the sprag went ca-blooey. The 8" convertor in there now we can set the idle much lower in park since it does'nt lug it down when slipped into gear and it usually goes to 2K-25K before the truck moves an inch.

Right your you may not be optimized, but you'll have room to grow with the motor. Bigger cam and your heads/convertor are gonna love it - that is where ALL your power comes from period, and you'll be impressed with the new et's and mph. That small cam is'nt even taking advantage of what your heads have to offer.

 

Is there any way i could hope to hook this with nitto 555s
?

 

While drag radials are starting to make a name for themselves, all you can do is try them and see what happens. Regardless of how bais I am to tires, I'll take a tried and true slick over anything else any day of the week, simply because they are tried and true for many years, many cars, and many classes.
