So basically i want a bit.more out of my 4.8. I been reading and what not and i think i found what im gonna do. Basically my wife took the truck cause she likes it bettter than her cat so i dont want it to be a speed demon but have more ***** then it does and be streetable. Im thinking a isky triple 12, blackbear tube, 2800 stall, airraid jr intake tube. And possible the ls intale and throttle body. Any opinions on this setup?

Whats the deal on the 243 heads to? People say they nolt.on then others say they wont work.on the vortecs. Also milling them. Im getting people tbat say. 030 or. 045. Im not really a motor guy

you have to have the 243's milled to bring compression back to stock.

for a 4.8 you'll need a 3200+ verter and 4.10's at least to feel anywhere near quick... My 4.8 RCSB with a 220/220, 2600 stall, 3.42's is a DOG

That high of a stall? Sorry tbis.is my first automatic. I dont understand automatics or anything about them. I dont need it a sleed demon like was stated since.its for the wife. Just more than it has

for just daily driving, my reworked TB stall isn't bad at all, but when it comes to leaving hard from a dig its terrible.

Triple 12, some 4.10's and a decent stall will help it out. I will say, try to find a local tuner. Mail order tunes can be nothing but a headache at times, and can leave a lot on the table.

Yes is mostly daily driving. But the sac drag strip isnt far away from me. And i still owe money on the truck so im trying not.to get to much into.the motor. I was recomended a 2000-2400 stall for.dailg but.like.i.said.i know nothing about automatics

I would go at least a 2800 stall I had a 258mm 2800 and it drove great for me when I dd my truck with a 223/230 cam in my 5.3

TooNasty

So basically i want to know your opinion then before i break out the credit card right now. Isky triple 12, 243 heads milled. O30, yank 2600 stall, 410 gears,vette servo?

If you're going to drop the money on worked over heads... you may as well do an engine swap. Honesty. More power, less money.
