Please help i have a 4.8 silverado 08 with a pretty big cam 3200 stall 243 heads lt full exhaust.
what should i port my 243's to if i plan on going with 102 mm from fast.
where can i get them ported i have an extra set out in the back with only 8k miles also i plan on getting a procharger and a better tune i am willing to get pretty big ports and i am also willing to get bigger pistons or anything as long as the 4.8 looks beefier and also has about 550 hp to the wheel :0 that would put a big smile on my face
i am near lubbock tx and midland od tx who does cathedral ports.
thank you ahead of time

You can just throw the 243's on, skip the FAST, and go straight for the pro charger.

i could but i would be more happier if i didnt like the numbers from a procharger. as i said if i dont like the numbers i can thro a pretty big shot of nitrous

it is a 595/605 lift with a duration of 295.295 pretty big but i dont want a turbo i think i want a procharger bc i am going to try and make higher end bettter not lower. i always have big diesels trying to race off of 60 and if i can pull a 10 at the truck with just a procharger and alot of other mods i would be happy with the look and i have all that extra space.

where r u located exactly? i am an hour and a half away from lubbock and an hour and a half away midland/odessa..im rite in the middle of these two.becuz if ur rite outside midland/odessa u need to hit up tarinitup, hes on the forums here...he daily drives an nbs gmc scsb that is definitely capable of hitting 9s soon...ive bought an engine/tranny from him and those guys know there mechanics...go check out his ride and u will prolly go from a beefy 4.8 to a 408 stroked lq9 on big boost real quick...on a side note if u plan to go boost u dnt have to get a fast 102,,stock48's truck is running 1000hp+ through the stock truck manifold and ported 317s....

I'd talk to Richard at WCCH about your head options, they have real nice StageII CNC'd 243's that may be right up your alley
