200+ lbs of puppy!
Okay, I've been searching for several days, and decided i need to ask. My goal IS a 10 second truck. i'm not going for a world record, but i run with the big boys here and a slow car is mid 11's, and i'd like to keep up 
I'd like to start motor work soon, and have it back up and running in a month or so. Most time consuming thing wuold be block work. My list is, Splayed 4 bolt mains, Eagle rods, JE pistons, the 415 cam, worked 98+ vortechs, Modified stock upper/lower intake (is the TB something that needs addressed?), ported exhaust manifolds, PTE63 turbo @ 25+ psi, 50# injectors, alky, also a 3200 stall/TH400 trans. also will be coating the pistons, exhaust ports, and bottom of the intake
1. A guy i work with has a 4.3 short block from a TBI 92 S truck that i can have for free if i just go pick it up, would i be better off to have this rebuilt or to rebuild the Sy block/crank thats in the truck now? (EDIT: speaking convience wise. is/should this be comparable to the block/crank thats in the truck? it'd be much more convient if i could just build this, then mod intake, and swap everthing over to the waiting block, and the off the factory long block.) is there a major difference in the different cranks strength wise? (reffering to the 4.3 "holy grail" article)
2. Can/should this motor be balanced internaly?
3. will roller rockers fit under stock vortech valve covers? if not what is reccommended, stock or somthing aftermarket? also reuse the factory lifters or should they be replaced? going to do hardened pushrods and better springs regardless.
and finaly, if i decide to run around with drag radials on all 4 corners, is there a major weak link besides the front driveshaft i should address? I see hoovers are running stock rear (assuming with shafts and a better posi?) what about the front axel/outer shafts?
Thanks in advance guys :tup:
