I have a 1993 Chev Suburban. 350 FI 4/Wd with automatic overdrive Th700. I dont know the differential ratios but imagine they are somehwere between 350, 373 or 411, as the truck was equipped from factory with towing package. This truck has been absolutely great to me as all of my suburbans have, getting decent fuel milage, and not using or leaking a drop of oil. I really like this one and instead of getting a new one Im gonna stick witht his one. It has been meticulously maitained especially with regards to the engine and trans, both with 230K miles and never rebuilt (only repairs have been a H20 pump, new radiator, and new fuel pump). I figure within the next 20K miles the old girl deserves a fresh rebuild and Im looking for suggestions. The truck has always done well with low RPM power but the mid range has always been very weak (passing a car at highway speed is down right dangerous, as the power falls flat on its face in passing gear! If I remember correctly factory HP was maxed at 230 and I dont remember torque figures but it is the weakest power wise of any GM vehicle I have owned. Ok so my plan is as follows:

.030 recondition orig block
turn stock crank .010/ .010
Stock rods reconditioned with ARP hardware
Flat top cast, hyper, or forg pistons up to 9:1 ratio? Suggestions?
Stock heads with some cleaning up in the intake and exhaust runners with new stock sized SS valves.
Roller, roller tip, stock new rockers? Suggestions?
(Will stick with stock TBI fuel injection)
Ok CAM I have no idea, but its gotta have a little more umph than stock, want to stick with hydraulic. SUGGESTIONS?

Truck is my daily driver and pulls my boat here and there. Most driving is a mix of around town and some highway. Occasionally drive it on the beach in 4WD. I do not by any means beat the truck, but want some more all around power for the motor throughout the lower and mid rpm ranges (as a truck like this should really not have any high rpm operation)

Right now the truck runs a stock exhaust to ta high flow cat and then opens to 3" single into a flowmaster and 3" tailpipe (which when I put on increased power quite a bit. Im leaning towards some shorty headers..Any opinions and suggextions? Also thining about eliminating high flow cat? Finally if anyone knows of a manufacturer than makes a true dual bolt on system please let me know.

Ok sorry for the long post but wanted to give as much info as possible for good responses. Let the opinions fly and thanks in advance to those who respond.
