Yeah, you would need the 95 opti and timing cover and the vented harness. Jason or Dal can hook you up with everything you need there at a decent price.
As far as which setup is better. Neither. In the end they both cost about the same. With the LT4, you wouldn't have to convert to an electric water pump, but it's still $200+. With the double roller, you have to convert to the electric pump which is $130 (CSI) plus the chain, which is $70.

You can run a dual spring if you want. Those springs are good to .600 lift without having to machine the heads.
Everything should work with your port job, as long as your buddy doesn't screw anything up.

So basically I can get however big of a port job I can afford doesn't really matter how big of one I get right?? Also how much power do you think ill be running with that setup? Also with computer work and long tube headers and exhaust?

thats exactly my setup. everything you have listed. only diff. is I dont have the timing chain. since Im rebuilding my eng now, Im goin with the csi waterpump and cloyes true roller chain. also I have stock valves in my heads. you can run the stock length pushrods as long as you dont have the heads or block decked, and the valves are stock length. if I were you, Id buy a pushrod length checker and have the eng. assembled mostly to mock up the rockers on one (at least one) cylinder to see if the stock length pushrod is right for you. then buy the pushrods. I was shootin for around 475 crank HP with that setup. I think the port job will make it or break it. the best thing you can do for a tune would be a dyno tune. but those cost around $550 round here. you'll have to find out in your area. but you can get a mailorder tune from madwolf (ion) tuner@madz28.com is his email. now I had 3:73 gears in my car, but Id suggest 4.10 gears stick or auto. and I only have a 2800 stall in mine. but if you hace an auto, Id suggest about a 3500. now dont get me wrong, this combo was very fast "feeling". I didnt get a chance to get to the track or race anyone, so I dont know for sure. Ion did my tune and it was close atleast. cause when I pulled the plugs after the 300 mi.s, they looked great. and the rev limiter was set at 6700rpm, which I hit a few times while geting on it. it revs very quick and pulls strong to that rpm. now that I have a all forged crank/rods/pistons, I'll have him put the rev limit at 7500 and I'll use my MSD to limit the revs. then I can play with shift points at the track to see where the power falls off.

Oh and my$0.2 about your engine rebuild. Go with a stroker and some decent bottom end parts, you'll thank yourself later. There is obviously some expense, but you don't have to go crazy. A good crankshaft like the SCAT 9000 is a good buy and some decent rods and pistons. Good luck.

you shoulldnt have any valve float. like I said, I hit my rev limimter a few times at 6700rpm and there was no valve float at all. and I believe those ferrea valves are lighter then the stock valves.

If I was to bore my block say .30 could I still run the same setup as I posted? Or would I have to change stuff? Also can I use same connecting rods and stuff if i bore it just change the pistons?
