next build coming around now. 305 to 355

ok. if it weren't for this site my car wouldn't be doing as well as it is. thanks to everyone that came across with ideas and especially EAGLEMARK for dialing it in. now it is time to replace my low oil pressure put up wet 305. I have a 350 engine in the garage from a 91 caprice wagon. tbi. what I got was the long block. in good shape. going to get the machine work done on the bottom end. .30 over and 10-10 on the crank. now I am kinda stuck on the heads. want a good running engine. have the 193 heads from the engine. I also have an lt1 cam on hand. don't want to go completely wild either. wanting in the 300hp range.
what I have
1. 1991 lo5 350 long block needs rebuilt .30 over and 10-10 crank.
2. 193 lo5 heads need gone thru
3. lt1 cam

ideas and maybe's.
1. better heads----vortec, port mine, edelbrock, afr???????????????????????
2. better cam----????????????????????
3. which tbi will I need 350 stocker or bigger

mods on car
1. hooker shorty headers and ypipe
2. hp cat
3. magnaflow catback
4. ultimate tbi mods
5. built trans-----400hp 400 tq capabilities.

again thinking 300hp range. don't need egr for visual. but maybe to help pass sniffer.

any and all ideas wanted. even the smallest ideas can be the biggest contributors. please tell all.

keep in mind that cam with port fuel injection and optimal runners, higher flowing aluminum heads, way more compression, and huge timing advance barely pushes 280 at the crank.

the lt1 cam wont get you near your power goals on the low compression iron headed engine like that, not a chance man.

work on your heads, try to get a bit higher compression out of 'er, and throw a real cam in there, you'll probably make it with a good tune. i really like 211/219 in a 350, but not completely sure what's optimal for tbi like that.
