i got a 75 stingray and wanted to do some performance mods, I would like to know what is the highest HP i can achieve with out boring , and whith what mods.
When I started my engine project I planned on keeping my 350 a 350. However, I got a little carried away and upgraded to a 383 (for about $1,000 in rotating assembly) and then I bought the 465 HP, 450 TQ Trickflow kit from summit. I don't have my engine together yet, but hopefully within the month I will.
Be carefull and make sure you have twice the ammount of money you plan on spending before you start a project like this. They tend to have a way of getting out of controll.

Now saved to my favorites. But - I am a little skeptical that I can take a solid L48, add the $1650 445HP/405 TQ kit to it, and suddenly have 445/405. (It does say tested with a Holley 750 and a Vic jr). But - surely some headers would be needed too.
The non-roller top-end kits will get you close to those numbers without spending too much extra money, but IIRC you need machine work on the block if you want to switch to roller lifters (pull engine, dissassemble, take to shop, bring checkbook). And yeah you need headers for any of those combos.

Headers are your 1st upgrade period. Look at the Edelbrock top end kit. They are economical and well matched. The performer kit intake fits under your stock hood

Otherwise that is a pretty good price!
Be sure to read the fine print on the catalog page. They state that those numbers are achieved with a 9.5-10:1 compression ratio. If you just swap cylinder heads and cam, but leave the rotating assembly alone, you probably won't have that high of a compression ratio.
If I remember right, I think the L-48 had a compression ratio of around 8.2:1. I also think their cylinder heads had 76cc combustion chambers. The cylinder heads in the trickflow kit that you are looking at have a combustion chamber of 64cc so you'll see an increase in compression ratio, but I'm not sure how much.
with all of em, except the roller lifters are important. And the rest of the exhaust is as important as the headers. Don't shoot those new monster collecters through a stock cat.
The Holley SysteMax kits look pretty interesting also. They are priced around $1,500 or so and include cam, lifters, heads and intake manifold. There is one that is supposed to produce 350 HP and 400 lb/ft at around 4,000 RPM. The torque numbers are around 275 event at 2,500 so it should make for a nice neck-snapping ride. Like the above posts said, the numbers are going to vary depending on the compression ratio.
