putting my 77 back on the street... how do i keep up...
It has been 6 years since my 77 has been drivable. Allot has changed and I want to know what I will need to keep up and hopefully beat the new generation of cars.
Break down:
3.73 posi 10"
Aluminum drive shaft
700R4
Stock stall (1800 I think)
Chevy high per. crate 350 with vortec heads (330hp)
Holley 650
March pulley kit
Hooker headers + 2.5" dual, flomaster mufflers
All poly bushings
Hotchkis springs and sway bars
Frame extensions
4 wheel disk
I think that is about it. I’m looking for a street and strip outcome. So I figure aside from a manual trans I have my eyes set on the engine. I don’t want to dive into the bottom end but if I have to I will. I'm thinking more like heads/ cam/ ECT... I like N/A engines but I would not be adverse to some forced induction or nos suggestions. If I seem to be missing something I'm open to ideas.
thanks for any and all help.

It's tough to beat an LS1, especially if they've opened the engine and swapped out a set of heads and swapped their cam. However, if you are looking for a good way to make power, consider some of the new AFR215 eliminator heads with a Comp hydraulic roller retrofit camshaft profile (240-ish duration @ .050"). Have the heads milled to get your compression ratio up in the 10.75:1 range, then put in a 750 carb on an Edelbrock Victor single plane intake manifold. Back it up with a good quality, name brand torque converter in the 4000 RPM range, and you'll have a ride that'll make you want to hang on.
Proabably $3700 worth of work.

It's going to be a lot of work, my LS1, that is now 9 years old puts out pretty close to the same power as my lightly built 404. And now, with so many cars comin with 400+hp stock... you got your work cut out for you man.
Since we're talking drivetrain only here, you got some untapped potential in that small block. A head an cam change will really wake your car up...

Just keep in mind, while a lot of cars are coming out with more and more horses stock... not all of them are coming with the torque to back it up Have fun man. Im sure your combo along with what was suggested will be a very good start.
