adding headers will allow engine to breath better and boost up horsepower but not by much, headers also make you vehicle louder with pipes.
The headers for a 350 and 305 are the same.
yes
The headers would be the same anyway, so you can order headers for the 83 and be all set.
carb, cam, intake, headers, heads, msd igntion, or a 350
Yes, you can put headers on and use your existing carburator. You may, however, want or need to tune it, depending on how it runs after the headers are installed.
sbc stands for small block Chevy and headers are high performance exhaustAnswerSMALL BLOCK CHEVY headders (exhaust)283 305 327 350 ect Chevy engines
yes
The performance specifications at Chevy headers can be found at the nearest Chevy company that sells headers and have the specifications specified as well.
If that truck is fuel injected, yes.
if you can find the hp. of the eng., you can add between 12-20 more hp. for the headers.
Try 12 degrees initial and see if it pings. If not, try a little more.
A .030 bore alone wouldn't add enough horse power to even feel. Now, add flat top pistons, a good cam, headers, maybe a decent set of heads and carb you'd see improvement. But if you added that to a stock bore 305 you'd see the same results.
