45 Lb/ft Below is a link to all small block Chevy torque specs.
Head bolts are 65 lb/ft. Look at the link, "Small Block Chevy" at the right for all torque specs.
Yes they will, but 305 heads have a smaller combustion chamber so it may raise your compression ratio.
Yes, they should bolt on just fine. Might get a little more low-speed torque with a decrease in top-end horsepower.
The headers for a 350 and 305 are the same.
Yes, and well.
85 ft lbs
Possibly if Chevy made a 300.
255 Ft-lb
the block & heads are the same you just have to pull the 305 out & put the 350 back in
305 heads of course, 350 heads will fit for sure and possibly 400. obviously no big block heads will fit. a 305 with 400 heads gets you a little over 352. 350 with 400 heads is a 383. add and divide
70 ( FT. LBS. )
