Re: compression? hp? torque guesses (i do not know)
New illuminations of knowledge have descended upon Detroit's engineering laboratories, permitting fresh lodes of horsepower to be extracted from clean-burning, no-lead-fueled engines, which means that the new 1978 Corvette comes to the showrooms with as much as 220 hp available from the optional L-82 350-cubic inch power plant. (A respectable 185-hp — up five hp from 1977 — is packed into the base L-48 engine.)
882 castings are the old style "heavy weight", 76cc combustion chamber (port size is in the 160cc range)
Note that the 882's came in both 1.94 and 2.02 intake sizes from the factory. An original 74 Z-28 LT1 had the 2.02 versions with screw in studs and guide plates from the factory.
The compression ratio, with the dome you described, will be around 9:3.
The head flow numbers could be improved with Vortecs. I'm not guessing at the HP.
Cheers
