Compression question.

[Oldschoolpony]

Well, I ran a comp test. #1=190 psi, #2=190 psi, #3=189 psi, #4=189 psi, #5=187 psi, #6=190 psi, #7= 189 psi, #8=190 psi. This test was done with the motor cold and all plugs out. motor was not run for 24 hrs and headers were unhooked ( had to change plugs and headers were in the way)

Do these figures look good for a 347 w low miles? can the 187psi be because of differences in the comp chambers? They're Windsor jr's. I run premium, could I get better et's with av gas...110 octane and timing raise? Also, I finally found the engine builder, in mass. he said the person that owned this car previous to me dumped alot of money into this car. I was told it had a billet crank, how does that compare to a forged crank? also told me it had some really high end rods, maybe eagle's. he's mailing mee all the invoices monday. If they are eagle rods, does eagle make good high end rods?
