How Big can a 5.2 get?

Not much progress here, pulled three pistons and noticed there were strange scratches in 1st rod bearings. Now I have to find out what caused it, rod is in machineshop and theyll measure it. If its round, then its must have been dirt what caused it, but I have to find out.

But hey, I got my Proflo4 :thumbsup: View attachment 1715300500
Semi-delete that last reply of mine: I replied to a muchvEarlier post of yours...but, how high are you going to spin that. 318 ?? - that's a high Rev midrange torque manifold like hovering around 4'500 rpm constant like circle track. + things can't be TOO expensive in Finland if you've got KB pistons & proflow injection. ,( not as tough as here in NZ, we pay near 45% extra to $US with exch rate + the high cost of Shipping 9,000+ miles, then there's the +15% GST which then incures another $176+ flagfall in customs' creative surcharges.
Cheers anyway. T
