Hard to say definitely unless you see the front of the block. It has Cleveland heads- the rocker covers have the extra bolts, but Cleveland heads fit a 351-W or SVO block too. With a black painted block it's VERY hard to see if there's a (plugged?) oil pressure boss on the right above the bellhousing. And the way it pulls, I also suspect it's more than 5.7 liters. Maybe Roland would know- his shop preps some of the Euro vintage racers.
