Hi all,
Doing a rebuild and was looking to get some additional info on my 454 block if there is any.

The block and heads are year 1975 and from a passenger vehicle.
Block is stamped 361959, HI PERF, F9, GM11
Heads are stamped, pass X, 336781
The block is also a 2 bolt main.


Is it possible to tell what type of vehicle it is originally from...chevelle, camaro, nova???


Thanks all
