General Engine question
1. It has perimeter bolt heads, late model LS1's as far as I know are center bolt.
2. is there any way while in the car that I can tell what kind of block it may be, 5.3 5.7 6.0? I really would like some help Identifying my motor Where is any identification that can be easily read Thanks in Advance!!
The perimeter heads are not correct. Hopefully the PO just demodded heads to whatever was laying around which ended up being the 98 heads. Worst case, he blew the engine and put whatever junker was laying around which happened to be a 98
