lm7 vs l33, need advise Looks like I can get a lm7 for $650 tb to oil pan with 44k.
I can also get a L33 for $700 with 52k.
Would I be better off with the l33 since they supposedly had ls6 heads? This would be for a NA motor, so iron block is not that important.
thanks in advance
ps
anything else that might be an issue between these two motors?

I had an l33 in my silverado. The heads are the LS6 castings but don't have the same valves and springs (so I was told by a buddy in Chevy parts). I could definitely tell the diffrence between the two as far as power, the compression is a little higher due to the smaller combustion chamber.... I would definitely get the l33
