Aluminum Roller
Ford 302 VS 351 unmodified weight difference?
What is the weight difference between a 80's 302 and a mid 80's 351 unmodified engine? Both are stock long blocks. I'm trying to decide which engine to use in an RX7 conversion. Which ever engine I use will end up with AFR aluminum heads and a roller cam conversion. I'm just looking for a weight difference.
302 Long Block weight is 485 lbs. The 351W long block is 530 lbs. The difference is thicker casting, higher deck height and larger bearing journals.
The heads weigh the same, so the short block weight would be approximately 45 lbs difference.
