Iron block Vs. Alum. Block
I just picked up a Alum. ls1 and was amazed how lite it was compared to my lq4 iron block.I was wondering if anybody new the weights of both blocks?I want to see which would be a better choice for power to weight.
I just searched again and got the info i needed.I must off used the wrong phrase in my first search.I don,t see myself making over 500 hp,so i,m going with the weight saving.I,ll save the lq4 for future upgrades
Thanks
Thanks
