[tomsullivan]

hi,

i was just wondering if anyone knows the measurements for an ls1 engine, or could get some.

i make a quick pic of the measurements that would help me the most


i found one measurement for the length but i dont know if it is correct, i found 25.25".

thanks in advance

LOL...even though I used calipers and took it out to three decimals...I wouldn't expect them to be any beter than 1/64th or so to actual print dimmensions
