Sorry it's been so long since I posted, but the LS1 is going in this weekend! I'll keep everyone updated on my impressions after the swap.

For those who might not remember me...

The specs:

<500 mile LS1 shortblock
Thunder Racing 224/.563/112 cam
TR pushrods
Comp 918 valvesprings
ARP: head bolts, rod bolts, main studs
Clevite "H" bearings
8.1L 31#/hr injectors
new rings
EDIT
LR4 intake/exhaust/accessories

Other bolt ons already on truck:
LT1 fans
160* stat
free mods
K&N FIPK

Best time with 4.8 was 14.77 in the 1/4 (9.53 1/8), best mph was 97 in the 1/4 (77 1/8)

I&#39;m hoping for some mid 13&#39;s, but I&#39;m more concerned with getting somewhere in the 105-110 range mph wise.
