SBE took a dump so now in the market for a new long block. Priced out TSP & Thompson Motorsports, and Thompson Motorsports is a little bit more budget friendly. I’m doing the ARP main stud upgrade so it’ll do 1100 hp,
4.00 stroke, and Wiseco pistons
This will be paired up with my existing equipment.
ECS 1500 (will be doing a smaller pulley and max out the blower)
DSX Aux pump
FIC 127# injectors
ATI balancer
McLeod RXT clutch
OEM LS3 intake manifold
Speed Engineering 1 7/8
High Torque Starter
