Like the title says I have a 370CI Iron short block built by speed inc. The motor has 1500 miles on it. Was going to go a different route with the car but didn't get a chance to. Heres what she got in her
Speed inc 370 Iron block
-Billet rods
-Polished & refinished factory LS1 crankshaft
-Diamond 8.6cc Boost pistons
-Diamond Pro-select rings
-High performance bearings
-Fully balanced/blueprinted
-ARP rod bolts
This motor run perfect was broke in right and not abused. If you got any question just let me know. I would prefer a local sale here in Ga but would ship if buyer pays all shipping.This is for the shortblock only

I bought the forged 347 that Matt replaced with this motor. It was in excellent condition and made 820/823 with my Incon kit. The motor he has for sale now will have everything in it and done to it that he says.
