I Have a set of stock heads from an 02 ZO6, these are the 243 heads with the lightweight valves. Stock yellow springs. Fully assembled and removed at 50K miles to install a set of ported heads. 210cc intake ports 64cc chambers and these will rev to 7K without valve float! Asking 650

I also have a set of Patriot Gold Dual Spring Kit with titanium retainers, kit is complete brand new. Asking 350 for the spring kit.

I have a 99-04 5.3 shortblock, complete and assembled minus the oil pan. Has a busted ring land on #1 piston. I have a set of slightly used Mahle Forged 3.905 5.7 pistons and rings. Block can be bored to fit these pistons and have a low buck 5.7. With the 243 heads and a 220/220 .550/.550 lift cam on a 112LSA this would be a ~375-400HP engine. Great low buck upgrade for that old tired 260HP SBC. Asking 500 for block and pistons.

I also have a 03-06 6.0 truck intake with a DBW throttle body and stock 28lb injectors. Asking 125 for complete intake

i also have an 07-08 5.3 truck E38 ECM engine wiring harness. This is perfect for a boat as it’s just the engine harness only no transmission controls. I don’t have the ECM but will get one and include it in my asking price. It will have to be programmed for your engine build. Asking 250 for harness and ecm.
