Fresh rebuilds, never been fired. Gen5/6 blocks, gm forged cranks, gm forged rods with arp bolts, arp main studs, 8qt pans with windage trays, Hardin thermostat oil control, mahle coated forged Pistons, afr heads inconel exhaust valves, scorpion rockers, Howards hyd lifters, 741 cams, 420 blowers with twin demon 850s. Engines will make easy 750-800 on pump gas 5-6lbs of boost. Built these as spares but no longer need them. Pistons heads valve train all brand new. Take them as is for 28k. Will not separate. I prefer buyer pickup but will crate them up at buyers expense for truck shipping. Located in Massachusetts. Serious inquiries only!!!

would happen have sepentine belt for 525 efi or know number for one

Will have dyno sheets next week. 28k for pair is a great deal.

Engines made 901hp @6000 rpm, 836tq @ 4600 rpm, with only 7lbs of boost and 28* of timing on 91 octane pump gas. Dyno time only, can be turned down easily by swapping pulleys. Dyno sheet available for serious buyer. A steal at 28k for pair !!
