Sorry Don, you assume wrong, no EFI or power adders. It's bored, stroked, balanced, ported, port matched and polished heads with 1.6 roller tip rockers, 282 cam, 9 to 1 compression, headers, reworked distributor, Edelbrock intake manifold and a Holley 390cfm 4 barrel carb all assembled with ARP studs. I have been beating on this motor since 06' and it has a great torque curve, it pulls hard from about 1200rpm all the way to 5500rpm. It's a little loud with a Flowmaster 40 series muffler. It sounds like a V8 at idle and more like something foreign when I wind it up. My father in law bought the truck new in 85' and gave it to me instead of his two sons that didn't care about it. I built the motor and did everything but the valve grind, boring and balancing and the distributor. I used to run big blocks but it cost's too much and people including the machine shop were giving away 2.8L parts. My friend has a twin motor to mine but with forged pistons and runs a 100hp shot of nitrious. It's surprisingly quick.
