Strick I like these guys....I know Jon pretty well He was my Neighbor for a few years when I lived in Oklahoma.

I am not sure about 'advertised' hp numbers. I think some have been embelished a little....I know Jon's motors are on the money.

Re: Crates --> GM vs. Year One

Dave ,if money wasn't the issue i would go for the "Year One" engine,for the hp.and the warranty. Plus it's balanced and blueprinted. ALTHOUGH; I bought a GM crate engine last year direct from the local Chevy dealer, it was delivered to the dealer, so i didn't pay truck freight, and they ,the dealer, brought it to my house on their flatbed for free. You might want to talk to the local dealer about the ZZ383 engine. Boy its a hard decision, but a nice one to be able to make!

I have seen good feedback on the above builder. I have also e-mailed two people who have purchase these motors. I am thinking their 408ci/470hp/510tq will fit my bill. Also, for about $1000 less than the Year One motor. It also includes the distributor and carb.
