I'm not 100% sure but I believe the early model years were not desirable. Also, someone may correct me but the 300's were weak and only made 275-280 ponies.

ok but 275hp fresh water only for 5k? sounds like a good deal to me.

Thats cheap enough to buy and send to HydroTech for a stage three kit. I think it will then make 400hp. They had a Triton bass boat running around 117 with one.

And I will personally vouch for the power of a HydroTec-modified HPDI...
