I've been doing quite a bit of research on building this engine but one thing I can't seem to get a clear answer on is a good ballpark figure on projected HP. The block is bored .20 over. I've seen the question asked in other forums but the numbers get misinterpreted and everyone is running with .020 and claiming no HP gain. I'm talking .20 (hundredths) not .020 (thousandths). This results in 313 CID at 5.1 Liters not 283 CID and still 4.6 liters. With that confusion cleared up, I'm planning on running forged pistons and I or H rods to go with the forged crank that the 96-98 cobras came stock with. I'm not looking for an all out race car. Just looking for a fun toy that can dispatch an occasional SS Camaro with relative ease and give the Generals' finest a good run for it's money. I was looking into a Kenne Bell setup. I know this isn't intercooled but as long as I build around 9.5:1 compression and keep it around 10 lbs of boost, I should be fine on 91 pump gas with an octane booster. I'm shooting for around 500hp. Is that guess a little high or conservative? Also any other suggestions you have would be appreciated. I.E. best pistons/rods, other mods, etc. I have no interest in an eaton swap as this would be more labor intensive than I care for. Also, what thoughts are there on the IMRC deletes? I know there's more I'm not thinking of so throw everything at me. There's a lot of knowledge on this board and I appreciate you all. Thanks for any input.
