Make it simple and call Bob Madera at Marine Kinetics. He nailed exactly what I wanted and gave me a no BS expectation for performance.
You can tell he lives for this stuff and knows exactly what to do considering whatever goals you have.

That was the plan to start with but sometimes you have to change plans. After making the auto and property insurance payment yesterday I came up short of having enough to even buy the 350 hp cam that muscle marine has and that is just $250. There was a time when I could make house payment, truck payment, insurance and more out of one weeks check and still have hundreds left. Not anymore. Lifes a ***** then you marry one. The Dodge is starting it's death wobble thing so next payday, 2 weeks away is no guarantee that there will be money left over for a cam and Bob can't make a living based on my promise to pay him next payday. Sorry for the rant but this payday was another let down. A smart man would sell the boat but not me. Damn the torpedo's, full steam ahead.

That suks. Sounds like time to sit back and wait...but that's personal advice which you are not asking for and we should not give out.

Just curious, what are the specs on the 350hp cam

I think that is sound advice SB and I don't mind at all. I have other things I could sell to buy the cam and more and I would have in past years but now days I see that as going backwards. The next check will be freed up to use more of + I have a start to some decent overtime on it already. Some day I may tell you the story how I bought the boat the same day I got laid off while working in San Antonio Texas. I made it to northern Oklahoma before running out of fuel and money both and had to call my wife to put some money in my checking account so I could make it up to Wichita. I thought it best to keep the fact I had bought a boat quite until I got home. Boy did the sparks fly when I pulled into the drive way with the boat hooked up.Lol After 2 weeks of wet sanding and buffing it looks brand new and my wife told me it's a beauty.

Just for FYI on this discussion. I just finished dynoing another 6.2 build. It's an early model 6.2 with the 4 bbl type intake. I rebuilt it with forged pistons. Raised the compression to around 9.8. Minor bowl work on the Vortec heads. We used a Comp 270 hydraulic roller. Stock exhaust with stainless replacement risers. It made 380 HP at 5700 RPM, and over 370 from 5200 on up. Torque was 423 at 3900 RPM.That leaves a 500 RPM window from 5200-5700 where the power is pretty much flat. So as with many other 6.2's I've done, that head, cam and exhaust package works really well but pretty much hit it's limit by 5400 RPM, but if you want to turn more rpm it doesn't completely just die, just no real benefit.
Hope this helps,

Bobl, I have been reading about your great success with the 6.2s for quite some time, and have a question. The build that you speak about above , was the original efi kept , and if so, did it have to be sent off? Also I have a 98 6.2 with the 90mm throttle body and mefi3, would mine be considered the early model with the good intake .? Thanks so much for the advice

Yes, yours is a much better candidate.. A good efi intake would still help, just adapt the throttle body to it.The mefi 3 makes it a lot easier to tune. A lot of people can tune them.
