Here is a good thread about heads and cam on a budget: THey used stock RT heads which are not that much better than the heads you have. It had 60 ft lbs more RWtq than a hemi and only 20 less RWHP.

But, if you want to go STRAIGHT HP, I would get the hughes top end kit.

THat will put you way over any hemi on the road in terms of HP and TQ

 

How is your self control?

If you were willing, you could rebuild your own bulletproof trans for less than what Dr. Evil Charges. That and "secrets we won't reveal" makes me a tad nervous.

I am hoping your 4500 horsepower was a misprint.

You would need to do some serious massaging, and a very custom tune, to crank 450 horses out of any motor. (short of a big block, or, go with some variety of forced induction......) In a truck, you are going to have your power band in the WRONG place.

If you just want to race it, that would be ok. If you actually want to be able to DRIVE it, and USE it as a TRUCK, you are going to be sadly disappointed.

 

I would go this route:

1. Plenum kit and intake bolts from hughes (125 hughes)
2. 1.7 roller rockers instead of a camshaft (harland sharp) (350 summit)
3. 2.02 Valve Iron Ram heads from hughes (999)
4. SCT from hemifever
5. JBA titanium ceramic coated headers
6. MSD box and coil
7. Tune up (Cap, rotor, plugs, wires)
8. Fastman Throttle body (230 from www.thefastman.com) 52MM if you have a 5.9 and don't tow. 50MM if you have a 5.9 and tow. I run a 50MM on my 5.9.

All I need from that list is the heads. I have to put on my headers that I ordered.

I am actually very happy with what I have. Do things slowly. Take 1-2 years to complete everything. I owned a 1996 5.2 from 2004-2008. Owned my current 2ndgen from 2008-present. In all those years, all i have done is what you see in my sig. So take your time.

Unless you have cash lying around for if/when things go wrong. But if you are building an engine and criossing your fingers that your tranny holds....that is a GAMBLE.

YOu will need a supercharger, 10lbs of boost and a built engine (ARP bolts on EVERYTHING). plus a $2500 tranny.

You really don't know how much you are going to spend until a set of ARP head studs (required for boost) costs $1200. yeah, fasteners cost that much. I had them in my chevy.

 

BTW matty, how old are you and why do you want so much HP?

 

It looks like a good deal, but you don't know what kinda parts are in it from the manufacturer. Doing a 408 kit is like building a PC, if you do it yourself you know what parts you get and what they can do. If you buy one prebuilt, you have no clue to what parts were used and the quality.

 

ya all i need is heads and the airgap and 6a , prob will take me about 2 more years, i dont think my tranny has been done yet or my rear, and i have 137xxx... but as the mods i have now im in love with it, and ive beatin just about all the hemis around where i live and all fords, the only thing that will give me a headache sometimes are the bigger chevs with the 5.3.

 

what would those #'s on the bionic dodge translate into at the fly? and how much of an improvment would 2.02 heads be?

 

$4500 was the price. auto trannies scare me thats why i asked about a manual conversion earlier, but i guess i could giv it a try idk.... i have no idea what the hp would be

 

im 17. beleive it or not this started out as an oem replacement engine and from there my mind began to wander haha i dont want to be disappointed and want more later so i figured a 408 is as good as it gets for a bolt up. but idk anymore should i just do a 360?
