390hp 440ci to 500-575hp---- What is the best way to get there?

[73TXRallye440]

Currently have a 440ci with Engle K56 cam and the 440 source stealth heads. Id say 380-390hp currently. Headers go on this week so id say thats good for another 10 hp. What do you think would get me over the 500hp mark- supercharger? I cruise in the car alot so was leaning the supercharger. If so, which make supercharger would you go with? Thanks for any suggestions/input.

[mikesbbody]

what sort of supercharger do you want? sticking out the hood? or under the hood? thesuperchargerstore.com sell under the hood style superchargers if that's what your looking for.

[73TXRallye440]

sorry, I should have specified. Under hood, under the bulge hood. Doesnt have to be flashy, prefer it not to be. Just needs to get the job done.

[mikesbbody]

If you dont want anything flashy under the hood why not go for a stroker? www.440source.com the D1 supercharger from www.thesuperchargerstore.com is (imo) a bit flashy and i think (could be wrong) you may have to relocate your battery to the trunk? hopefully someone will chime in if im wrong.
The 500 h.p + you wanted can be achieved with a 440 even without the stroker and easily with a stroker.

Get yourself the following....

Engle K60/K62 on a 110LSA
Edelbrock aluminum heads (box stock with gasket match)
Indy dual plane (gasket match and clean up)
Holley or Edelbrock 850cfm

If you got 10-10.5: compression with the above stuff you're good for 575hp

hey, I currently have the Engle K56 cam and the 440 source stealth heads. How does the K60 or K62 CAMP differ from the K56?

What is a 110LSA?

How do the 440 stealth aluminum heads differ from the Edelbrock you recommended?

What about a dominator carb?

[Rolling_Thunder]

The K60/K62 cam has more duration and more lift than the K58...    the 110 is the lobe separation angle -

The stealth heads are good heads - they are close to the edelbrock heads in flow rate and style.

Dominator might be a bit much on the street... 


I'm just waiting for Ron to chime in with his 

[73TXRallye440]

thanks thunder for the input, im a newb when it comes to this engine stuff so I appreciate all the info I can get. When I buy that cam, is it a pretty straight forward install or is there alot entailed in a cam swap from the K56 to the K62?

Is this the correct CAM?

Here is a 850cfm carb I found---

Would that work or is that too much?

VERY important to get the Compression Ratio "up" ,to the stated 10-10.5:1 area, to work with the better Camshaft K62.

Match sufficient convertor & gearing,

do you have headers ?

Decent Intake ?

The K-60/K-62 is not listed in their catalogue...     however you can ask them to custom grind the cam for you - - -

The specs would be as follows.

Intake (K60)
288* Advertised Duration
238* Duration at 0.050" Lift
.535" Gross Valve lift


Exhaust (K62)
291* Advertised Duration
244* Duration at 0.050" Lift
.539" Gross Valve Lift

This will make a "Dual pattern" camshaft - meaning the intake and exhaust lobes are NOT the same...      still waiting for Ron to give his blessing

Hmmm, not sure.

CR is 9.5 to 1
Headers are being installed this week
Gears are 3.55
Torque Converter is WEAK
Intake- dual plane, but unsure what kind

what intake do you suggest? what torque converter?

Your engine should be well over 400hp....probably closer to 430 hp. The headers will help a bunch, inmo.

A little more compression (10-10.5) would help and a good carb & intake manifold.


The k60/k62 would be a nice upgrade but you would need more stall speed and more gear to make it work properly....with that cam. The valvetrain would probably need upgrading as well (adjustable rocker arms/matching pushrods) and the idle quality would change. It would also need some more compression and new valvesprings.
