Or..a car that will lay rubber for a full city block...A barely streetable car that people will people will unmistakably know is bad ***.
This is coming to me, I think a an already package deal. I am kind of thinking that less will actually be more.Aaahhh, gotcha. I have one of those "barely streetable" cars and trust me, it gets old. Loading up at idle, loud exhaust, lots of heat in the trans and motor which can be tough to manage... But hey, if that's what you want... You likely understand that most of the time you're at part throttle on the street so you'll rarely be using half of that 550hp anyway.
If it were me I’d forget about the solid roller and try to find a flat tappet grind that makes power at a lower RPM. Nobody will know what kind of cam it is unless you tell ‘em. Then you won't need roller valve springs and your current converter and gears should be fine if you keep the duration @ .050" reasonable.
Yes in conjunction with the roller rockers I would guess 20 or more hp loss with a flat tappet.wouldn't the roller give you better rev capability less resistance etc?
Do you have less choices with the roller? I never had one in a Mopar but have one in my Fox Body Mustang.Yes in conjunction with the roller rockers I would guess 20 or more hp loss with a flat tappet.

That's a huge cam, alot of duration for 408 cubes. I would expect that cam to be really alive from 5k up to 8k, just a guess but you might run out of air with the thermoquadI’m looking at a stroker 408 kit with a beastly comp cam.
Set up:
10 to 1 cr to use 93 octane yes, I know will lose hp
Cam, custom ground 312/597 322/ 588 @.050 solid roller, roller rockers
All forged
M1 or similar intake
850 tweaked thermoquad
MP distributor
MSD 7al2 ignition
150 shot of gas
Most importantly trick flow heads
What I really want to know is the estimated sweet spot/pull hard range??
Are you going to run an automatic ? Because the cam you want & the converter you'll need will blow right past 2500-3500 & probably 4500 before it even gets moving & not slipping. You could get away with alot less cam to do what you want something in the 250s duration at .050. I'm not a no2 guy so I'm not sure how that will work but I'm taking a guess with the cam you want to run letting in that much no2 & fuel it's destined to be a broken block or rods or something in no time.This is coming to me, I think a an already package deal. I am kind of thinking that less will actually be more.
What I really want is to have it pull like a freight train from 2500-6000
I could sell the roller and rockers get a flat tappet cam and still have money left . From what I can tell this custom groundvcam with rockers retails for around 1200. I could get at least 550 for it and that would definitely get me a cam kit, cam, valve springs, retainers, locks, pushrods , lifters etc.
Yes....Every weekend when I'm at the race track all I see are TQ's everywhere.....they are on all the fast cars..........Keep the Holley 950 for a door stop. We will help you tune the TQ...........

I didnt say the TQ won’t work. I said he’d better be a guru to make it work. And I stand by that. A Holley 950hp will be easier to tune and parts availability is much easier. And probably make more power.Keep the Holley 950 for a door stop. We will help you tune the TQ. If you want a little more air flow with the TQ, remove the choke & fast idle linkage assy. There will be a T shaped hole left in the air valve after removing the linkage shaft. Braze/weld/silver solder a small plate over the hole. Use thin metal to keep the weight down.

Anything you can do to a TQ you can do to a Holley. And you can do more to the Holley. They are simple and this wouldn’t even be a question if Holley was so stupid and myopic. And if they didn’t put out piss poor tuning information.
That is not a pump gas cam IMO. KimI’m looking at a stroker 408 kit with a beastly comp cam.
