3400-7200 Lopey idle, Bracket E.T. Good mid range torque. Needs 11.5:1+ CR.
converter would be 4500.
You are probably maxed out with your heads now.
All the parts need to match.
I think the preceding step mentioned would be a lot more street friendly.
Now even I would consider boosting. Then you can aim for 800-1000 HP,buts thats a whole new engine,,,,lets see if nova SS gets in here soon

[bigblockragtop]

I went that route and started with approximately 600 hp. I changed to a procharged 496 with 800(total guess)hp. The difference is huge. The car is now very violent to drive. It went from fast to scary fast. I am not so sure this was really needed but it is done now. I have a 6 speed manual 90-10front shocks no sway bar good weight transfer slide a link and drag radials with 3.9 gears. First gear is useless 2cnd not much better I do not get to hook and go until 3rd and even that causes tire spin. I must say I picked up that mid range like you want but by the time I could get it to hook the rice rocket would be gone. Also the lower compression gave up some thump out of the exhaust. Sounds crazy but the 600hp sounded better idling and cruising.W.O.T is a different story though. I think a shot of nitrous would not be bad but that is why I went with the procharger so I did not have to worry about filling bottles and being ilegal with a nitrous bottle in the car.

Listen to BBR, my Nova is a violent ride as well, I agree with what he's telling you.

Regardless, if you feel the need for more, stay away from the Thumper cams, they're hard to tune and others agree it's more of a poser cam.

[Mr big block!]

Alright now nova, vinnie, and ragtop, Exactely what is the out come here? What i mean is what is the final advice to go on here? There have been many different opinions, and suggestions on this topic, which is the best to go with? Does anyone have any part numbers to suggest here? I do want it radical! Thank you.

[ProStreetRob]

I can only tell you this, a fully forged Big Block with proper heads and solid cam, killer rockers & girdles, and a 871 with dual quad is A LOT of fun. And not disappointing at any speed or rpm
And not for nothing but got dam they look GREAT

[Mr big block!]

That looks sweet ProstreetRob.

[Mr big block!]

How would this cam kit work with my application?
It's a Howards Cam kit. If you want to look it up of the summit website the part number is.
CL122531-10 Let me know what you think Thanks.

Ok well I love the look of that blower, but I prefer the sleeper look. My procharger fits under my hood. The other thing I like about a procharger or any centrifical supercharger is that it does not have the monstrous low end torque which makes it slightly easier to hook up on the street. You use 2 humungous carbs on that style blower I use one 850 on a 496. Mine is a 496
with a d1sc C&S carb blower cam. I get 10-12 lbs of boost I keep the rpms down to 6k, I could go more just do not need to so why do it. 6 speed manual trans(zf-corvette) ford 9" . I run a little over 8-1 compression so pump gas friendly I have a snow methanol kit just for insurance. Hope this helps.

I thought you were going to move up from hydraulic flat tappet looking for more power?

[Mr big block!]

Hi Vinnie yeh looking for allot more power. Just figured hydrolic is less maint than solid. atleast in my experience with the solids they require more adjusting while they wear and engine run. Yeh i know they are more percise and accurate power but can't i get the same power with a good hydro kit?

[vinniekq2]

no. a hydraulic cam has slower ramping than a solid flat tappet cam.A roller hydraulic cam has faster ramping than a solid flat tappet cam and a solid roller has faster ramping than a hydraulic roller cam. Use any cam other than hydraulic flat tappet and you will improve.You seemed very interested in a lot of improvement? a slightly different hydraulic flat tappet cam might make a slight difference in power.
You can pick up 60 plus horse power with a solid roller and vic junior.not on the top end

everywhere,from 2500 rpm up to the new higher max rpm level.perhaps even more on the top.
back in the late 70s early 80s 680 horse power LS-7s used nothing much more than a moderate roller,mildly ported square port iron heads an 850 on a victor.that was what the super gas guys all used for 9.90 class

[Mr big block!]

Do you have any suggestions on a bad arsh solid cam and lifter kit? a possible brand and part number i ,ay want to try? I am looking for serious midrange torque, i mean something that will plant the passenger in the seat, lol. And with the victor, i was thinking of changing back to the air gag like i used to have. Do you suggest duel plane, or single wide open, regular, or square bore? Thanks Vinnie!

I used the z-55 in a mild oval port 454
something like these profiles,plus or minus depending on what you finally decide.
I picked up 4/10s going from a performer to a victor oval port
you have to decide what you really want though

[Mr big block!]

I meant air gap victor sorry for the typo! think that's a good combo for better mirange/top end?

[Mr big block!]

Hows this for a choice Vinnie? Extreme Energy Cam and lifter set. CCL-CL11-770-8
What are your opinions on gear to gear timing? I'm thinking if gears are meshing together and making whining noises then NO! For obvious reasons. If your rear end is making noise that's a bad thing rite! So why wouldn't this apply here with the gear to gear timing? I never read much into it, but it just doesn't sound like it's a good thing, sounds like destruction waiting to happen to me?
