Edelbrock Victor Jr heads and a COMP solid roller cam. pick out one that fits your application. whats your CR?

Just my opinion... okay
1. Get a camshaft that better matches you intake and cylinder heads. For example, that victor jr. intake is most efficient in the 3500-8000rpm range. I don't know about how your heads flow... but your cam selection should reflect the best operating range of the other two components. 283deg cam is IMO not enough to take full advantage of the kind of flow the victor jr. is capable of.
2. 410:1 gears.
3. Shave as much weight off of the car as you possibly can stand to. Like the back seat, passanger seat, any subwoofer and amplifier equipment you may have in the trunk etc...
4. Suspension and tires are a must review. Especially if you are clutch dropping your baby at say idunno... 3000-4000rpm, you gotta hook. Oh yeah, might want to beef up the rear end while your putting the 410's in.
5. After you've done the above... go to the track with a pocket full 'o jets for that 750 Demon... and practice, practice, practice. Your holeshot technic will likey change with the new set-up. Get that 60 footer down !

I've seen 5-speed 390 horsepower 5.0's run low to mid 10's in the 1320, with great driving and a well thought out build. ISYN! Remember though, these are just my opinions

Good luck, keep us posted.

okay my c/r is 10.5 93 pump, can you give me some specs on what cam you would run i like the 373s but will c/o if you think to tall to get in the low 7s how about the port job on the trick flows they are 202/160s stock the car is pretty soft now thanks for the responce.

Indy

Now this is a very very rough idea, k.
In a 3200lbs car you need approximately 475-500 flywheel horsepower to be in the mid to low 7's in 1/8th Mile. Now having said that, you still need great traction and some good driving skills. With that horsepower figure in mind, check out the link below if you already haven't, to get an loose idea of what kind of components you will need to make that kind of power. Again, all just my rough ideas, so don't hold me to any kind of warranties. LOL

thanks nice link, what i have planned should get me close but i think i will look at a 408 stroker that will do it .

Indy

Yeah, even better. That's my over the winter plan. Build a 408 stroker for next season.

still need more head though! just thought id throw that in there.. send them to tea, with a blank check(jk), and put a cage in the car while they are gone, cause it will never be the same!

rfbowers

yea thats part of the plan to cage the car its got ttops, porting the heads will it be sufficent ,or do you think i need a new set?

immr.mustang

there are a lot of good head porters out there, starting with TEA, but I would look at what you would spend on porting, and coinsider selling them for a set of TFS R heads or High Ports a the foundation for ur build. You will end up doing it eventually anyway.... I have the smaller R heads on my 383 and wish I woulda got the larger ones already. The stock TW heads will work for u for now, so use them till u find someone wanting to trade down from a vic jr or R head or something... it happens. Just not often, at least u could sell them for 900 bucks and throw a few with that and get some vic jrs to start with, they are good as well, and respond very well after porting.
