Just a little background on my situation:
I have a 70 Mach1 with a 351C/C6. As time permits, check it out: http://www.geocities.com/snekrs_mach1
I've done every bit of work on this with the exception of the paint. While I know the Clevelands exceptionally well, I've still got quite a bit to learn about the 460.

I've got an opportunity to purchase a set of magged DOVE-C heads for $500 from a trustworthy acquaintance. The heads will require a 3-angle, seals, springs, retainers, and locks. The 2.25/1.75 valves come with the heads. This is a good price...right ? I intend to port them, but only as much as required to clear the exhaust port of fastener humps.

I can purchase a rebuildable 460 for $100 and BB C-6 for another $200 from my local junky. I'll rebuild the C-6.

The total cost of conversion is likely to cost $800, which covers motor mounts, BB C-6 crossmember, headers, and a larger radiator. I may try my existing Griffin radiator before parting with the $400 for a larger one. In short, I need to be cost conscious, so unforuntately the stroker kits are likely to be put on ice for the time being.

I'll be pulling the MSD ignition system of my Cleveland and installing on the 460.

With a set of DOVE-C heads and an intended compression ratio of 9.5-9.8:1, what type of carb, intake, and cam, and gears would you folks suggest for a 75% street/ 25% strip car that is approximately 3450lbs ? I don't care about idle quality -or- gas mileage.

I expect people will have differences in opinions and I truly want to hear everyone's suggestions regardless of how ridiculous -or- costly they may be.

Many, many thanks in advance.

$500 is definitely too much for those heads, $200 is a more appropriate price for them. It's going to be tough to give you an engine combo. without knowing all the pieces for the car but here's a few points. For a dual plane intake a Edelbrock Performer RPM or Weiand Stealth are excellent. Cam is a tough call because we don't know if you want to run hydraulic, hydro roller, solid, etc. I'll assume you want to run a hydraulic cam, in that case something with 240 duration and .550"ish lift should give you what you want, and work with ported heads. With that much cam and a relatively light car I think you could run an 850cfm carb.

 

i bought a set of dove-c for 40$ bare

 

Three more things to think about:
1. Don't forget to budget for a higher stall street converter...probably the biggest bang for the buck. You can drop a half second E.T. for around $300.
2. A vacuum secondary carb will give you more torque and usually works the best with an automatic equiped car.
3. Definetly call a cam mfg. You can't run a lot of duration with only 9.5-9.8 compression.

I remember seeing an article in Car Craft serveral years back on building a 500 hp 460 with 9.5:1 compression. I think it used a comp ff292h cam, but not sure. I tried to build one the same way, and I definetly was surprised at how much power it made. I bet it was close to 500 hp, but the 750 carb probably choked it a little. And the torque was unreal, Car Craft said that their 460 had more than 500 ft/lbs from 3000 to 5000 (I think). From my experience, the 460's like a lot of cam because of the airflow requred.

 

Hemi; How did you ever stumble across dove-c's for 40$?

 

First of all, I'd like to say your car looks VERY nice. That cleveland is sweet looking. What are you going to do with the Cleveland? How miles are on it? I'd like more info. on that if you don't mind.

Ok, that is a bit pricey for those heads. I am particuarily fond of them. As far as a cam, I really don't know what to tell you because if you are going to drag race periodically you'll probably want something slightly radical. I wouldn't go with an Edelbrock Performer RPM, instead I would use just a straight Performer because your not going to push the 460 as high as you did your Cleveland. The straight performer will make good power up to 5,500 RPM's and you won't want to go to much higher than that. Do you know what your going to do as far as piston's are concerned? I like Keith Black hypereutectic, but a set of forged would be better. Hope that helps.

i just stumbled, when the man said 40$ i said i'll takem. i hang out at a local speed shop, also part of my job is to maintain three big block chevys that pump methane. they run 24-7-365 days a year. so the speed shop likes to see me walk in.

 

I built a very good running 460 several years ago quite cheaply using those heads. I had more compression than you desire but it was so easy I couldn't pass it up! Here goes:

D1VE 460 block .040 over, honed with torque plate
KB flat top pistons with one valve relief
Stock 460 rods with ARP bolts, picked through a whole pile to fine 8 well centered forgings.
Stock 460 crank, polished but in good condition
Clevite bearings, Not fully groved
DOVE-C heads, stock valve sizes, very mild bowl porting
Speed Pro Double springs, retainers, 5/16 pushrods, timing chain.
Ford Motor Sport guide plates, big block Chevy studs
Crane Energizer(cheap white kind) 1.7 Big Block Chevy Rockers
Competition Cams 34-652-5 Solid lifter cam
Edelbrock Torker 2 intake with 2 inch spacer, Predator Carb
Sealed Power rings file fit to bore
Stock 460 damper

I used 3 thousanths clearance on mains and about 2 and a half on the rods, Stock CJ oil pump, modified stock pan that held about 10 qts oil.

This engine ran for two years of hard mud bog racing. One time on a video tape I saw the shift light on for over a minute(6400 rpm)! We had no failures of any kind with the engine and it ran exceptionally good. I was so impressed I'm a Big Block Ford fan to this day! The Predator carb always worked super too, I rebuilt it before each season and that was it. Adjust the idle one time and forget it! We used a stock Ford Duraspark distributor with an MSD 6 AL box. This engine is still running now and the owner has only adjusted the valves and changed the oil!

We used a 4000 stall TCI torque converter and normally turned the engine about 6500 rpm. I thought this thing would be tough on bearings, but it sure wasn't hard on anything! I feel that you could build this combo for about $2500 and I think it would make 500HP easily. I didn't have a dyno at the time but I would have loved to have tested that engine.

 

Davesford,
I was just curios if your truck was ever featured at off-road.com ? if it was i loved that truck i built a 460 pretty close to your spec but instead of dove c heads i used police interceptors with 2.19 intake and 1.7 exhaust and i had everything shaved to give me 11.2 compression with the kb137's
i was shooting for 500HP and had it dynod and it came to 560 hp and almost 600ft lb of torque.
