rpm edlebrock headed 493 it is yay
« on: August 15, 2017 - 02:00:31 am »
hi everybody been a bit up and down with what combo to build for the cuda but I know were im at now I have a  holley street dominator intake (only because of my shaker )84 cc rpm heads just going to run them out of the box ,summit part no b 21201030 eagle 493 stroker kit should be around 10.7 comp  im told with zero deck height and 0.40 head gasket  should be here in 3 weeks yay, so I need to pick a good flat tappet hydraulic cam out now umm I really like the comp xe  295 high lift who is running this cam does it sound good in a 493 stroker , I didn't mind the comp xe 285 hi lift but feel it wont lump as much  , looking at a good strong mid range engine mainly street driven , how does it or something similar go in a 4 speed car with 3.5 rear and 26.8 tall g 60s on the rear ,looking for ok street manners and good torque around 2500 to 6000 rpm , are solid cams a pain in the ass I have never had one mainly flat tappets but I have found a few I don't mind  ,
I really wanted to run my year one hp manifolds but after chryco psycho was saying he done a lot of strokers with those but the lobe centre needs to be 112 or 114 so that means not as  much lump idle hey or can I run a 110 lobe ok ????tried calling Dwayne porter man he is hard to get hold of seems like a nice guy I hear on other sights and I think this one as well , hope I get some good replies ohh yeah comp cams and lunati must not check emails id say I give up sooo its up to you guys now lol not saying your the last choice but don't want to ask the same asked question im sure its been discussed on here already but I cant find much on 493 cams choice  . cheers cam

specs on my motor are below.
Its a 10.5 CR motor.
Very streetable, but cam duration makes
most its power in the above 3500 rpms.
Solid roller, but rarely have to make adjustments on the lash.

Cool so is there heaps of difference In those cams I notice your lift is pretty high duration at 50 is kinda the same no I'm not looking at a cam that's making power at 3500 you must race it a bit sounds like a weapon any video clips bet it sounds nice , you say I need something like that comp 251 and 257  with 564 lift and 1.5 rockers  with a 493 should be around say 2500 to 6000 rpm range id like to talk to somebody who runs this cam  just don't want a mellow idle in a 493 engine not looking for a comp thumper idle sounding one  either I understand the more lump the higher in the rpm range it works ,

Folks on here like the Lunati Voodoo cams. Might want to contact Lunati and tell them what
you are looking for.

a big block can handle more lift and duration than a small block, plus
you got lots of cubic inches.  Also, you have a 4 speed, which is like having
a high stall converter. So, I would go with a cam that has higher lift and duration.
Assuming your pistons have reliefs for the lift.

was looking at the lunati cam catalog for big block mopars.
The 705 seems like too much.  I'd lean towards the 704.

I agree though I've never used any of their cams. It just seems a bit much to me for a street machine. I've run cams that were a bit much and it kinda takes the fun out of it after the first couple miles.

As far a flat tappet cams though, I've run them before and never had to adjust them. I checked them once in a while and that's a little bit of a pain with the oil mess but not that bad. Make sure you run a quality set of adjustable roller rockers.

hey thanks guys for responding , funny you say that cuda bob about people going to another sight I got emails from another sight saying come and join us lol ,It was like there was somebody on this sight stealing members im pretty loyal I didn't bother , im running mahle pistons with valve relieves so should be ok  and bee keeper I got  some 1.5 comp pro magnum rockers I think they are called so should be ok there , im hearing you about the 704 seems like a kick ass cam I thought being in a 493 I remember somebody here  saying that will make a cam work earlier in the rpm being a stroker like its advertised at 3000 to 6500 then for a stroker its more like 2500 to 6000 ,and strokers will eat up duration so that's why I didn't mind the 705 not challenging anybodys opinions just trying to learn as much as I can I would love to hear and talk to somebody who runs the 704 and 705 in a similar combo ,yes like you said the a833 makes it alittle easyier rather than a auto with stall conv , love a video clip , ohh that link you sent me I pm him just to ask a few questions but heard nothing back yes he has a 704 lunati ,but on another note guys like and use  xe 285 hi lift and 440 soarce swear by the xe 295 hi lift in 500 cube strokers yet the 705 is smaller than the 295 comp I don't understand maybe it's in the design they all say good street manners

I go for max power, instead of cruising, so I went with the max duration
allowed for my compression ratio.

My Challenger has a 493 with Holley Street Dominator intake and 1 7/8" headers. First I had a stock dual plane intake on the engine for looks, combined with a compcams XE274H, which looks similar to the Lunati 704. The intake and cam were the bottleneck in the engine, power curve went down above 4500 rpms.
Changed to the Holley single plane intake (dual snorkel cleaner under stock bulge hood) and put a Lunati Streetmaster 302 in it. This one has 285/285 degrees, which seemed to be more suiting because I have headers.
The result is a very streetable engine (have automatic). A lot better than with the tamer cam.
