I need help picking a cam. I have faxed in recommendation forms to CC, Crane, Crower. I also faxed a letter asking Mr.Brookshire for help. To this point I have only received a reply from Crane.Anyone care to suggest a cam for my application or comment on Cranes recommendation?

1965 Beaumont 2 dr. coupe (not sure of weight)
3;55 rear end, 25.6" tall rear tires, hooker super comp headers, full 2 1/2' Flowmaster exhaust, power brakes, th350, 2000 stall convertor .
Engine - .030 over 350, stock bottom end.
Rebuilt vortec heads, stock rockers and press in studs, vortec performer rpm intake, carb, not sure yet but probably 650 vac. sec
9.8-1 compression
Objective - Just to wake my 350 up, has to be street drivable, Its not a race car but want good performance, to run on 91 pump gas

Crane recommended
solid -F0228/3067-2-14 - Adv Dur 290/300,460/480 lift
hydr - H-278-2 - Adv dur 278/290, 467/494 lift
Apparently I must have faxed my form to Crane twice as they just sent me 2 more recommendations
solid -Same as first
Hydr. - H-268-2 - Adv Dur 268/280, 459/486 lift
Another ? I figure I have to change springs on the vortecs, would I also have to use screw in studs in lieu of the stock pressed?
Thanks for help


Jerry

CC just sent me this
XE262H-10 Adv Dur 262/270 462/469 lift 110 lsa

Jerry

I don't have my catalogs in front of me, so off the top of my head...

For comp cams, I would use the xe268 over the xe262 because of your compression. I have the xe268 in my truck (see sig) and less gear than you and about .4 less compression. It runs hard from 2500-5800 rpms and works well with the 2000 convertor I have. It will fry the tires at will and is tame enough to drive daily, get decent fuel economy, and has just a bit of idle lump to let you know something is going on in there. I used the comp 981-16 springs and matching retainers and needed no machine work to the heads for clearance, but it still needs to be checked. Another good option would be the 268AH series, in whatever lsa you choose. 222/226@.050, .464/.464 lift. SHould be no clearnace issues with that cam and it MIGHT even work with the stock springs.

The 278 powermax crane hydraulic will very likely require the top of the valve guides to be trimmed because of the .494 exhaust lift. I think that cam would like a little more convertor too...something like a 2500-2600 stall, but it would still function ok with the 2000, just launch a little softer.

From crower I would (and almost did) use their "beast" hydraulic 218/226@.050, .462/.470, 112 lsa cam. Should clear everything with no problems but still needs a better than stock valve spring.

I don't know any of the UD cams by heart, so can't help there.

Any of these cams will pull 14"+ idle vac and have good driveability and strong street performance for your application.

Thanks for the input Travis

Mr.UD Harold came through. He faxed me back with his recommendations

Solid SB264F10 264/264 232/232 @.050
470/470 LIFT 110 LSA 104CL
Gives me a DCR 8.38
He recommends something like the Z28 springs so I am going to need screw in studs I assume

Hydraulic 276H10 276/276 221/221 @.050
454/454 Lift 110 LSA 104cl Stock springs would be ok here. Gives me 8.04 DCR

What ya think fellas?

Jerry

blumont- Do you know what the lash is on the solid UD grind you mentioned? Did he also give you any power guestimmates with that cam? And he said the sinlg e1.250 Z28 springs will work fine with it?

Off topic I know, just I like the look of the cam in my mild 350!

If your vortecs are stock they would like a dual pattern cam with a little more exhaust duration...maybe the xs268...its a solid with 230/236@.050 with .488/.501 Lift or so.

Allgo, He didn't mention lash or how it would perform but he did say single z28 springs

Jerry

have you ever thought about the edelbrock performance packages? There suppose to be computer matched with cams, heads,carburetorsand intake manifolds.

We're running a Lunati BracketMaster II cam(.480 lift) in my sons 355 w/Vortec heads and Z28 springs with press in studs. This is in a 81 Chev. pickup w/4.11 gears and th350, best e.t. is 13.54

Blumont,

You mentioned a 3.55 rear and a 2000 SS converter. That will work just fine with the SB264F10, and is actually more than the SB276H10 needs. I have ran the SB276H10 for about 20 years, recommending stock springs to a max of 110 lbs on the seat. I put one in a 460F Police car, with stock springs, and it would float the front end before it would float the valves.....
If you would prefer a dual pattern solid, the SB264/272F10(or F12...) works just fine. It is 232/238 at .050, .470/.485 valve lift. Valve lash on these solids is .016" hot, and I recommend them being set at least ONCE a year.
My daughter drove a 383 SBC with a 276H in it, total time on the car, about 8 years, and over 100,000 miles, ONE set of valve springs, and Crane 1.6 rockers.....
The 276H has a little lopey idle, works power brakes, etc, and pulls from idle to about 5800-6000. The 264F and the 264/272F work from about 2000 to 6500.
If you have other questions, fire away....

Harold , I am really glad you dropped in. I wanted to thank you for taking the time to get back to me on this so quick. I really appreciate it.I am trying to get hold of Dave Miller in Winnipeg now.I am leaning to your solid cam you mentioned but as I stated I am green at this so a little nervous.Harold if Dave Miller does not have that cam in stock can I order it from Lunati using that same number? Let me know and once again thanks very much

Thanks


Jerry

That's no problem with me, but I am preparing a 7-cam order for him now, and hope to ship within the week. This might save you some money/time.... Just let me know....

UDHarold

And it's bedtime for me. See you all tomorrow...

Hope you forgive me blumont but just a fe questions for UDHarold-

Would both the solid cams you have listed work with z28 1.250 single springs?

What Compression do you reccomend with these cams?

Would both those cams work fine in a 355 with an overdrive(5-speed manual), cruising aounrd 1,900@65?

No problem All, I think I have decided on the 276H10 Hydraulic cam. I am ordering it today. Hoping it will give my ole girl a lil bite to go with the bark and I can stay with the stock springs freeing up a lil cash for the 3.55's and posi I an ordering.

Allgo, I told harold I had 9.8 -1 compression and thats the solid he recommended. He did say the z28, 125 springs would work


Jerry

BLUMONT- Be sure to get the car to the track and post your times smile.gif

I see a lot of dyno #s and track times from the BBC UD cams and a few of the wild SBC UD cammed engines but nothing for his mild cams in SBCs.

Well Allgo, Winter is dam near upon us here in the great white north, my ole girl has been put to bed in the garage in a warm cozy car cover with the engine on the stand for these changes. Believe me nothing I would like better than to put it together and try it out. Its going to be a long winter dreaming about this. I may end up taking it once to the track when all done in the spring(providing I put it all together right)
