454 hyd ft cam recommendation 049 heads

[hereinmissoula]

This engine was built in 1988 and has not been started, car is finally finished I am helping owner get car going. I explained the leaps in cam technology in the last 20 years, going to replace camshaft for his project and get it running. Here are the specs. Street strip deal. 11's would be cool.... All done by 5500- 6k..

Car is 65 Chevelle
approx 3800 lbs.
th400 3500 stall
12 bolt 3.55 gears

454
Stock crank and Rods (ARP Rod bolts)
TRW L2349F Pistons (30cc dome i believe)
049 Heads lightly cleaned up and rebuilt, fresh valve job
Crane 99893 Valve springs , 1.7 Crane energizer rr's
Decked block (not sure how much, all receipt says is decked, assuming just enough to clean up)
Performer RPM
750 DP
1 7/8 Headers / Full 3 inch Exhaust
Msd Pro Billet/6a Box
Compression should be around 10:1 From what i calculate. More if was zero decked. Threw them .0016 in hole for 10:1 number.
CURRENT CAM is CAM dynamics 10309 296 adv 230 @.050 544 LIft I believe. Same on Exhaust.



I know I can pick up power over this current cam, Just on the quick I think numbers around xe284h sound good. ( I never run shelf but numbers are around what I was thinking.) , is a 110lsa appropriate for this build? More power to be had on 108? 106? Manners not super important but needs to be drivable. I do mostly small blocks so help would be appreciated !!!!!!

I would like to run a solid ft but would have to change springs im sure, might be able to talk owner into this.

550HP seems do able??

Suggestions????

i put this cam is a similar 454 a couple years ago. I really liked it.
Isky 396245 however its a solid.

Might go over to Team Chevelle and hunt up one of UDHarolds older grinds that the guys like. I want to say by Lunati??

UDHarold made great cams.

I mention this only because the Chevelles had more big block engines in them than all the other cars combined.

I built several almost exact same configuration
one with headers, at least one without
The Chino CA Rick Jones Cam- Mike's brother- worked better than the other cam the customer supplied
that said
the cam you have should work fine- It is not as old as the new Isky hyd cams
what do you think might be wrong with it?
put it in, adv it and retard it if you think there's more to be had then report back
CAm Dynamics were good cams in their day as were General Kenetics, Ultradyne Crane etc
do you have the timing for that cam>
1988 be sure to pre oil it while rotating the motor

Your Crane 99893 dual valve springs are fine for street strip solid lifter BBC cams.

3 solid lifter cams for you. Sort of solid lifter versions of the XE284H-10 cam you mentioned.

Crower cam #01330
Crane cam #131111
Lunati UDHAROLD cam #30110512 (this one is a bit tamer, idle)
These are all "street cams"

With all these cams be sure to check retainer to valve guide seal clearance at full lift
and correct spring installed height. I believe the exhaust spring seats are deeper on that head.
So may need a spring seat spacer to correct installed height without the OEM exhaust rotators.

ON your 049 oval port heads, what is the valve size? 2.07" or 2.19" in ,,,1.72 ex or 1.88" or?
Define "cleaned up"

if you want to step into a Street mechanical "Street roller" cam this one punches way above its weight.
It makes huge torque in a oval port 454. Great for a car like yours with mild gears.
Comp cams "Special Magnum Roller" comp #11-691-9 CB280A-R10
You will need to change the valve springs for this roller cam as it uses a more aggressive valve spring.
But it is a straight swap.
It is short duration, high lift and really moves the valves.
Needs a cam button too. Call comp cams and ask about this Magnum street roller cam, they will get you set up with the right springs. (They hide all the good cams in the back of the book.) This one is hot for your purpose.
Huge midrange torque, very responsive. Easy 550+hp easy 11's. Street strip duty. Set the valve lash tight at .016 -.020" COLD 1-2 times a cruising season. You'll like this one.

Please post back the spec's on the comp #11-691-9 CB280A-R10.

Thanks,

I know I do like their 288AR solid street roller cam.

Yes the 11-691-9 CB 280A-R10 is the dual pattern "Special Magnum Street Roller " Snotty big street torque version of that cam.
It works. is what you want if the gears are mild (3.55)
Here is the cam card. You can search it also on the Comp site.
Call Comp cams to get the springs for this one.

That one will get it done too. Yes the springs are right for that type of cam in
a BBC. It is up to you to verify seat and open pressure and coil bind
on that installation. Don`t ask, do it.

Remove the inner coil for the break in. Use a Moly enriched oil
or a Moly additive like www.MolySlip.com
Its helps performance flat tappet cams in motors oils that lack
these critical anti scuff anti wear additives.

Then reinstall the inners and set to height.
This reduced spring pressure allows the new cam and lifters to get friendly.

get time, fill this out, and I will email you a cam recommendation
http://jonescams.com/street-performance/

[wyrmrider]

Chris has put his 2cents in and Mike has made you an offer you can't refuse
let's compare the answers
fill out that form and post up all the data here so we can all share

also F-Bird is spot on about the inner springs
I'd pull the springs and test them if they have sat static for many years
and if you do decide to test the CD cam better put some fresh rev lube on the lifters

[hereinmissoula]

I'm not sure if I should share what was recommended .... ????

Spilt was smaller, same lsa .. Recommended a mech flat tapper for those springs ..

[KnightEngines]

Yeah, 99893's are suitable for a moderate SFT cam & you got stud rockers on there, no reason to not run a SFT.

Hyd FT cams are for stockers.
