I call Summit and ask them about the Lunati 402A3-LUN and they said it wasn't in stock and recomended the COMP CAMS 11-678-5 XS-282S it is almost the same grind ,I told the seller only "that cam sure sounds like the Lunati's cam ",and I recived yesterday ,I thouth it was the Lunati cam ,but surprise it was the COMP 11-678-5 ,SHOULD I KEEP IT ,I really want to go to the track next Saturday . I sure want to installed !
BUT AS UD HAROLD SAID ,
"NOT ALL 110lbs. BLONDES ARE THE SAME "
With this Comp Cams or the Lunati cam what intake should I use the RPM AIR GAP DUAL PLANE OR THE VICTOR -454-TD SINGLE PLANE ?

I don't think Summit STOCKS the UD/Lunati cams. You have to place your order and WAIT.

I think if you REALLY want one of Harold's cams you are going to have to bite the bullet and send the Comp cam back and maybe order DIRECT from Lunati in order to get the quickest delivery.

I'd put that cam in and run it. If it's similiar the only way you might notice a differance is on an engine dyno,maybe 10hp who knows. If you want more top end go open plenium.

I'd send it back and wait. Along the road some time you're probably gonna wish you had the UD cam in there. It would be a total pain in the butt to change cams again later. You're probably not going to die soon, you can always race another day.

10 bucks says he puts it in. His post a week or so ago,asking about heads,,,he couldnt wait,,,installed what he had,but I guess when you live in Puerto Rico, it takes a while for parts and services.

ROBERT ,you sure know went someone misses his BIG BLOCK :D . I sure want to try it . what intake ,BB485 said to run the big 3500-8500rpm open plenum

I've had my cam from UdHarold for two years and if it ever wear's out I'm going to get another one! graemlins/thumbsup.gif

I like the dual plane, if you're going to spray it,use the single plane.

im running that cam in my 355....makes great power..sounds mean...I have 11.8-1 CR though...whats your CR?

I'm running that exact cam in my 454. I've had great luck bracket racing with it. Made 525hp/528tq on the dyno in my 9.6/1 motor with the performer RPM and those "worthless" rect port heads :D

Currently runs 11.30's at 118 with that combo.

and those "worthless" rect port heads I don't believe anyone has EVER said they're "worthless" Doug. Whats the rest of your combo?

I lowered the compression with the new rect port heads I took cc and they are 117cc ,now I got 10:0:1 to 9:9:1 ,with this cam it is not wise to run a high compression that was what I was told ,
Doug those are great #s I wish I can make a close e/t ,I was looking at the Comp Cams site but they donot got any compression recomendation to this cam , it can be used in a low compression motor.

Doug ,I sure want to see your engine combo . :eek:

Bob, I admit I was being a little dramatic with the "worthless" comment. Basically I got a deal on them that I couldn't refuse. Besides, they'll work good on that 540 I build once all the kids are in school and the wife goes back to work!
