NEED BALLPARK MAX DURATION # FOR MY LIMITED COMPRESSION

[ClassicComp]

my own 68 velle w/454 CC ret port heads,flat top pistons would run 12.30's @112.mph 1.8860fts w/a stock convertor & LS6 cam
Changed to a Crane 290 Commander series et dropped to 12.0"s @115mph.
The 10" convertor dropped it to 11.65's & 1.6 60fts
Maybe had 9.1cr ran it on 91 octane.

What manufacturer/ cam series would help get the most out of what I have? I've only used comp cams in the past and only a few at that! I've only used their magnum cams. Do yhe extreme's work for my application? Should I look at another manufacturer? Thank you again and I'll order the cam on Monday most likely. This motor isn't worthy of a Mike Jones cam but my other will be!

Back from the dead!

My 496 has a good old CC 282S cam in it with just about 9.5 to 1 CR. Merlin cast-iron large ovals.

When I got it as a 454, it had a CC 280 Magnum in it and down around 7.8 or so CR. Ran fine in a big 4x4 with large by huge tires on it.

BBC's are POWERFUL old SOB's, imho...

I still have 3 new cams for it.

1. A UDHarold 278/249, 110/106, .618" lift and needs .018 hot lash solid cam.

I bugged Harold for several years to make me a solid lifter copy of CC's great old 288AR solid street roller and he did and he gave it to me. How I miss Harold!!

2. An ERSON Hi-Flow AH, 284/218, 111/111, .542" lift Hi-cam.

3. And a Clevite Hi-cam at 309/221/327/235, 115/110.5, .500"/.506" lift.

Can I collect shit??

CamKings cam looks good.. The 3600 stall converter will be a lot of fun for street/dragracing.. You may see as much as 4100 flash stall (on slicks) behind your 454.. 4.11 just right.

You can always supercharge it later if/when the opportunity presents.

I have a early 80's 454 with oval port 781 heads and I believe about 7.5-8:1 comp. I've done some port cleanup and bowl work and tappered the guides myself (did my best with my limited porting knowledge). It is getting new rings and bearings and a cam. I don't want a small "towing" cam instead I want more performance but I don't have much compression. I know with the low comp. it won't make much power but that's what I'm working with. I have a Edelbrock performer 2-O intake or a Team G single plane oval port and 1 7/8" headers. Can any of you tell me a cam that will work good? I'll get the right springs also. It's for a 3500lb vehicle with either (undesided) 3.73 or 4.11 gears th400 with a kit and I have a stock converter or a 1ton 350 small block converter(I was told it would stall around 1,300 rpm?) and I have a holeshot 3600 converter. I want as much as the compression will give me. Sorry for the long winded post and I know it's a poor combo but I have everything but the cam and springs. Thanks.

Well here is something that you can look forward too. 2 years ago I build a 461 BBC shortblock much like yours but with flat top pistons, steel crank and balanced. On the top I had used 236 peanut port heads with some mild porting, the cam I used was a Comp Magnum 282S (I like solids) and it's .561 lift and 236°duration. I topped it off with an Air gap plus a 850 Mighty Demon, the 461 also had 1 3/4" headers. The car ran the best of an 11.70's@112 mph. Had I used the radial slicks I use now I am sure the car would do an 11.55@114, so see there's hope for you and yes my 461 was measured at 7.8 to 1 compression.
