I need some advice from the cam gurus on here.I recently purchased a high compression 408 with forged internals ,diamond +13 dome pistons ,cam with unknown specs other than a part number from a place called custom cams inc. I know a custom grind would be best but I just have to ask.
Heres my question I have a 243/251 623/623 on a 112 laying around,how would this cam perform in this engine ?my setup is a different than most on here since it in a truck. thanks in advance

my setup is
408, ls3 heads milled .030,lts
holley hi ram with 92mm tb
lvl 6 flt 4l60e
4100 triple disc stall
4.30 gears
4300# weight

 

That's alotta compression, what sorta fuel you running?

Cam sounds like a good one for a stroker, although many like to run a little wider split on stock LS3 heads.

 

iam running 3 gallons of c14 to every 5 of 93

 

There is no need to run a wider split on LS3 heads. That is seemingly a myth. Spin Monster has a very popular camshaft for the LS3 vettes and it has no split.

 

Does anyone have any recommendations on what might work better

 

You dont need to go that big to make good power. The lower rpms will suffer somewhat.
I havent looked at those lobes, but lobe design is key over just using a big cam. If you want to run something different, we can set you up. Otherwise run that one.

 

With the Holley Hi ram having a shorter intake runner length than a factory manifold as well as a different plenum design it really deserves a different camshaft.

Especially with as much compression as you have.

I would also recommend a wider split.

 

I dont think they are much diff from most single planes out there as far as runner length...the "mid rise" is.

 

5" for a Victor Junior/Super Victor.

7" for a Hi-Ram.

10" for a stock intake give or take a few tenths.

It's enough to make a large difference in power band and where that power band starts/stops.

I was more so referring to the fact that his cam looks like it was designed for a stock style intake manifold and that the amount of compression he has really deserves a shot at a custom grind to be 100% optimal.

 

I just remembered I also have stangkilr old cam out oh the silver Camaro its a 236/251 641/611 112 . motor is also setup for nitrous

 

martin you actually spec'd my last cam for my truck and it worked great .iam just pinching pennys after the new motor ,new wheels and new suspension heres an idle vid.

 

Every setup could benefit from a custom grind. But he has a decent cam. That other cam the op just posted looks a little better and follows alot of "torquer" cam styles from alot of companies.
I would run the first one. That second one will likely take alot better spring set than you may have room in the budget for.

 

iam actually running pac platinums. and the other cam is a futral grind

 

I thought it looked familiar. They like those intake lobes. You will likely see the same results with either cam. That futral may act a bit better on the street and may possibly make a bit more power.

 

this is the new set up

 

I remember now! Well, as you know I would be more than happy to help you with your new set-up as I helped you with the old set-up.

What were the specs of the old cam?
