I've been lurking for a while and collecting parts for a build of my 1966 skylark. I estimate the weight at about 3600lbs.

The car will be mostly street driven with some drag racing. Maybe a power tour one day.

I currently have a stock 6.0 LQ4 short block and Wegner ported l92 heads that have been milled to a 64cc chamber. I estimate the compression to be 10.1:1 ish.

The car will have a Tex Racing Mag Case t10 with a 2.88 1st gear and a ford 9 inch with a 3.50 gear set.

I currently have a GM LS3 single plane intake. Any ideas on who to send this intake to to be ported to better match my heads??

I found a Tick carb cam online for sale and was wondering if it will fit my application??

Adv dur - 278 - 287 dur @ .050 226 - 234
Lift int = .605 Lift Ex= .576
108 Lobe Separation Angle
105 installed centerline

Intake Open 8 BTDC close 38 ABDC
Exhaust open 48 BBDC Ex close 6 ATDC

I know it is hard to find a used cam to meet my specs but does this seem pretty close to what I need?? Or should I just get a custom Spec cam??

One more general question-- If I use the same single plane intake but do a 4150 TB MPFI in the future with a Holley Dominator ECU will the cam specs change vs the same intake with a good carb now??

Thanks,
Caleb

Not too bad on the cam....but only IF it's a great deal.
Most likely you will need to fly-cut for the valves (measure PTV and be sure)
You should be about 10.2:1 approximately. (keeping stock gasket @ .051)
Don't forget to get the correct spring for that cam

For your application as you list it:

• 3600+lbs.
• Mostly street driven with some drag racing.
• LQ4 short block ~ 10.1:1-ish compression
• T-10 4-speed with a 3.50 rear gear

Looks like it would be a very fun cam. I would run it.
226/234 108+3 will prevent overcamming your heavy street car. The tight LSA and early intake closing point will encourage cylinder filling, bump the cranking compression and keep the low and midrange very responsive.

How much did you mill the heads?

I'm not sure. The heads were milled when ported to 64cc. I don't mind flycutting. I'm comfortable with that. I've done some sbf and bbc engines in the past but this is my first LS build.

The cam is not a bargain basement deal. It was not used in a guy's project so I wouldn't be saving a ton over a custom cam I guess...

Any recommendations if I don't buy this one??

Any suggestions on intake porting??

Not a bad little cam. As mentioned ptv might be a little close especially with narrow lsa.

Imho not a lot to be gained by porting the intake, stock should flow heaps. You could match port it yourself though.

If it's 64cc, I would guess .04X milled, since mine are 62cc and .050 milled.
My 23X/24X 110LSA cam needed the pistons cut.
Not against the cam, but being mostly street and that tight LSA, I would question that is all.

As long as you don't mind fly cutting, I would run that cam. It will have a nice lumpy idle and good midrange torque.

If you aren't saving much $$ on the deal , order exactly what you need form Martin @ Tick. At least talk with him about it. He will be honest with you and tell you if that one is fine or not.

If the cam was cheaper... I would probably jump on it already. Mostly I was double checking to make sure I was on the right path to applying what I have read in this forum when relating it to cam cards

I'm definitely gonna consult a couple of pros and then post up progress as I jump into the build.

I wish a baby solid roller wasn't so dang expensive. I would have more in the cam set-up than I do in the entire rest of the engine at this point...

aren't they arount 66-67cc factory, i was going to say 30-40thou

same here with cam, but 108 may take a bit more

The cam above sold before I made a move.

I am looking at a Cammotion baby solid roller now. It's new and a pretty bargain price.

Duration @ 0.05 241 intake 249 exhaust .630 intake lift and 613 exhaust lift on 112 lobe separation. To be installed on 108 centerline. Valve overlap 20.5 degrees

Intake:
Valve open: 13 btdc
Valve close: 48.3 abdc
lobe area: 30.5*

Exhaust:
Valve open: 61.7 bbdc
Valve close: 7.6 atdc
lobe area: 31*

My thoughts are the intake valve closing looks a little late but how does valve lash or installing more advanced/retarded change these events??

Thanks,
Caleb

That lobe separation angle got me scratching my head......
I think it'll be a lot better on a 113+4 setup.
